It's summer in St. Denis for chief of police Bruno Courrèges, and that means a new season of cases. This time there are three weighing on his mind. First, there’s the evidence that a veteran of the French Resistance is connected to a notorious train robbery; then, the burglary of a former British spymaster's estate; and, finally, the murder of an antiques dealer whose lover is conveniently on the lam. As Bruno investigates, it becomes clear that they are connected—however, figuring out how will take every skill he possesses. Add in juggling the complex affections of two powerful women, maneuvering village politics, and managing his irrepressible puppy, Balzac, and Bruno has his hands full once again.
