Italian: L'età del dubbio) is a 2008 novel by Andrea Camilleri, translated into English in 2012 by Stephen Sartarelli.

An irritated Montalbano phones her and she calmly tells him that she won't have time to attend the funeral and that, to say it plainly, she will in fact seize this unique opportunity, his death, to extricate herself from an overlong relationship and look for pastures new.

The sea and the port of Vigata become the setting of Montalbano's new investigation, involving two vessels moored side by side at the Vigata docks: a powerful speedboat and the "Vanna", a luxury yacht whose crew has found a dinghy at sea carrying a disfigured man killed by poison.

Montalbano suspects foul play involving some of the vessels' crews and asks for the collaboration of a female officer of the Port Authorities: enter Laura, a beautiful and intelligent young woman who falls desperately in love with the Inspector, who loses his heart to her, like a passionate teenager.

Action and introspection alternate in this 14th novel, which sees Montalbano wrestling with doubts and existential thoughts whilst trying to resolve a complicated case of diamond trafficking.
