Much of the action on this installment in the enjoyable Aurelio Zen series is set in and around Catania in Sicily, a place that our world-weary detective had always hoped to avoid. 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.  (ITL624, $15.00)
