Rory and Molly Harris drive slowly home from a dinner party. They struggle to see the road ahead - but then screech to a halt. Right in front of them a body hangs from a lightning-blasted tree at the edge of town. But it's not suicide; an elderly spinster of the parish has been murdered - and the villagers are bewildered as to who would commit such a crime, and why. The new Agatha Raisin mystery.
