When freelance photographer, Jacques Murphy, finds a dead body beside the River Clyde in the centre of Glasgow his first instinct should be to reach for his camera. But for Jacques this is no dream photo opportunity, it's the start of a nightmare.Two years earlier, in the south of France Jacques had found the body of his ex-girlfriend, Chantal, beside the River Garonne. The French authorities regarded Jacques as their prime suspect but after a year-long investigation, they decided they couldn't make a case against him. But the victim's family and the French press were not so easily satisfied and Jacques moved to his father's native Glasgow looking for a fresh start.Scottish police initially treat him as a witness in their case, but when they learn of Jacques' past he swiftly moves from witness to suspect. The French police and media learn of this latest murder and Jacques finds himself under scrutiny once more for Chantal's murder.Over the next few weeks Jacques is linked to three more murders, all in similar riverside settings and he increasingly becomes the focus of the police investigation. When police find photographs of the murder sites on his laptop it looks like an open and shut case. As the evidence against him mounts, and ghosts from his past come back to haunt him, Jacques has to fight not only for his freedom, but for his very survival.
