Murder on the Orient Express - Christie's Mysteries

Night Train to Perdition, Act III

Posted on May 31, 2020April 30, 2021 by Harley

See Night Train to Perdition, Act I, for a summary of Murder on the Orient Express, and Night Train to Perdition, Act II, for a summary of related true-crime cases, including the kidnap and murder of Charles Lindbergh, Jr. The post you are reading details the forensic science responsible for the capture and conviction of one of the kidnappers, in particular the wood evidence provided by the ladder used in the kidnapping.

The Wooden Witness

As noted in Act II, two key pieces of evidence were discovered immediately following the crime at the Lindbergh estate: a handwritten ransom note and a custom ladder. In their preliminary examination of the three-sectional ladder, the investigators postulated that the user was neither too tall nor too short and was left handed. The left handedness of the user was based on the pattern of saw blade cuts in the wood as well as the placement of the ladder to the right of the nursery window, which would allow the user to navigate entry into the nursery from his left side. The runners used in the ladders appeared to resemble wood crates that were used to protect bathtubs during transit, and police reported that the ladder was similar to those used with pipe organs.

However, these initial theories brought investigators no closer to an actionable lead. Dr. Erastus Mead Hudson, an independent fingerprint expert and specialist in chemistry and bacteriology proposed to examine fingerprints that may have been left by the kidnapper or kidnappers on the ladder. Instead using fingerprint powder, which was the custom practice at the time, Hudson used silver nitrate (AgNO₃) to identify prints. Unfortunately, the ladder had been handled so extensively since the kidnapping that there were approximately 500 latent fingerprints present, which could not be used to identify any criminals.

Silver nitrate interacts with salt deposits found in human sweat and shed with fingerprints, which can then be visualized with ultraviolet light.

In the middle of 1932 and still at a loss for any leads, the investigators turned to the federal government for assistance. They sent the ladder, a chisel that was also found at the Lindbergh estate, and a soil sample to the Department of Justice. Drawing on the expertise within various federal departments, the DOJ sent samples from the ladder to the US Forest Service, of which 7 samples were sent to the Forest Products Laboratory in Madison, WI, a joint research venture with the Forest Service. Upon receipt, FPL Director Carlisle P. Winslow told Arthur Koehler, considered the nation’s top wood identification expert, to disregard all other projects and immediately identify the source of the wood in the Lindbergh kidnapping ladder. To do so, Koehler would apply his specialty in xylotomy, which is the art of preparing sections of wood for microscopic examination.

The Wood Expert

Arthur Koehler had established himself as a skilled xylotomist and had been serving as an expert witness in criminal trials following his promotion to the Head of Wood Technology at the FPL. He had recently testified in the murder trial of John Magnuson regarding the source of wood used by the criminal to encase a bomb, which led to a conviction. Koehler had even offered his assistance to Lindbergh after the kidnapping with a personal letter:

I read further in the newspaper about that homemade ladder left behind by the fellow who had done the crime and I grew excited. You see, that ladder, because it was made of wood, seemed just like a daring challenge.
Within a few days after that I wrote a letter to the Lindbergh baby’s father, saying I thought it might be possible to trace that ladder’s members until the wood matched up with other wood so as to compromise the man involved. Of course, I’m no Sherlock Holmes, but I have specialized in the study of wood. Just as a doctor who devotes himself to stomachs or tonsils or human vertebrae narrows down his interests to a sharp focus on the single field of his pet passion, so I, a forester, have done with wood.

He did not receive a response from Lindbergh.

Less than one week after receiving samples from the kidnapping ladder, Koehler had identified the various sources as Douglas fir, paper birch, Ponderosa pine, and Southern pine through comparisons with the FPL’s library of wood specimens. After submitting his report to the Department of Justice, Koehler wanted to continue helping with the investigation, his goal to make the ladder a “wooden witness.”

The Wooden Autopsy

In early 1933, the New Jersey State Police would take Koehler up on his offer. Koehler was given full access to the ladder, which he dismantled to perform an “autopsy.” Each rung and rail was numbered, measured, and calipered. Koehler identified the source for each piece and closely examined the components for marks made during the assembly of the ladder. As relatively few sources of wood were used to construct the ladder, Koehler concluded “that the maker had a limited amount of material to choose from.”

