The Deep [EPUB ebook] 

Deep was back in town after a twenty-five-year exile — to inherit an empire and avenge a death. He and Bennett had made the inheritance pact when they were kids; they had known that even New York was too small for them to share and so they had tossed a coin to determine who would stay and who would build his organisation in another town. Deep had lost and gone. But now Bennett has been murdered in his own home and Deep is ready to prove he’s strong enough to take over. Deep wants Bennett’s killer, the others want Bennett’s job. And all too many of them — including the beautiful Irish — want Deep dead . . .
