Brisbane 1999. It's hot. Stormy. Dangerous. The waters of the Brisbane River are rising and the rains won't stop. People's nerves are on edge. And then... A body is found. And then another. And another. A string of seemingly ritualised but gruesome murders. All the victims are men. Affluent. Guys with nice houses, wives and kids at private schools. All have had their throats cut. Tabloid headlines shout, THE VAMPIRE KILLER STRIKES AGAIN! Detective Sergeant Lara Ocean knows the look. The 'my-life-will-never-be-the-same-again look'. She's seen it telling a wife the brutal way her husband was murdered; telling a mother you need her daughter to come to the station for questioning; and staring into the eyes of a murderer wondering if you have made a mistake and the real killer remains free...
