Mystery woman, Morrigan Doyle, is in prison.

Finn Doyle, her son, has ties to the Irish mob in New York. He became acquainted with Harry Starke when Harry was investigating his mother's billion-dollar Ponzi scheme. But Finn has an agenda of his own and wants to hire Harry to "find a friend," Matteo Rossi.

Rossi, a low-level thug, a soldier in the Irish mob, is missing and Finn is worried, thinking someone has "offed him," and he wants to know who.

Initially, Harry turns Finn down. But, as they say, curiosity kills the cat, and Harry, ever the curious cat, does a little digging and finds that Matteo's mother and girlfriend are also looking for him.

Finn, however, is nothing if not persistent and, taking into account the new information, Harry reluctantly agrees to take the case, for a fee, of course.

Thus Harry and his team embark on an investigation that takes him back to New York, following Matteo, a trail of bodies, and a litany of misinformation until ... Well, as always, there's a twist in the tale; more than one, in fact.
