The Cat in the Hatbox

Beatrice Terwilliger, an elderly resident of the Potomac Valley Community is found dead in her home, apparently from a heart attack. But, her niece, Zelda, thins otherwise, and to make matters worse, her aunt's will is missing. At the urging of Violet and Rose Wertheim, Zelda turns to Ed Lazenby and his friend, Ernie Cardoza for help in finding out how her aunt really died, which, of course, means that Ed and Ernie are in trouble again.
