From The Perry Mason TV Show Book
When Franklin Shore, a man dead ten years, telephones his niece, Helen, giving her instructions on how to meet him, things are just beginning to get spooky.

Perry must not only find out where the dead man was calling from, but also: Who killed Henry Leach, a man who was blackmailing the deceased? Who took a shot at Helen’s boyfriend, Frank? Who poisoned the deceased’s wife, Matilda? And who poisoned Monkey, the cat?
