In a big Glasgow department store, shoplifting is an inevitable cause of loss. But when the losses skyrocket, the managing director senses that a highly organized swindle is in progress and demands action from the police. The mystery deepens when the head woman buyer disappears. Two savage murders follow in quick succession and the hunt is on - a hunt that leads full circle back to the store itself, as the cornered killer tries to fight free. Originally published in 1959.
