Diplomat Jess Turner is the British Consul in Canberra. When a British businesswoman is brutally murdered in a Queensland resort, Jess travels to Brisbane to liaise with the police, and help the victims next of kin, her journalist sister, Susan. Queensland DI Tom Sangster is assigned the case, but the Federal Government is very interested in it too. The murder victim was negotiating a multi-billion dollar deal to supply LNG to China, and soon rumours of corruption swirl around the intelligence community. Was she taking Chinese bribes? Jess is taken aback by Susans deep suspicion of the police. When Susan snatches her sisters diary and disappears - and two more high profile murders follow in quick succession - the race is on to find Susan and the diary before the killer does. Jess and Sangster, each with their own pieces of the puzzle, must work together to solve this case.
