Carter Dickson

The diplomat Sir George Ramsden is returning to Britain from France with the mysterious "unicorn" in tow. The legendary thief Flamande has declared that he will be on the same flight as Ramsden, in disguise, and that the unicorn will be his. His arch-rival and head of the Srete Nationale, Gasquet, has assured the public that he too will be on the plane to thwart his nemesis. Meanwhile, holidaying in Paris, the ex-spy Kenwood Blake runs into Evelyn Cheyne and is swept into a perilous chase ending at the Chateau de l'Ile on a stormy night. Here, Ramsden's plane has made an emergency landing, and Henry Merrivale has joined the party. When the castle is cut off by the flooding river, the stage is set for a battle of wits between two masters of disguise in Flamande and Gasquet, as a bizarre and seemingly impossible murder among the party casts suspicion in every direction and the mystery of the unicorn is revealed. Carter Dickson's brilliantly intricate mystery was first published in Britain in 1936; it remains a testament to his unique talent for wrangling audacious levels of devilishness into a masterpiece.

One of the greatest locked-room murder mysteries of all time, hailing from 1938, returns to baffle a new bevy of armchair detectives. James Answell, visiting his father-in-law Avery Hume in his locked study, has the misfortune to wake up from a drugged-Whisky swoon to find his host dead, skewered with an arrow. He is, of course, prime suspect. After setting up this devilish scenario, unravels an ingenious courtroom thriller, in which the razor-sharp amateur detective (and barrister) Sir Henry Merrivale stars in all of his outlandish glory - and the mystery of the 'Judas Window' is revealed.

"There will be ten teacups at number 4, Berwick Terrace, W. 8, on Wednesday, July 31, at 5 p.m. precisely. The presence of the Metropolitan Police is respectfully requested."Writing as Carter Dickson, the master of the locked room mystery John Dickson Carr returns to the Crime Classics series, pitching his series amateur detective Henry Merrivale against a seemingly watertight mystery: after the police are sent a note warning them about a forthcoming crime, a man is shot in a room on the top floor of a Kensington townhouse a house watched from all sides during the murder. Surely nobody could have gotten in or out? And yet the man is dead, and just like the last time the police received a note like this, there are ten teacups set out at the scene of the crime. H.M. is drawn to unravel this bizarre crime, as the mysterious significance of the ten teacups in murders past and present pushes the police to their limits.
