The Criminologists' Club is a short story by Ernest William Hornung featuring A.J. Raffles from the 1905 collection A Thief in the Night.
Raffles encounters a society of crime experts, who call themselves The Criminologists'. They take an interest in a number of crimes, especially the series of jewell robberies that have blighted London society. Raffles and his friend Bunny Manders are invited along obstensibly to discuss the potential of crime in sport (such as gambling and throwing off matches), as Raffles is a well-known cricketer. However, the club have in fact got their eye on Raffles as the notorious gentleman thief.
When the Raffles stories were adapted for British teleivision in 1977, this story was merged with another The Jubilee Present to create a single episode The Gold Cup.