Among all the pieces of the kidnapping ladder, Rail 16 seemed to offer the greatest potential for confirmatory evidence to match to a criminal. Rail 16 was North Carolina pine (the same as Rails 12 and 13), but it was more knotty and had not been machine planed. Rather, it had been hand-planed on both edges, leading Koehler to believe that the rail was worked down from a wider piece of wood:

Why he planed both edges of rail 16 is a mystery unless it was rough edged to begin with. The edges were not always at right angles to the face, and scratches made by the plane wobbled back and forth along the edge…the scratches left by a hand plane on both edges of this rail were exactly the same as those on one side of each of the [cleats], proving conclusively that they were made by the same plane, and presumably at approximately the same time, probably when the ladder was made.

Furthermore, Rail 16 had four nail holes that had been made by square-cut or 8-penny iron nails, which had been phased out of production by the end of the 1800s in favor of cheaper wire nails made from soft steel. In the 1930s, square-cut nails were still used in home construction, and the regular spacing of the nail holes in Rail 16 suggested they may have come from a building.

Keen to pursue multiple avenues of investigation, Koehler also fully characterized the marks from the machine planer used on Rails 12 and 13. He sent letters to the known manufacturers of wood planers to inquire as to which mills they may have sold the characteristic planers, and then solicited the mills for samples for examination. From April to September 1933, Koehler sent a total of 1596 requests and received 23 samples. Despite the small number of samples, he was able to identify Rails 12 and 13 as having been planed in a mill in South Carolina by examining the planer knife marks microscopically and measuring the marks to 1/100th of an inch. Ultimately, Koehler was unable to trace the kidnapper(s) based on Rails 12 and 13 because the Bronx lumber yard from which it was likely sold was a cash-only business.

Meanwhile...

At the same time that Koehler was examining the wood of the kidnapping ladder, the police were actively tracing the ransom money. The $50,000 that was paid on behalf of the Lindbergh family by the go-between John Condon primarily comprised $20 and $10 gold certificates. Elmer Irey, an IRS accountant, proposed this mechanism to allow for easier tracing of the ransom money as the gold certificates were being phased out of circulation. The remaining ransom money was $5 bills with red seals and red serial numbers. All of the ransom money was printed in 1928, and a list of the serial numbers was sent to banks across the country.

Bills from the lot of ransom money would occasionally surface over the year and a half following its payment in 1932, most often in New York City. On 17 Sep 1933, a man paid for 98 cents of gasoline with a $10 gold certificate at a gas station in Manhattan. The station manager questioned the legitimacy of the bill and wrote down the man’s license plate number in its margin, in case the bank refused to deposit it. The manager questioned the customer about the bill, who was reported to reply, “I have a hundred more just like it.”

The license plate number was traced to Bruno Richard Hauptmann, an unemployed carpenter who was pulled over for a search shortly after leaving his house in the Bronx. When detectives found money in his wallet with serial numbers matching the ransom money, he was arrested.

The Wooden Key

Upon hearing of Hauptmann’s arrest, Koehler suggested that investigators take note of any lumber in his house that may have been used for Rail 16 as well as for any woodworking tools. In their first search of the house, investigators found a total of $13,750 of the ransom money and an automatic revolver concealed in wooden 2×4’s in the garage; they also found a large wooden plane with a nicked blade that could have been used in the construction of the ladder.

At the time of Hauptmann’s arrest, a news article reported that he once worked odd jobs at the National Lumber and Millworker Corp in the Bronx, where Koehler had traced Rails 12 and 13.

During a second search of Hauptmann’s attic, the investigators noted that the flooring comprised 27 pieces of 1×6 North Carolina pine. The final board on the south side was not the same length as the others, and they were able to discern that a piece approximately 8 feet long had been removed, leaving traces of saw marks and saw dust. A sample of the remaining board and the nails that had been used to connect the board to the joist were provided to Koehler for comparison.

Koehler observed nicks in the largest knife of the plane recovered from Hauptmann’s house that produced marks exactly matching those on Rail 16 and the pine rungs of the ladder. He concluded, “There is no question but [that] the rungs and rail were planed with that plane.”

The nails removed from the boards in Hauptmann’s attic fit into the holes in Rail 16 precisely, which lead Koehler to conclude “the board probably was removed from some of Hauptmann’s previous work either for others or for himself.” Koehler testified before the grand jury at the Hunterdon County Courthouse in Flemington, New Jersey, to these points. Along with testimony pertaining to the ransom note, ransom money, and various eyewitnesses, the grand jury found enough evidence to indict Hauptmann for the murder of Charles Lindbergh, Jr.

