But even the master detective can't stop a killing, especially if it's an inside job -- right under the roof of his client, millionaire Otis Jarrell.What's more, it's Jarrell's own missing revolver that the killer uses. Wolfe must find the truth behind the scandals in Jarrell's ill-behaved family. One of its members sleeps the fitful sleep of the guilty, and Wolfe's getting dead-tired of murder.
