He has always been the hunter. He is about to become the prey. For years, DCI Robert Kett has tracked down the country’s most dangerous kidnappers and serial killers, earning a reputation as the best man to call to catch the worst men. The tables are about to turn. When somebody starts brutally murdering the criminals that Kett has put behind bars—and the ones that he wasn’t able to catch—it seems as if there is a vigilante on the loose. Tasked with keeping one of these criminals alive, Kett starts to understand that something far more dangerous is going on. Because this killer isn’t just coming after the bad guys. He’s coming after Kett, too. The fifth instalment in the internationally bestselling DCI Robert Kett series takes the excitement and terror to a whole new level.

In between these two books he has published thirteen novels for children and teenagers under his full name, Alexander Gordon Smith—including the number one bestselling series Escape From Furnace, which is loved by millions of readers worldwide and which is soon to become a motion picture. He lives in Norwich with his wife and three young daughters.
