Venerable character actor Ferdinand Gottschalk dominates the proceedings in the Universal crime meller Secret of the Chateau. The plot is set in motion by a rare Gutenberg bible, much coveted by a variety of thieves and mountebanks. Chief Inspector Marotte (Gottschalk) is anxious to capture an elusive book bandit named Prahec, whom he's never seen but who could be any one of a number of suspects. Practically everyone in the cast converges on the titular chateau, where two murders occur. Methodically, Marotte sifts through the suspects and fingers the killer, who of course is revealed to be mysterious Prahec. Former silent-screen leading lady Alice White provides several amusing moments as an overly flirtatious suspect.
