The Locked Room Mystery

The locked room mystery is a sub-genre of detective fiction where a crime has been committed in a location where no suspect could logically have committed the crime. The typical locked room mystery involves a scene where, for example, the victim is shot to death inside a totally sealed room and suicide is logically impossible. Cases of poison are usually excluded, as in the case of Christie’s ‘Mysterious Affair at Styles’, since the means of murder may have occurred prior to entering the chamber, or have been previously inserted into the room in the form of tainted drinks or food. The same rule generally applies to any obvious mechanical device or booby trap. In a true locked room case, the murder must appear to have been completely executed behind closed doors by an unknown suspect.

Impossible CrimesMany mystery buffs include ‘Impossible Crimes’ in the Locked Room sub-genre, though this is actually a separate sub-genre. Impossible crimes include all those cases, so common in the Golden Age of Detective Fiction, where the murder, for example, is committed right in front of an entire room of witnesses, none of whom are able to understand how the deed was done. While this site concentrates on the locked room story, in many instances it is extremely difficult to draw a clear line between these two related plot lines, often written by the same authors, so we will therefore also include many ‘Impossible Crimes’ in these pages, especially when written by authors of Locked Room mysteries, and leave it to the reader to decide on the appropriate classification. 

The true locked room mystery, which remains our central focus, may be fairly clearly defined by three basic rules – which would hold, at a minimum, that:

1) The victim is apparently alone at the time of the murder, or the murderer impossibly disappears after committing the crime. At the very least, the victim must appear to be beyond the reach of any logical  method used by the suspect to commit the murder and then make good his escape.

2) No suspect could have logically committed the crime using the apparent method of murder.

3) There is no obvious manner in which poison, a booby trap, or a secret passage, could have been prearranged. Booby traps and secret passages are never found in the best examples of the Locked Room sub-genre!

In many instances, following the usual conventions of classic detective fiction, the reader is presented with this seemingly impossible situation, and all the clues, then provided with a ‘fair play’ challenge to solve the mystery before the solution is revealed in a dramatic climax.

In some ways, the Locked Room mystery is closely associated with all those classic gothic tales of the supernatural, as it often appears that only a ghostly presence could be responsible, though this conclusion is inevitably viewed as superstition, which the rational detective soon reveals to be pure illusion. The real mystery of a Locked Room story is therefore not usually the ‘whodunit’, as that is clearly secondary to the primary ‘howdunit’ explanation. It is the search for a logical solution, which drives the protagonist to ignore the distraction of the appearances and solve the puzzle.

Rue Morgue 2The mystery genre was not truly established until the late 19th century, though there are a number of earlier works which provide the origins of the modern murder puzzle. This history is more fully explored in our, ‘Origins of Mystery Fiction’ page. In the specific case of the Locked Room mystery, the deuterocanonical Old Testament story, Bel and the Dragon, is often viewed as one of the primary influences, as well as the 5th century BC tale from Herodotus, King Rhampsinitus and the thief, which tells of a thief whose headless body is found in a sealed stone chamber. Honoré de Balzac and Alexander Dumas are also given some credit, but the real originator of this sub-genre is Edgar Allan Poe, in his classic tale ‘The Murders in the Rue Morgue’, published in 1841. Wilkie Collins 1868 work, ‘The Moonstone’, also employs many elements of the  locked room murder, as do several stories by Joseph Conrad and Sheridan Le Fanu, who concentrated on secret passages and other similar devices. Still, it was Big Bownot until Israel Zangwill’s 1892 story, ‘The Big Bow Mystery’, that the idea of ‘misdirection’, a purposely created illusion by the criminal, became the central device of most Locked Room mysteries. This was soon followed by several of the Sherlock Holmes stories, especially ‘The Adventure of The Speckled band’ (1892), which  clearly popularized this new sub-genre. The Locked Room mystery also proved extremely popular in France, following the publication of “The Mystery of The Yellow Room’ (1907) by Gaston Leroux, which led to several French authors writing popular Locked Room novels, many of which have never been translated into English.

