If you think the goofy-sounding title bodes ill for the film you're probably not far wrong. This story has some reasonably Agatha Christie-esque moments, but despite being the only one of the Inner Sanctum Mystery series to actually have Lon Chaney be the killer, it is also one of the least-well constructed (and the one that gives Chaney the least screen time). Not so surprising is that this is the final installment in that series. The ending has the next-door neighbor who has been stalking Brenda Joyce's character win her hand, without any indication throughout the film that she looks at him as anything but a creep. Meanwhile, Lon Chaney, who has for most of his screen time been the nice guy who Joyce seemed meant to be with, is dragged off to prison or an asylum. Now that's rotten plottin'.
