A memorable birthday party is attended by the Norths. One of the guests, a lecherous, hammy actor, is stabbed to death while waiting to jump out and yell "Surprise!" Pam's the one who finds the weapon; it was hidden as a part of a model ship. Lt. Weigand realizes that any of the guests may have wanted the over-the-hill Casanova dead.

Jerry and Pamela North live in Greenwich Village in New York City. Jerry is a mystery magazine publisher who thinks he is a good amateur detective. He and his wife investigate various crimes and solve them before the police do.
