And then you die - Michael Dibdin

Aurelio Zen was dead to the world. Under the next umbrella, a few desirable metres closer to the sea, Massimo Rutelli was just dead.

Inspector Zen is back, but nobody's supposed to know it. After months in hospital recovering from a bomb attack on his car, he is lying low under a false name at a beach resort on the Tuscan coast, waiting to testify in an imminent anti-Mafia trial. But when an alarming number of people are dropping dead around him, it seems just a matter of time before the Mafia manages to finish the job it bungled months before on a lonely Sicilian road. The pleasant monotony of resort life is cut short as Zen finds himself transported to a remote and strange world far from home...and wherever he goes, trouble follows.
