A small bushfire, but nasty enough for ice cooks to abandon their lab. Fatal, too. But when the bodies in the burnt-out Mercedes prove to be a pair of Sydney hitmen, D.I. Hal Challis's inquiries into a local ice epidemic take a darker turn. Meanwhile, Ellen Destry, head of the new sex crimes unit, finds herself not only juggling the personalities of her team but hunting a serial rapist who leaves no evidence behind.
