Cos fan tutti - Michael Dibdin

In this, the fifth book in the acclaimed Aurelio Zen series, Zen finds himself in Naples, in disgrace - and having the time of his life. Like the rest of Italy, Naples is concerned about its image and trying to clean up its act. Unfortunately it seems that someone is taking this rather too literally. Corrupt politicians, shady businessmen and eminent mafiosi are disappearing off the streets at an alarming rate. This is all very tedious for Zen, whose commitment to his work is at an all-time low. He would far rather amuse himself by sorting out the romantic entanglements of his landlady's nubile daughters and putting the fidelity of their unsuitable lovers to the test. But in the end he discovers that even in the 'New Italy' of the 1990s, some things, above all love and deception, never change.
