The setting is Thailand. A very important representative of the Queen is scheduled to visit Bangkok on a good-will tour. A threat has been made against his life, and somewhere amidst the golden spires awaits a deadly assassin.

He's a cynical loner, but the only man capable of tracking down the would-be killer. The tale is complex, set at a breathless pace!