Meanwhile, Koehler continued his examination of Rail 16 in comparison to the wood removed from Hauptmann’s attic. He and the investigators took Rail 16 to Hauptmann’s attic, where it fit snugly into the place of the missing board. Koehler reflected that “Such a result could not happen as a mere coincidence.” Koehler had calculated the probability of all 4 nail holes matching the joists in Hauptmann’s attic perfectly as 1/10¹⁶, and he dismissed the possibility that this was mere circumstantial evidence.

1/10¹⁶, or 1 in 10 quadrillion, is the probability of 2 people randomly picking the same word out of 110 billion average-sized books.

Finally, he compared the grain, which is the appearance of the natural rings of a tree when it has been cut lengthwise to form a board:

It is a pattern that is always varied and yet the pattern of the grain in the ladder rail and floor board matched as perfectly as if the interrupted curving lines they plotted years ago had been etched within the tree just to be a trap for anyone who dared so to misuse wood as to form it into a kidnap ladder.

Every tree within itself has written all its history. The growth in spring shows white and pithy, but in the summer the slower growth becomes, in most trees, darker tissue. This is repeated year by year, and that is why these rings seem double and confuse those who try to say a tree is such and such an age. Count the band of white and black as one year’s growth. The board end of the piece of flooring that had been robbed to make a ladder showed its rings quite clear, and so did the ladder rail. A gap of one and three-eighth inches had been trimmed off, yet the rings matched.

The Wooden Evidence

At Hauptmann’s murder trial, Koehler testified his findings regarding Rail 16, but he was challenged by one of the defense lawyers, who stated, “We say that there is no such animal known among men as an expert on wood. That is not a science that has been recognized by the courts; that is not in a class with handwriting experts, with fingerprint experts or with ballistic experts. That has been reduced to a science and is known and recognized by the courts.” The judge allowed the defense council to cross-examine Koehler to ascertain the extent of his credentials. At the end of Koehler’s lengthy exposition regarding his publications in the field of wood science, the judge confirmed he was indeed a wood expert.

Koehler provided the court with complete details regarding his examination of the kidnap ladder, in particular Rail 16’s nail holes and grain. His xylotomical examination of the wood source and grain was essential to tying Hauptmann to the ladder used in the Lindbergh kidnapping. Following the testimony, Koehler was lauded as “the only real detective (in the case)” by the Reading, Pennsylvania Times, and The New York Post wrote,

The Hauptmann trial may go down in legal history less as the most sensational case of its time than as the case which brought legal recognition to the wood expert on par with handwriting, fingerprint and ballistic experts.

After 42 days of testimony from Koehler and others involved in the Lindbergh case, the jurors retired to deliberate on the verdict of Hauptmann. Less than 12 hours later, the jury returned with a verdict of guilty. The judge passed down a death sentence to the convicted murderer of Charles Lindbergh, Jr. Koehler’s testimony stood up to several appeals by Hauptmann, and on 03 Apr 1936, his death sentence was carried out by electric chair. Hauptmann never confessed to the crime and never indicated if other kidnappers were involved.

Koehler continued working as a wood identification expert but never in so sensational a trial as the Lindbergh case. He died in his home on 16 Jul 1967 at the age of 82. Although wood evidence continues to be valuable to forensic science, it has never again been at the forefront of a crime as in the Lindbergh kidnapping.

Night Train to Perdition, Act II

Posted on April 29, 2020April 30, 2021 by Harley

**Contains major plot spoilers for Murder on the Orient Express .**

See the previous post, Night Train to Perdition, Act I, for background on Murder on the Orient Express as well as a synopsis of the book. The post you are reading will summarize some related true-crime cases, particularly the kidnap and murder of Charles Lindbergh, Jr. As mentioned in the previous post, the setting of a railway train is particularly evocative for a mystery. To date, no single crime has comprised all the elements from the novel, but there have been several noteworthy cases involving trains since its publication.

Maria Farcasanu

In 1935, shortly after Murder on the Orient Express was published, the body of a Romanian fashion designer named Maria Farcasanu was found near the tracks of the Orient Express in Admont, Austria. She had been traveling from Bucharest to Paris, and her purse was discovered 5 km from the body. Her husband stated she would have been wearing a silver fox fur stole that was not found with the body. Although the death may have looked like a suicide or accident initially, these facts led the police to suspect foul play.

