Slim Callaghan

Slim Callaghan is a fictional London-based private detective created by the writer Peter Cheyney. Like another of Cheyney's characters, the FBI agent Lemmy Caution, he was constructed as a British response to the more hardboiled detectives of American fiction such as Sam Spade and Philip Marlowe.

After making his debut in the 1938 novel The Urgent Hangman he featured in six further novels and a number of short stories. The novels were all bestsellers. The character has also appeared in a variety of film, television, radio and stage adaptations. The novels enjoyed particular popularity in France where actor Tony Wright played Callaghan in three film adaptations. Other actors to portray Callaghan include Michael Rennie, Derrick De Marney and Viktor de Kowa who played him in the 1964 German television series Slim Callaghan Intervenes.

Operating out of an office in Mayfair's Berkeley Square he frequently encounters attractive, but deceitful femmes fatales. Callaghan has been described as a "suave, handsome, resourceful, Mayfair-based private detective who is Irish – the nationality was perhaps a tease for Cheyney's patriotic critics".
