When a Melbourne couple in witness protection are found assassinated in their bed, zoology student Josh Marshall recognises the address. He quickly realises he was an unseen witness to a bent cop divulging their location to the hitman . . . and he has the hard evidence to prove it.
Coming forward and ending up in witness protection himself is hardly an option, that is until, a one-million-dollar reward is offered on the tenth anniversary of the killings. Is there a way he and his partner, lawyer Martha Portillo, can claim the reward without ever revealing their identities?
Not without re-igniting lethal suspicions amongst the perpetrators. And not without the scrutiny of Detective Sergeant Rory James, returning to duty to face his PTSD demons. His irresolute probe winds through Bendigo, Bundoora and St Kilda to an unlikely faceoff in Margaret River.