Three days following the discovery of the body, Farcasanu’s baggage was located in a check room in Basel, Switzerland, and all items of value had been removed. Police originally suspected Trajan Theodorescu, a swindler who targeted female Orient Express passengers, but he had an alibi during Farcasanu’s trip. Pawn brokers were asked to be on the lookout for the fox fur stole and a pricey wristwatch missing from her baggage.

Some time later, a Swiss detective name Karl Nievergelt noted a fur piece worn by a Sunday morning churchgoer. She stated it was a gift from her Hungarian student boarder, Karl Strasser. Strasser was arrested shortly thereafter and confessed to committing the crime for financial gain. Initially sentenced to death, Strasser’s fate was commuted to life in prison in 1937.

Two Unsolved Cases

Within the year after the publication of Murder on the Orient Express, a man’s body was discovered in a passenger car of a train as it entered a station in Cincinnatti, Ohio. A pair of shoes next to the body that did not belong to the man was the only clue to his mysterious death, and the crime was never solved.

In The Life and Crimes of Agatha Christie, Charles Osborne recounts the following:

On 3 May 1981, the London News of the World reported a murder in Bamberg, West Germany, which it called ‘a carbon-copy crime of Agatha Christie’s thriller, Murder on the Orient Express’. The method by which a sixteen-year-old girl was killed certainly suggested a knowledge of the novel or the film.

Unfortunately, this writer has been unable to locate additional information about this tantalizing case and encourages the reader to make contact if he or she can provide any details.

The Big One

Undoubtedly, the most notable true-crime case associated with Murder on the Orient Express is the one that inspired it: the kidnapping and murder of the Lindbergh baby, Charles Lindbergh, Jr. In what may be the actual Crime of the Century, the 20-month-old son of the famous aviator Charles Lindbergh and Anne Morrow (daughter of Ambassador Dwight Morrow) was kidnapped from his nursery on the evening of 01 Mar 1932. A ransom note was found on the radiator below the window of the room and demanded $50,000 for the safe return of the baby.

**At the time of the kidnapping, Anne Morrow was 7 months’ pregnant with her second child, which Christie paralleled with Sonia Armstrong in Murder on the Orient Express.**

The nation erupted. Charles Lindbergh was one of the most famous and highly regarded individuals at the time, having been the first aviator to cross the Atlantic Ocean in 1927. After the kidnapping, a popular song posed the questions:

Who stole the Lindbergh baby?
Was it you? Was it you?
After he crossed the ocean wide,
Was that the way to show our pride?
Was it you? Was it you? Was it you?

Despite the Lindberghs paying the ransom, the body of young Charles Lindbergh, Jr., was found on 12 May 1932. The extent of decomposition of the body suggested he was murdered very shortly after being kidnapped. During autopsy, the cause of death was concluded to be “fractured skull due to external violence,” but it was never known if this violence was accidental or intentional.

Prior to the Lindbergh case, kidnapping was not a federal crime. After the kidnapping of the Lindbergh baby, the US Congress passed the Lindbergh Law, which made it one.

An Inside Job?

An early theory of the police was that the kidnapping was an inside job. The Lindberghs had begun construction on an estate in Sourland, New Jersey in 1930. By 1932, the Lindberghs lived with Anne’s parents in Englewood, New Jersey, but spent weekends at the Sourland property. However, the family happened to be staying at Sourland the Tuesday night of the kidnapping. Police surmised that an inside source such as a member of the household staff may have inadvertently betrayed this to or were deliberately colluding with the kidnappers.

The police centered some of their investigation on Violet Sharp, a 28-year-old English maid. The staff had informed the police that Sharp had a date with an unknown man on 28 Feb. When she was interviewed on 10 Mar, the police reported Sharp was evasive and could recount no details of the man or the date. Additionally, Sharp’s sister, Emily, returned to England shortly after the ransom money had been paid without notifying the police of her travel plans.

Sharp was interviewed 3 more times, with each subsequent interview increasingly more invasive. The police interrogated Sharp regarding her relationships with men so forcefully that the fourth interview was cut short by an attending physician due to Sharp’s rapid pulse and high blood pressure. The following day, the investigators returned for a final attempt to speak with Sharp. Sharp refused to be interviewed and retreated to her bedroom with a measuring glass filled with powdered silver polish. In her desperation, she drank the polish (cyanide chloride) and died a short time later.

