The Allies have defeated Germany in Europe, but Japan refuses to surrender the East. In Singapore, amid rumours the Japanese occupiers are preparing to wipe out the population of the island rather than surrender, a young aide is found murdered beneath the termite mushroom tree in Hideki Tagawa's garden and his plans for a massive poison gas bomb are missing. To prevent any more destruction it falls to Su Lin to track down the real killer with the help of Hideki Tagawa's old nemesis, the charismatic shinto priest Yoshio Yoshimo.
