Dangerous Masquerade (1939)

A down-and-out writer being hounded by collectors stumbles upon dead man lying under a fallen tree limb. Little did he know the man had been murdered, and he concocts a scheme of exchanging clothes and identifications in hopes of making a clean slate of things. Coincidental happenings lead the police to his new alias. A secret diary and a murder weapon hold the truth to his innocence while Scotland Yard is now the hound on his trail. The true killers are eventually exposed to him and his sweetheart. Then the truth is exposed. A somewhat frustrating story as the viewer watches errors in judgement from all angles. But a good ending for all except the murderers.