A total of 18 characters in 14 of Christie’s stories and novels died from cyanide poisoning.

To date, there has been no direct evidence linking Violet Sharp to the kidnapping and murder of Charles Lindbergh, Jr. Her travails are mirrored by the character of Susanne Michel (daughter to Pierre Michel) in Murder on the Orient Express.

Countess Andreyni (sister to Sonia Armstrong) recounted:

Poor Susanne? Yes, I had forgotten about her. The police questioned her. They were convinced she had something to do with it. Perhaps she had—but if so, only innocently. She had, I believe, chatted idly with someone, giving information as to the time of Daisy’s outings. The poor thing got terribly wrought up—she thought she was being held responsible.” She shuddered. “She threw herself out of the window. Oh it was horrible.”

Notably, Christie’s characters most directly based on individuals involved in the Lindbergh kidnapping (Susanne Michel and John, Sonia, and Daisy Armstrong) were only referenced by characters in Murder on the Orient Express and not active participants in the plot. This may have been done by Christie out of respect for the Lindbergh family.

A Promising Lead

Although the police devoted time and resources to characterizing Violet Sharp’s romantic relationships, the most valuable clues were uncovered immediately during their investigation: the ransom note and a hand-made ladder, custom built to reach the window to Lindbergh’s nursery. Police suspected that the ransom note left on the radiator was written by someone from Germany, given the placement of the dollar signs and the grammatical construction.

This note and the subsequent ransom notes were helpful to secure a conviction for one kidnapper, but the smoking gun in this case was the ladder found about 70 feet from the Lindbergh estate.

The examination of the ladder using forensic xylotomy, the tracing of the ransom money, and the conclusion of the Lindbergh case will be the focus of the next blog post.

Night Train to Perdition, Act I

Posted on April 11, 2020April 30, 2021 by Harley

”The impossible cannot have happened, therefore the impossible must be possible in spite of appearances.”

Hercule Poirot

Murder on the Orient Express, written by Agatha Christie in 1933 and published the following year, is perhaps her seminal work. It is certainly the most famous, with 2 notable feature film adaptations and references in “SCTV” and “Parks and Recreation” (to name a few). It is easy to understand the longevity of the work: a locked room mystery set on a glamorous sleeper train wherein “a repulsive murderer has himself been repulsively, and, perhaps deservedly, murdered.” But while the mysteries at the center of the story are neatly wrapped up by Hercule Poirot as he enacts his own interpretation of justice, fascination around the true-crime case that influenced the book persists to this day.

Christie's Train Journeys

Christie first traveled on the Orient Express in 1928, shortly after the divorce to her first husband Archie was finalized. She had met a Commander and Mrs. Howe at a dinner party in London, and they urged the author to visit Baghdad via the Orient Express. During this trip, Christie stayed at the Tokatlian Hotel in Constantinople before continuing on to the Middle East. It was through friends she made at an archaeological dig near Baghdad that she would meet her second husband, Max Mallowan.

**Christie’s time at archaeological sites with Mallowan inspired her novels Murder in Mesopotamia, Appointment with Death, and Death Comes as the End.**

Mallowan was a 25-year-old archaeologist at the dig at Ur the following year when Christie returned. The pair traveled together back to England after Christie received a telegram that her daughter was ill, and they formed a close friendship. Letters turned into visits, and Mallowan proposed marriage to the 38-year-old Christie. They were married on September 11, 1930. Christie wrote Murder on the Orient Express during her time at an archaeological dig at Arpachiyah with Mallowan in 1933. The novel is dedicated to him, and he has been credited with originally suggesting the solution to the mystery to Christie.

As with many of her novels, Christie drew inspiration from her own experiences and observations. Most notably, Christie’s travel via the Orient Express in December 1931 was delayed for 2 days as the result of a violent thunderstorm that had flooded the rail line. An American woman traveling is the obvious inspiration for Mrs. Hubbard in the novel; in a letter to Mallowan, Christie notes she exclaimed,

But why aren’t they doing anything? Why, in the States, they’d have motored some automobiles along right away – why, they’d have brought aeroplanes…

and

My daughter said I’d have no trouble at all – no trouble at all. I’ve never travelled to Europe before and I’ll never travel in it again.

During this journey, she also encountered two Danish missionaries, a Hungarian Minister and his wife, and a Director of the Wagon Lits Company, all of whom inspired other characters in the story.

