Bomb Squad Commander Lieutenant Joseph Capobianco fields an unusual request from a friend of the mayor's: Do a bomb sweep at the famed Julius School of Music and at the luxurious apartment of their visiting star tenor, Claudio Spotto. At first the team that Joe sends finds nothing in the way of bombs. But other signs of trouble mount rapidly. Someone doesn't want Spotto to remain in New York — and that someone is threatening violence via bomb. The commander soon realizes that this case has echoes of the Bomb Squad's origins in extortion from the Black Hand, evoking threats made nearly a hundred years before against the great tenor Enrico Caruso. What does this new Black Hander know about these parallels? Is this a personal challenge to Joe's early tenure as Bomb Squad commander? And, as the Black Hand grows bolder, can Joe's team stop the extortionist before someone dies in the escalating violence? You'll be holding your breath until the rousing finale!