mesopotamiaWith the arrival of the Golden Age of Detective Fiction, locked room and impossible crime stories became a common part of the immensely popular mystery craze, with most of the great authors of this age, including G.K. Chesterton, Agatha Christie, Dorothy L. Sayers, Ngaio Marsh, Edgar Wallace, Michael Innes, Margery Allingham, Georgette Heyer, Ellery Queen, S.S. Van Dine, and many others, trying their hand at Locked Room plots. The Locked Room Mystery will try to sort out the best representatives from this massive list of potential titles. Most of these murders were solved by amateur sleuths, or Scotland Yard detectives, through a chain of brilliant deductive reasoning.

hollow manHowever, there were also a select group of authors who clearly specialized in this new sub-genre, with John Dickson Carr (aka Carter Dickson), Christiana Brand,  Jacques Futrelle, Edmund Crispin, Clayton Rawson, Edward D. Hoch, and Hake Talbot leading the pack. Still, there really can be no doubt that the true ‘King of The Locked Room Mystery’ was John Dickson Carr (aka Carter Dickson), who created an entire library of excellent Locked Room mysteries, many featuring either Dr. Gideon Fell, or Sir Henry Merrivale, in  a fascinating array of imaginative tales, that will likely never be equalled in a modern world that seldom finds the time to sit down and read a good murder.

Fourth DoorIn France, the Locked Room also flourished. This time the king was Pierre Boileau, with serious efforts by Thomas Narcejac, Gaston Boca, Marcel Lanteaume, and Noel Vindry. After the Second World War, the Locked Room mystery waned in the English market, but continued in France with Paul Halter leading the way, and was later adopted by several Japanese writers. The English genre made a bit of a comeback in the 1970’s with some of Bill Pronzini’s novels, and the masterful short story collections of Edward D. Hoch, especially those featuring Dr. Sam Hawthorne, a country physician and amateur detective.

In recent years this sub-genre has waxed and waned, but still continues to produce some of the best works in modern mystery fiction. Sit down and lock yourself into a really impossible mystery!

The Hollow Man, also published as ‘The Three Coffins’, has been voted the best locked room mystery ever by a group of mystery authors and critics organized by Edward D. Hoch. 

Professor Charles Grimaud and his friend are meeting at tavern when they are interrupted by a stranger who claims that men can arise from their graves and walk through walls. This odd character is illusionist Pierre Fley, who claims to have done these things himself, then adds that he has an even more dangerous brother who wants Grimaud’s life. Grimaud must choose which brothers he wants to call on him, and Grimaud angrily invites him to send his brother and be damned.

On the appointed night, Grimaud awaits his anticipated visitor. The visitor arrives, wearing a mask, and is escorted to the study. Two witness sees Grimaud let the stranger enter and close the door, and both continue to observe the door until shots are heard inside the room. The locked door is finally broken down, to reveal a dying Grimaud, but no stranger or weapon can be found, and the yard below the only window is covered with a pristine untrammelled blanket of snow.

That same night, two men and a police constable witness Pierre Fley walking alone down a deserted cul-de-sac, then hear a ghostly voice shout “The second bullet is for you!” – followed by a gunshot. Fley is found shot in the back at very close range, with the revolver that killed both victims at his side – and once again there are no tracks in the snow that surround his body. It is clearly a case for Dr. Fell!

Locked Room Review

Book  eBook  CD  Movie/DVD

A wealthy publisher and collector of precious stones and Chinese postage stamps lives in a luxurious hotel suite that doubles as his office for business that is not related to Mandarin Press. The hotel is also the centre for the comings and goings of Donald Kirk’s staff, his relatives, and his female friends. The mystery begins when an odd, anonymous man arrives and refuses to state his business to Kirk’s clerk, James Osborne. He is led into an anteroom with a bowl of fruit (including tangerines, also known as Chinese oranges) to await the publisher’s arrival.

