The boomerang of a Mexican divorce and the threat of bigamy provides Perry Mason with a fine tangle to finagle. Peculiar business doings, the murder of the first wife, and Mason, out of his own bailiwick, demonstrates that what is all right for the police to do is illegal when some one else beats them to it, that he can take it as well as dish it out, and fireworks to a stellar ending. Beautiful babes, worthy opponents and fancy legal cross-stitching.
