An act of God.. or the act of an assassin?
Sister Conchita, the young nun with a flair for detection, is immersed in another Solomon Islands investigation when an islander who claims to be a reincarnation of Noah is drowned outside his ark.
To make matters worse, Conchita suspects that the murderer might be a Japanese soldier, still prowling the jungle fifteen years after the end of World War II. Once again she enlists the aid of her friend Sergeant Ben Kella of the Solomon Islands Police Force.
Together, Ben and Sister Conchita try and track down the malevolent Killman, a professional assassin who is introducing a reign of terror to the beautiful island of Malaita that they both love so much. This time their perilous quest takes them as far as Tikopia, the tiny, wild Polynesian island of the four kings.
