It is 1906 & Will Prior is in self-imposed exile on a remote South Pacific isl&, working a small, & failing, plantation. He should never have told anyone about his previous existence as a military foot policeman in the Boer War, but a man needs friends, even if they are as stuffy &, well, German, as Hauptmann Kessler, the local government representative. So it is that Kessler approaches Will one hot afternoon, with a request for his help with a problem on a neighbouring isl&, inhabited by a reclusive, cultish group of European `cocovores`, who believe that sun worship & eating only coconuts will bring them eternal life. Unfortunately, one of their number has died in suspicious circumstances, & Kessler has been tasked with uncovering the real reason for his demise. So along with a `lady traveller`, Bessie Pullen-Burry, who is foisted on them by the archipelago`s eccentric owner, they travel to the island of Kabakon, to find out what is really going on.