All Aboard ... for Murder

Murder on the Orient Express is Christie’s 16th book and her 8th mystery with Hercule Poirot as the central detective. The novel begins with Poirot returning from Syria, where he has participated in some unspecified intrigue. He arrives in Istanbul, checking into the Tokatlian Hotel (where Christie herself stayed). After receiving a telegram recalling him to London, Poirot books passage on the Simplon-Orient Express. Surprisingly, the train is fully booked, but Poirot conveniently enlists the help of his friend M. Bouc, a director of the Compagnie Internationale des Wagons-Lits, to secure a second-class compartment.

While at the Tokatlian Hotel, Poirot first notices a brash and despicable American traveler. Regarding the man, Poirot tells Bouc,

I could not rid myself of the impression that evil had passed me by very close.

While aboard the Orient Express, Poirot again encounters this individual, who calls himself Ratchett and attempts to enlist Poirot’s help with a series of threats he has received. Poirot refuses, telling him,

If you will forgive me for being personal—I do not like your face, M. Ratchett.

That night, Bouc offers his first-class compartment to Poirot, which is adjacent to Ratchett’s on the Calais Coach. Shortly before 1 o’clock, Poirot wakes to a cry from the American’s compartment, followed by an explanation in French that “it was nothing.” Poirot has also noticed that the train has been stopped for some time. An older American woman, Mrs. Hubbard, rings her bell and reports loudly that a man has been in her compartment, which is adjacent to Ratchett’s on the opposite side as Poirot’s. Poirot asks the conductor for some mineral water and learns that the train is stuck in a snowdrift. He manages to fall asleep but is awoken later in the night with a loud knock on his compartment door; when he looks down the corridor, he sees a woman in a scarlet kimono walking away from his door.

After this eventful night, the talk in the dining car centers around the interminable delay of the train journey, until it is discovered around 10 o’clock that Ratchett has been stabbed to death. The crime scene has several clues; in addition to the presence of the burned remains of flat matches and a piece of paper, a pipe cleaner, and a fine woman’s handkerchief embroidered with the letter “H”, the window to the compartment is open but there are no tracks in the snow, and the dead man’s watch has been stopped at 1:15. Ratchett had been stabbed 12 times across the chest and abdomen. A Greek doctor staying in the Athens-Paris Coach, Dr. Constantine, assists with the examination of the body and states,

The blows seem to have been delivered haphazard and at random. Some have glanced off, doing hardly any damage. It is as though somebody had shut their eyes and then in a frenzy struck blinding again and again.

Poirot Investigates!

Of course, Poirot is enlisted to solve this mystery and sets about interviewing all the passengers of the Calais Coach:

Hector MacQueen: Ratchett’s young American secretary, who reports functioning more as a courier since the deceased knew no foreign languages; he describes the threatening notes received by Ratchett
Pierre Michel: The Wagon Lit conductor, deeply shaken by the crime on his train
Edward Henry Masterman: The English valet of the deceased, somewhat unaffected by the murder
Caroline Martha Hubbard: An elderly American woman, who reports there was a man in her compartment around the time of the murder and also provides the button from a Wagon Lit conductor’s uniform that appeared in her compartment. She later recovers the murder weapon, a bloody dagger.
Greta Ohlsson: A Swedish missionary, who was the last person to see Ratchett alive after mistakenly opening his compartment door
Princess Natalia Dragomiroff: An aged Russian princess, with no notable clues to report
Count Rudolph Andreyi: A Hungarian nobleman with little to report from the night of the murder
Countess Elena Andrenyi (née Goldenberg): The wife to the Count, who took a sleeping draught the night of the murder
Colonel John Arbuthnot: An English military officer, recently serving in India, who spoke with Hector MacQueen until nearly 2 o’clock the night of the murder
Cyrus Hardman: Traveling as a typewriting ribbon salesman, he reveals he is a detective from McNeil’s Detective Agency in New York enlisted by Ratchett for his protection. According to Hardman, the deceased man said he feared a small dark man with a womanish voice.
Antonio Foscarelli: An Italian automobile salesman based in the United States
Mary Debenham: An English governess previously working in Baghdad, who reports seeing the woman in the scarlet kimono but denies that it was her
Hildegarde Schmidt: The German maid to Princess Dragomiroff; she states she encountered a Wagon Lit conductor who was not Pierre Michel and was a small dark man with a womanish voice. She also seems to recognize the handkerchief found in the deceased man’s compartment.

