This is the worst of the Falcon series. There's not a shred of mystery and suspense. The comedy is lame except for Keye Luke's bits. Why confine Sanders to a bed with a concussion and never have him and real life brother Tom Conway work together to solve a mystery is an unforgivable omission by the writers. I don't know their personal history or if there was a conflict. Both brothers were masters at playing easygoing, extremely bored, well-dressed, disdainful sophisticates. Sanders had the edge on Tom in that department. Jane Randolph with her smart sex appeal provides the only spark in this dry timewaster.
