That dashing Errol Flynn plays Francis Monroe Warren II, an upper-crust investment counselor that lives a double life away from his high society...rubbing elbows with the police and secretly writing crime novels under a pseudonym. His recent book Footsteps in the Dark, seems to be ruffling the feathers of the elite; and his own mother hires someone to try and find out who is doing this writing. His wife(Brenda Marshall)thinks he spends a lot of time at night at stuffy board meetings; while he is actually investigating current crimes and trying to debunk the theories of local police. Francis even becomes the subject of interest in a murder over a fortune in jewels. The pace is brisk and you have to be quick to catch some of the humor. In support are: Alan Hale, William Frawley, Roscoe Karns, Lee Patrick and Lucile Watson.
