The Smell of the Night

The Smell of the Night by Andrea Camilleri is the 6th in the Inspector Montalbano mystery series.

from the back of the book:

Half the retirees in Vigata have invested their savings with Emanuele Gargano. Now the finacial wizard has disappeared, along with their money. Has Gargano flown the coop or, this being Sicily, did he run afoul of the Mafia? The ingenious new novel in Andrea Camilleri's internationally bestselling mystery series finds the earthy and urbane Inspector Montalbano investigating a labyrinthine financial scam - but at a serious disadvantage. A hostile superior has shut him out of the case, he's on the outs with his lover, Livia, and his cherished Sicily is turning so ruthless and vulgar that Montalbano wonders if any part of it is worth saving. Drenched with atmosphere and crackling with wit, The Smell of the Night is Camilleri at his most addictive

I have read the following others from this series:

• The Shape of Water (#1)
• Excursion to Tindari (#5)
• The Terra Cotta Dog (#2)

I enjoy these and pick them up when I see them, but they're not in every book store.
