When a dead prostitute is found floating in the river, the local police assume it's just another routine murder. But when it turns out the woman may have been a notorious East German spy, General Charles Kirk and his assistants, Michael Howard and Penny Wise, are called in from the Foreign Intelligence Office to investigate. Kirk is baffled: the evidence of numerous impeccable witnesses proves the murder could not possibly have happened, and yet there's a dead body in the morgue to show that it did. The only clue is a wooden idol in the form of a hideous, misshapen boy, found in the dead woman's room. Soon Kirk realizes that this is no case of espionage: what he is up against is an evil centuries old and long thought vanished from the earth. And when Kirk and his colleagues get close to the truth, can they unravel the mystery before they become the next victims?
