The Treasure Hunt

The Treasure Hunt is the sixteenth gripping novel in Andrea Camilleri's darkly humorous Inspector Montalbano series. When a crazed elderly man and his sister begin firing bullets from their balcony down onto the Vigàta street below, Inspector Montalbano finds himself a reluctant television hero. A few days later, when a letter arrives containing a mysterious riddle, the Inspector becomes drawn into a perplexing treasure hunt set by an anonymous challenger.
As the hunt intensifies, Montalbano is relieved to be offered the assistance of Arturo Pennisi, a young man eager to witness the detective's investigative skills first hand. Fending off meddling commissioners and his irate girlfriend, Livia, the inspector will follow the treasure hunt's clues and travel from Vigàta's teeming streets to its deserted outskirts: where an abandoned house overlooks a seemingly bottomless lake.
But when a horrifying crime is committed, the game must surely be laid aside. And it isn't long before Montalbano himself will be in terrible danger .
