For Inspector Hunkeler the New Year begins with a most unwelcome phone call. He is summoned back to Basel from his holiday to unravel a gruesome killing in a gardening allotment on the city's outskirts. An old man known as Anton Fluckiger has been shot in the head and found hanging from a butcher's hook from the roof of his garden shed - like butchers hang the carcasses of dead animals.
Hunkeler must deal not only with the quarrelsome tenants of the allotment but with the challenges of investigating a murder that has taken place outside his jurisdiction, across the French border in Alsace. The clues lead to the Emmental in Berne, and then events from the last weeks of the Second World War in Alsace come to light, the wounds of which have never healed in the region.
