Edgar Jepson & Robert Eustace
The Tea-Leaf by Edgar Jepson & Robert Eustace

The death-causing method is ingenious. A lesson in applied science. It is such a fascinating method that the basic idea has subsequently been copied by other authors.

Two former friends, who had a falling out and now hate each other, meet in a Turkish bath. A verbal altercation ensues. One exits and goes to the shampoo room and the other is found dead. No weapon is found and the possibility to smuggle in and out a weapon has been ruled out by the available evidence. The living man, the apparent criminal, is charged with murder and it takes the genius of the victim's daughter to prove him...

Arthur Conan Doyle
The Lost Special by Arthur Conan Doyle

The word 'special' in the title refers to a special train - a privately hired train. This is a train a railway company inserts into its regular schedule when somebody pays for the expenses of the locomotive, wagons, and staff to operate the train. It is essentially the equivalent of chartering an airplane at a time when there were no airplanes.

This impossible crime story concerns the baffling disappearance of a special from the London and West Coast Railway Company on its journey from Liverpool to London on 3rd June 1890. Besides the train crew of driver, fireman, and train guard the only...

Max Rittenberg
The Invisible Bullet by Max Rittenberg

... and four other Magnum, the science consultant, detective stories.

Each story has a scientific bend or aspect to it. Magnum is not the typical detective who takes on any interesting case. He only engages when there seems to be a scientific aspect to the case. He doesn't involve himself with the law or right or wrong. His primary interest is to figure out the modus operandi as a scientific consultant. Superbly eccentric, Magnum lives up the Thames at Plumstead Marshes and travels to his laboratories via a high-powered motor launch named "Fifi". He has a brilliant but intensely shy assistant,...

J. C. Cannell
100 Mysteries for Arm-Chair Detectives by J. C. Cannell

Based on actual crimes and mysteries investigated at Scotland Yard.

This is a fun read if you like short problems of deduction and observation. While most of them are not locked room problems, there are two of them in this collection, #34 and #88. One of them states that on an express train, a girl was found dead in a third-class compartment. Her head was badly injured. A violent blow had caused her death. The train had not stopped during the journey and the girl had occupied the compartment alone all the way.

Magicians will be able to solve some of the mysteries more easily because they...

Walter S. Masterman
The Wrong Letter by Walter S. Masterman

The crime: The Home Secretary Sir James Watson was found shot in the head inside his study which was locked from the inside. There was no apparent way in or out for the murderer to have been able to get into the room to commit the crime, nor a way to escape unnoticed. Further, the housekeeper Mrs. Simmons did not hear any shot which she certainly would have. What is going on here? How was the crime committed and by who?

It will be the task of Superintendent Sinclair from Scotland Yard and his amateur sleuth friend Sylvester Collins, a barrister, to unravel the mystery.

Jacques Futrelle
The Problem of Cell 13 by Jacques Futrelle

The premise of this locked-room story is wonderful. The protagonist is Augustus S. F. X. Van Dusen who is in a scientific debate with Dr. Charles Ransom and Alfred Fielding. Augustus, also known as "The Thinking Machine", claims that nothing is impossible when logic and clear thinking are applied. To prove his point, they conduct an experiment where Van Dusen is locked up in a prison for one week with the challenge to escape, which of course he does. But the real fun is in how he does it. It is a tour de force of logic and deductive thinking. Highly recommended to all locked room crime lovers. ...

Arthur Conan Doyle
The Adventure of the Empty House by Arthur Conan Doyle

Arthur Conan Doyle was the most famous and successful author in the detective story genre. One of the locked-room mysteries he wrote was The Adventure of the Empty House. The story plays in 1894, three years after Holmes's apparent death. Ronald Adair, son of the Earl of Maynooth, a colonial governor in Australia, was killed with a soft-nosed revolver bullet to his head while sitting in his room, working on accounts of some kind. The motive was not robbery since nothing was stolen. Adair's door was locked from the inside and the only window in the room presented a 20-foot drop with no sign...

Israel Zangwill
The Big Bow Mystery by Israel Zangwill

The Big Bow Mystery was one of the first locked-room mystery stories and the first full-length locked-room mystery. It is still one of the best with an ingenious solution. It has been used as the basis for three movies (The Perfect Crime (1928), The Crime Doctor (1934), The Verdict (1946)).

Set in London's East End, in Bow, a murder occurred inside a locked room, with no clear indication as to the weapon used, the perpetrator of the crime, or a possible escape route. Mrs. Drabdump, a widow who rents out rooms, panics when one of her lodgers does not respond to her attempts to wake him....

Edgar Allan Poe
Murders in the Rue Morge by Edgar Allan Poe

With Murders in the Rue Morge, Edgar Allan Poe is the inventor of the model for the modern detective story consisting of a brilliant detective, his personal friend who serves as the narrator, and the revelation of whodunit that is revealed before the explanation of how the crime was committed. More specifically, Poe is also the father of the locked room mystery, detective stories where the impossibility of the crime takes center stage. Sir Arthur Conan Doyle acknowledged that he modeled his most famous Sherlock Holmes stories after Poe's detective story model by having Watson explicitly state in the first Holmes...
