A last-minute replacement on a role-playing weekend. One fatal accident after another. Can Macleod overcome the snowstorm from hell to stop a killer before the guest list becomes obsolete? Detectives Macleod and McGrath join a bizarre cast of characters at a remote country estate on the Isle of Harris where fantasy and horror are the order of the day. But when regular accidents happen, Macleod sees a killer at work and needs to uncover what links the dead. Hampered by a snowstorm that has closed off the outside world, he must rely on Hope McGrath before they become one of the victims. It's all a game..., but for whom?