However, when Kirk finally returns and is advised that the man is still waiting, the door connecting to the office is found to be locked, and a truly bizarre scene is displayed inside. The victim’s skull his broken, his clothing is reversed, back to front, all the furnishings of the room have been turned backwards — and two African spears have been inserted between the body and its clothing. The only other entrance to the room was more or less observed, and it seems quite impossible that anyone could have entered and had sufficient time to arrange this fantastic scene. The mystery is made more complex by some valuable jewelry and stamps, the publisher’s business affairs and romantic affaires, and an apparent connection with “backwardness” for every character. Ellery Queen must first sort through all the motives and discard the lies and misdirections, before he finally arrives at an amazing solution to this confounding puzzle.

Even a brief review of the number of talented authors whose careers began with being published in this magazine is quite remarkable.

Best Review

Book  eBook  CD

The young lady had just retired to her room when sounds of a struggle ensue, and cries of “Murder!” and revolver shots ring out. When her locked door is finally broken down by her father and a servant, they find the woman on the floor, badly hurt and bleeding. No one else is in the room. There is no other exit except through a barred window. How did the attacker escape?

First published in 1907, this intriguing and baffling tale is a classic of early 20th-century detective fiction. At the heart of the novel is a perplexing mystery: How could a crime take place in a locked room which shows no sign of being entered? Nearly a century after its initial publication, Leroux’s landmark tale of foul play, deception, and unbridled ambition remains a blueprint for the detective novel genre. 

“The finest locked room tale ever written.” — John Dickson Carr, author of The Hollow Man.

His novel The Mystery of the Yellow Room is one of the original Locked Room novels, contemporary with the Sherlock Holmes stories, and Israel Zangwill. Originally published in French in 1907,  it is truly a must read Locked Room classic!

Theater companies are notorious hotbeds of intrigue, and few are more intriguing than the company currently in residence at Oxford University. Center-stage is the beautiful, malicious Yseut, a mediocre actress with a stellar talent for destroying men. Rounding out the cast are more than a few of her past and present conquests, and the women who love them. And watching from the wings is Professor Gervase Fen, scholar, wit, and fop extraordinaire, who would rather solve crimes than expound on English literature. When Yseut is murdered, Fen finally gets his wish. Gilded Fly, originally published in 1944, was both Fen’s first outing and the debut of the pseudonymous Crispin (in reality, composer Bruce Montgomery).

The Moving Toyshop
Swan Song

Edmund Crispin was actually the pseudonym of Robert Bruce Montgomery (1921 – 1978), who is remembered for both his Gervase Fen mystery novels and his musical compositions. Born in Chesham Bois, Buckinghamshire, Montgomery graduated from St John’s College, Oxford, in 1943, with a BA in modern languages. He also spent two years as this school’s organ scholar and choirmaster – a position which plays a central role in ‘The Gilded Fly’. He first became known for his mysteries and was only later recognized as a composer of vocal and choral music, including ‘An Oxford Requiem’ (1951). He eventually turned to film work, writing the scores for many British comedies, including the famous ‘Carry On’ series. Montgomery also authored the screenplay and score of ‘Raising the Wind’ (1961).

The novels of Edmund Crispin continue the development of the sophisticated literary style of mystery that largely began with Dorothy Sayers, and also attempt to continue the device of a professorial detective investigating impossible locked room mysteries, in a nod to John Dickson Carr’s, Dr. Fell.

Book  eBook

‘Whistle Up The Devil’ is one of the most famous locked room masterpieces of all time. It introduces Algy Lawrence, a brilliant young man who has already worked with the police as an amateur sleuth prior to this appearance.

The plot hinges on a “family secret”, passed from father to son, a month before the son’s wedding, within the Querrin family. This secret concerns a room within the family residence, called “The Room of Passage“, which has been the scene of an old tragedy.

