Probably since book three, these books are not about solving mysteries, but enjoying Salvo Montalbano's look on life. He's just as cynical as Michael Dibdin's Zen or Donna Leon's Brunetti, but he has a totally different way of looking at life in Italy (well actually Sicily, which isn't truly Italian). While Zen is always looking at the dark side, and Brunetti is more philosophical in his Venetian bastion, Montalbano lives life openly an without apology.
But at 56 the Inspector is beginning to feel that the sands are running out in the hourglass (terrible cliche, but true) and he wants to have more 'substance' to his life. He may complain about Mimi constantly being away from work because of his 'little one' but in ways he is jealous of him. He knows he doesn't want to be alone at the end of his life, but he can't come to a conclusion of how to hold onto Livia without changing his lifestyle.
In the side story of a faked kidnapping, we see Salvo judging the man who ran off with his mistress for a vacation, while his wife was up in arms that the Police were doing nothing to find him. In the main story we have four Russian girls (all with sphinx moth tattoos on the left shoulder blade), who in one way or another are mixed up in something illicit due to being in love or being loved.
Montalbano, who is the only brain in the whole book, enjoys baiting his superiors, belittling his co-workers and sating his appetite as much as any glutton. Every one else in the book is there to be used by Salvo, to either perpetuate the story or give him some one to mock. But it seems that this is all becoming stale and Salvo wants more permanence in his life. One wonders if this has anything to do with the ninety year old author!
I'm looking forward to the translations of the next three books, and hopefully at some point Camilleri will retire our Inspector, so that the series will have a 'real' ending and not just an end.