Additionally, Poirot manages to ascertain the identity of the murdered man using the burned note fragment at the crime scene and some hat boxes. Ratchett was in truth the notorious American criminal, Cassetti, who was responsible for the kidnapping and murder of Daisy Armstrong. Daisy was the daughter of Colonel and Sonia Armstrong; she was abducted from the family’s home with a ransom demand for $200,000. After the ransom was paid, Daisy’s body was found, and it was evident that she had been dead for some time.

Mrs. Armstrong was pregnant at the time and gave premature birth to a still-born child; the mother died during childbirth. Colonel Armstrong, devastated at these compounded losses, died by suicide. Furthermore, Daisy’s French nursemaid, Susanne, was suspected of assisting in the crime and also died by suicide, though her innocence was subsequently proven. Cassetti was apprehended and charged with the crime, but due to his wealth and connections, he was acquitted on a technicality. He escaped from America. Christie drew obvious inspiration from the kidnapping and murder of Charles Lindbergh, Jr, which occurred the year before she wrote the novel.

Through his inquiries, Poirot manages to prove a connection between each of the passengers and the Armstrong case. In a stunning denouement, he reveals two potential solutions to the passengers when they are assembled in the dining car later in the day following the murder.

The first solution is that a stranger boarded the train after it departed Stamboul and used a Wagon Lits conductor uniform and pass key to enter Ratchett’s compartment–these items had been found in the luggage of Hildegard Schmidt during a search of the Calais coach. The stranger stabbed Ratchett and escaped into Mrs. Hubbard’s compartment, which is supported by Mrs. Hubbard sensing a man in her compartment and finding the missing button of the Wagon Lits conductor uniform. The stranger then escaped the train before it departed from the last station; the inconsistency in the time of the crime versus Ratchett’s watch may be explained by the deceased forgetting to adjust his watch when entering the Central European Time Zone.

One notable reveal by Poirot is that the “H” on the handkerchief is from the Cyrillic alphabet, corresponding to an “N” in the Latin alphabet, and therefore belongs to Natalia Dragomiroff. A similar device is used in Christie’s short story The Double Clue as well as in Season 11, Episode 11 of Murder, She Wrote (“An Egg to Die For”).

Several of the passengers (most vociferously M. Bouc and Dr. Constantine) note that this explanation fails to account for several small details of the crime. Poirot then recounts his second–and correct–solution. Every passenger in the Calais Coach on the night of the murder, save himself, had some connection to the Armstrong case. Conspiring together with Mrs. Hubbard–mother to Sonia Armstrong–as the ringleader, they decided to carry out a death sentence on the criminal during this journey on the Simplon-Orient Express. Twelve passengers (with the Count Andreyni standing in for his wife, Sonia Armstrong’s sister) stabbed Cassetti after Masterman had drugged his sleeping draft; like a firing squad, the death could not be ascribed to any one participant.

Faced with the two possible solutions, Poirot allows Bouc to decide which will ultimately be reported to the Yugoslavian authorities. The Director elects the former solution of a stranger boarding the train to commit the murder. Poirot accedes and “has the honour to retire from the case.”

Reception and Film Adaptations

Murder on the Orient Express remains one of Christie’s most popular works and has been present in the zeitgeist since its publication. The novel has been adapted into 2 noteworthy feature films. While the 1974 version is fairly loyal to the source material, the 2017 version departs quite a bit and will not be further discussed.

Following the Miss Marple films released in the 1960s, Christie was hesitant to grant the film rights for any more of her work. It required some delicate finagling by Lord Louis Mountbatten, a naval hero and father-in-law to British film producer John Bradbourne. Eighteen months later, Christie granted the film rights to EMI. The resulting film, directed by Sidney Lumet, has an all-star cast and employed genuine Orient Express train cars on loan from the Compagnie Internationale des Wagon-lits Museum in France. At the age of eighty-four, Christie attended the movie premiere and appreciated the film. The adaptation became the highest grossing British film for a time.

While it is certainly an enjoyable–if improbable–story, part of the endurability of Murder on the Orient Express must be credited to the contemporary true-crime tale of the kidnapping and murder of Charles Lindbergh’s child. The original Crime of the Century parallels the tragic story of Daisy Armstrong and will be explored (in addition to some other related true-crime stories) in the next post.
