Italian La Luna di Carta) is a 2005 novel by Andrea Camilleri, translated into English in 2008 by Stephen Sartarelli.

Montalbano nostalgically recalls his boyhood and the memories of his family, remembering episodes that stayed imprinted in his imagination, like when his father pulled his leg by stating that the Moon was made of paper and he faithfully believed him.

[1] Paper Moon follows the narration of Montalbano's inner crisis and his depression about oncoming old age, which seems to be afflicting him in mind and body.

He meditates about death and the problems of growing old, with all its respective little impairments (loss of memory, sudden fears, loneliness and a propensity for crying).

The Inspector will not find it easy to solve the murder, pushed around by astute women trying to lead him to believe that "the Moon is made of paper".
