A Nest of Vipers by Andrea Camilleri

A Nest of Vipers is the twenty-first novel in Andrea Camilleri's irresistible Inspector Montalbano series.

Quite a family, you had to admit! A nest of vipers might be a better description . . .
An elderly man is found dead in the dining room of his Vigàtan beach house; his coffee spilt across the table, a gunshot wound through the back of his head. The son who discovered the body has the most to gain from his father's untimely death, and his sister is quick to point out the reasons why. But as Inspector Montalbano learns more about the victim's dishonourable life, he soon finds half of Vigàta has a motive for the murder. The inspector truly has his work cut out for him this time.
