A hijacked delivery vehicle draws St-Cyr and Kohler into the killing fields of World War I. A bank-owned cargo van is parked near the crumbling monastery, its contents ransacked, its passengers murdered. The killers took small bills but left behind a bounty in smuggled champagne, cheese, and coffee. Even more confounding is the expensive pair of high heels left behind. Were the thieves from the Resistance, or from the underworld? Who is the mysterious woman who was wearing those shoes? St-Cyr and Kohler have a feeling that the answers are hiding in the cold French rain.
