Old man Wayne is about to read his will, All of the heirs are gathered. When his secretary and nephew makes a run at stealing, replacing and re-stealing a valuable gem Wayne calls the police. After the police arrive Wayne tells them to wait while he goes to tell the heirs just what he thinks of them. However before that can happen the old man keels over and dies. When he's lifted up a knife is sticking in his chest. More police are called and a detective (soon to be aided by a smart mouth reporter) tries to solve the crime. Good mystery is hampered by the lack of music (this was 1932 and many independent producers didn't use it) this movie is a slow go for the first half. Once things get moving its a good ride to the end with almost all of the suspects coming under suspicion and the sudden appearance of a dark robed figure trying to kill off the heirs. As the story progresses and more murders occur there are a couple of nice pre-code touches as we rather graphic hanging as well the the graphic end of the killer. Worth a look if you run across it.
