Murder lurks in the wings of the sprawling Fifth Avenue penthouse of multimillionaire Otis Jarrell, who has just retained the incomparable Nero Wolfe on a case of the utmost confidentiality. But even the master detective cannot prevent tragedy when it inevitably arrives wielding Jarrell’s missing revolver.

Soon a second victim meets his maker, and Wolfe must piece together the truth behind Jarrell’s scandalously ill-behaved family. And for one member of that charmed circle—a two-time killer sleeping the fitful sleep of the guilty—it could prove a deadly awakening.
