Anthony Ruthven Gethryn is a character depicted in novels by Philip MacDonald and their cinematic counterparts.
History
Gethryn is the series detective for more than a dozen of Philip MacDonald's murder mysteries, written between 1924 and 1959. He is an amateur detective who works closely with the police to pursue criminals.
In Macdonald's first Gethryn novel, The Rasp, Gethryn is presented as a British ex-secret service agent and newspaper reporter, who solves an intricate locked room mystery and meets his future wife.
Adaptations
Gethryn was portrayed by Claude Horton in the 1932 film version of The Rasp.[citation needed]
The 1956 film, 23 Paces to Baker Street, based on the 1938 Gethryn novel, Warrant for X, conflates Gethryn's character with that of the playwright who overhears the conversation which triggers the plot. Van Johnson plays the role of Phillip Hannon, the blind playwright/detective.[citation needed]
