Dibdin's stylish, dark detective is hiding out at a beach resort in Tuscany in this installment of the Aurelio Zen series. Naturally, he jumps into the action to find out who is trying to kill him. It's hard to say what we like best about Michael Dibdin's Aurelio Zen series: his knowing police detective, the thoroughly enjoyable Italian settings, fast-paced plot or wry commentary on contemporary society and politics.  (ITL619, $14.00)