On this occasion, the secret is passed from Peter Querrin to his son, Roger, who is engaged to Audrey. Roger decides to revive, and finally discredit, this old family tradition. He will “blow the whistle to the Devil” by spending a night in the haunted room. Four men stand on vigilant guard, making it quite impossible for anyone to enter – but at midnight Roger is still stabbed with the same dagger that was used in the family legend – and a second locked room mystery soon follows.

More on ‘Busman’s Honeymoon’

The daughter of an English clergyman, Dorothy Sayers was born at Christ Church Cathedral in Oxford in 1893 and grew up in the rather pleasant rural parish of Bluntisham-cum-Earith in Huntingdonshire. In 1912 she won a scholarship to Somerville College, Oxford, and later became one of the first women to receive a degree from Oxford. She worked for a time in advertising, lectured and wrote poetry, wrote several popular works on the Christian faith, and considered her translation of Dante to be her greatest acheivement. As part of ‘The Socrates Club’ at Oxford, she was close friends with C. S. Lewis and J.R.R. Tolkien, while as a founding member of The Detection Club, she associated with most of the great authors of the Golden Age of British mystery fiction.

Sayer’s first Lord Peter Wimsey novel, ‘Whose Body?, was released in 1921, and proved to be immensely popular. The Lord Peter stories, complete with his love of rare books, his struggle with shell shocked nerves, the ever dependable Bunter, his ambiguous feelings about the consequences of amateur sleuthing, and the long tangled history of his relationship with Harriet Vane,  are all brought to a final conclusion in this amazing locked room story.

The role played by Sherlock Holmes and Sir Arthur Conan Doyle in the developments of the mystery genre should never be underrated.

Margery Louise Allingham (1904 – 1966) was an English writer of detective fiction, best remembered for her “golden age” stories featuring gentleman sleuth Albert Campion.

Allingham’s breakthrough came in 1929 with the publication of ‘The Crime at Black Dudley’. This introduced Albert Campion, though only as a minor character. He next appeared in Mystery Mile, at the instigation of her American publishers. Allingham’s skills continued to improve, and with Campion’s popularity growing, she began to produce a 17 novel series, while continuing to write short stories and non-fiction for The Strand Magazine and other publications.

Book  eBook

Remington Cara, an extremely wealthy Greek, is afraid of being murdered in his bed, so he builds a burglar proof bedroom, yet still ends up dead. Assistant Commissioner, T. X. Meredith, is given the job of figuring out how this impossible crime was committed. One of the better Edgar Wallace novels, a little over dramatic with some awkward dialogue, but still a good read.

Richard Horatio Edgar Wallace (1875 – 1932) was an English writer. Wallace was born ‘illegitimate’ and raised in extreme poverty London. His schooling ended at age 12, and he later joined the army, before becoming a war correspondent during the Second Boer War. Badly in debt, he began to write penny dreadfuls as an easy way to quickly raise funds. Wallace used his experiences as a reporter in South Africa and the Congo, covering the Belgian atrocities, as the foundation for several of his early works. Wallace serialized short stories in several magazines, before finally signing with Hodder and Stoughton in 1921, where he became an internationally recognized author.

More on ‘Envious Casca’

Georgette Heyer (1902 – 1974) was an English historical romance and detective fiction novelist. Her writing career began in 1921, when she turned a story for her younger brother into the novel ‘The Black Moth’. In 1925 Heyer married George Ronald Rougier, a mining engineer, and spent several years living in Tanganyika Territory and Macedonia before returning to England in 1929. After her novel ‘These Old Shades’ became immensely popular despite its release during the General Strike, Heyer determined that publicity was not necessary for good sales and continued to refuse all requests for interviews.

Heyer essentially invented the historical romance genre and its subgenre Regency romance. Beginning in 1932, Heyer released one romance novel and one thriller each year. Although many critics describe Heyer’s detective novels as unoriginal, others such as Nancy Wingate praise them “for their wit and comedy as well as for their well-woven plots”.
