This film's excellent cast brings interest to a story of otherwise routine family events. Almost all of the performers are nicely matched with their characters, especially William Powell and Irene Dunne as the parents.

Archer Coe has been found dead in his locked bedroom. The cops consider it suicide, but Philo believes otherwise. When the Coroner shows up, he finds that Archer had been hit with a blunt object, stabbed and shot - making suicide unlikely. When the evidence points to his brother, Brisbane is found stabbed to death in the closet. Archer had a number of enemies, any one of which would have been glad to knock him off, but which one did and how did the murder occur in a room looked from the inside.

Philo Vance investigates one of his most famous locked-room murders.

The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.

A ditzy socialite finds a homeless man for a scavenger hunt and then hires him as their butler.
