When Claudia, a young American, turns up dead in the courtyard of an ancient castle in Bruno's jurisdiction, her death is assumed to be an accident related to opioid use. But things may not be so simple, and Bruno is led to Monsieur de Bourdeille, the scholar with whom the girl had been studying, and then through that man's past. He is a renowned art historian who became extraordinarily wealthy through the sale of paintings that may have been falsely attributed-- or so Claudia suggested shortly before her death.
