Fast Company

This is a comedic detective story in the vein of the Thin Man movies.  Melvyn Douglas plays a rare book dealer who dabbles in book related detective work, along with his wife/secretary (Florence Rice). This movie spawned two sequels in 1939, each with different actors playing the lead.

Familiar faces: Thurston Hall (TV's Topper) and Nat Pendleton, who got surprisingly high billing considering he's only in two short scenes.
