"The Smell Of the Night" by Andrea Camilleri. Subtitled: "An Inspector Montalbano Mystery". Translated by Stephen Sartarelli. Penguin Books, 2005.
A scam artist goes missing. Did the Mafia get rid of him? Because they were jealous of his success? Or because this relatively new scam was tapping funds the Mafia would have wanted? Or, perhaps, it was time for the scam artist to reap the rewards (however ill-gotten) of his scam and despite the fact that the scam would hurt many older and poorer people. At first, Inspector Montalbano does not want to become involved with a missing person case. The particular case at hand looked like the scam artist had bailed out with the money and gone back to mainland Italy. Missing persons. Money scams. No Sicilians involved except (of course) the victims of the scam. Page 97: "Mimi asked him:' Would you please tell me why you're getting so worked up over the Gargano Case?' "
Two women! A young, cute lady who was the secretary and the older ...middle aged...good looking woman who was the office manager where the money was collected from the unsuspecting victims. Of course, murder is involved, and you'll be surprised to find out that Inspector Montalbano is an accomplished swimmer and free-diver. One body is found in the sea at the base of a cliff, but wait until you see who really got rid of the perpetuator of the scam, the initiator of the get-rich-scheme in Sicily, and where his body is found. Should Salvo Montalbano arrange the body so that the Mafia is blamed? "But he was a cop" (Page 220). All in all, this is an intriguing mystery, and, as usual, the title is not explained until you are three-fourths of the way through the book.
