Nevertheless, the major is found dead, and the doubter unconscious from wounds which could not have been self-inflicted, and there is nobody else in the room. Could the serial killer be an evil genie? Or is it possible that two murderers, each with the apparent ability to vanish at will, inhabit the same small village?…
