The Case of the Howling Dog

"When a potential client wants to see Perry Mason about a howling dog and a will, the attorney is not interested. He does not enjoy drawing wills, and wonders if the man shouldn't see a veterinarian. However, when the man asks whether a will is legal if the person who made it had been executed for murder, immediately Mason becomes interested. He finds, in addition to the will and the dog, a man who had run away with the wife of another, and a sexy housekeeper."
