Superintendent Jack Sargent is a Western Australian Police detective, and one of the good guys. But not everybody thinks so. Someone has him in their murderous sights, and seemingly will stop at nothing to achieve their end. Sargent is dragged into a life-and-death struggle against an adversary he can't identify, and who the WA Police can't catch. His disabled son, Daniel, is caught up in the mayhem. And so is Samuel Pepys, dead since 1703, but nonetheless a key player in the drama engulfing Sargent. The killer's motives are obscure, his identity is unknown, and the advance 'clues' he provides to Sargent before each killing serve only to taunt and frustrate. People are going to die. The only unknowns are who, and how many.
