DI Jon Spicer's investigation into the vicious slaying of a Russian asylum-seeker grinds to a halt when the man's identity turns out to be false. The only truth to his story was the fact he was found drifting off the British coast in a boat. Before his true identity can be discovered, more asylum-seekers start to die — each murdered in the same horrific way. By the time Spicer realises what links the men, he knows there's a trained assassin at large who's desperate to guard a secret of enormous magnitude. And when he ignores MI5's warnings to back-off, Jon also realises, too late that he's now the target of a man whose sole purpose is to kill. And all the while, a series of heartbreaking and enigmatic messages are being found after drifting in from sea — slowly revealing the horrific plight of a group of refugees trapped on a raft. Powerful, compelling and poignant, this is the most unmissable outing to date for DI Jon Spicer.
