Luca Zingaretti as Salvo Montalbano, Cesare Bocci as Mimì Augello, Peppino Mazzotta as Fazio, and Angelo Russo as Catarella.
What initially seems like an isolated case of religious fanaticism quickly takes a sinister turn when a second, identical doll is found in a trash bin. Shortly after, Montalbano begins receiving anonymous letters containing riddles that challenge him to a "treasure hunt". As the riddles grow more complex and a young woman is reported missing, Montalbano realizes he is being manipulated by a disturbed maniac who intends for the "treasure" at the end of the hunt to be a corpse.
The episode balances the dark, macabre nature of the hunt with the classic charm of the TV series , including the usual banter between Salvo and his team—Mimi Augello, Fazio, and the ever-clumsy Catarella. Cast and Production
