Wilful Behaviour - Donna Leon

... in which Commisario Guido Brunetti investigates the murder of a surprisingly wealthy and unwordly young student and an elderly Austrian woman, whose apartment turns out to house an astounding art collection. Not that unusual in Venice but the origins of this collection turn out to have close connections with jews fleeing Italy during World War II.
