"The Criminologists' Club" is a short story by E. W. Hornung, and features the gentleman thief A. J. Raffles, and his companion and biographer, Bunny Manders.

[2] It was also included as the fourth story in the collection A Thief in the Night, published by Chatto & Windus in London, and Charles Scribner's Sons in New York, both in 1905.

However, on the night of the dinner, Bunny overhears the whispers of two members, and discovers that the club in fact suspect Raffles to be a gentleman thief.

At dinner, Raffles and the four men, including a Wild West novelist and a barrister who has sentenced criminals to death, amiably discuss convicted murderers and burglars.

Eventually, Lord Thornaby mentions their belief that the same thief committed the burglary on Bond Street and the robbery of Lady Melrose's necklace.

Lord Thornaby asks his butler to fetch an emergency rope-ladder, and the novelist bravely climbs down and opens the dressing-room door.
