Plot: loose adaptation of the Buchan espionage thriller. Colonial Richard Hannay finds himself embroiled in a melodramatic spy story - is pursued to the Highlands of Scotland blamed for a murder he didn't commit - stumbles into the den of a German master spy who tries to kill him - gets handcuffed to an attractive blonde - uncovers the mystery of the 39 Steps at a finale at a London Music Hall.

Has Hitchcock's fingerprints all over this film. Good interplay between the leads. Restrained and effective playing by the support characters. Neat set pieces. Filmmaking that works.
