He cannot obtain a lead on a client's missing daughter and all his other cases seem boring. His friends feel he needs a vacation. He agrees and goes to Atlantic City where he becomes embroiled in a strange serial killer case in which the throats of the victims have been bitten off. Proctor is back in his element dealing with a deadly case that rings supernatural to the sleuth. Charles Grant is a very cunning writer, who leaves hints and tiny clues that provides the direction this series seems to be taken one puzzle piece at a time.
