Duffy (Electronic book text)

In the grimy underbelly of London, private detective Duffy takes on an extortion case and finds himself pitted against one of the city's most dangerous crime lords
Rosie McKechnie was alone when the two men entered her home, tied her to a chair, and cut her with a switchblade. It was a message for her husband, Brian. To outside appearances, Brian McKechnie is just a businessman. But to Big Eddy Martoff, London's underworld kingpin, McKechnie is a big fat mark. With a history of crooked business deals and extramarital affairs, McKechnie is the perfect target. To beat back the blackmail, McKechnie needs someone who understands lowlifes like Martoff--and Nick Duffy knows lowlifes.
Duffy was a copper until four years ago, when malicious rumors about his sex life ripped through the force. Now he is in private security, and McKechnie's case is one he cannot refuse. Duffy, no stranger to his city's seedier offerings, dives into a world of prostitutes, hoods, and porn moguls. Can he find a way to put the pinch on Big Eddy before Soho swallows him whole?
