A gangster runs his empire from behind the walls of an asylum in this witty crime thriller: “Bruno’s novels have been total pleasure” (People).   Mobster or mental case? That’s the question at the heart of FBI agents Mike Tozzi and Cuthbert Gibbons’s latest case. Sal Immordino, incarcerated in a psychiatric institution, is actually plotting his comeback with the help of his sister (the nun) and a serial-killer-in-training. Bodies are piling up—and Gibbons and Tozzi have to throw out the rule book to keep Immordino off the throne . . . .   “The climax, set at a big Mafia funeral, is hilarious . . . This series dazzles with fast, intricate plotting, terrific characters and humor.” —Publishers Weekly
