The National Crime Agency Series

When the body of a man is discovered in woodlands outside Manchester, a ten-year missing-persons investigation can finally be filed away. But this was no ordinary death: gagged, bound and buried alive, he was the victim of a sophisticated and sadistic killer. And there is something else that has the National Crime Agency puzzled. A single character carved into a nearby tree.

A violent attacker is on the loose. His calling card: a tattoo on his victims' skin. With no witnesses and no evidence left at the crime scenes, it will take all of the National Crime Agency's resources to track him down. At the head of the investigation, codenamed Operation Juniper, Senior Investigator Joanne Stuart knows that the clock is ticking. The time between abductions is decreasing and the perpetrator grows ever more brazen. She fears it won't be long before his assaults turn deadly.

A serial killer haunts the streets of Manchester, targeting vulnerable working girls in the dead of night. His signature: a tangled lock of hair in his victims' throats. As the body count rises, pressure mounts for the Greater Manchester Police and the National Crime Agency's Behavioural Sciences Unit. For Senior Investigator Joanne Stuart, the race is on to catch the twisted killer before he strikes again. With DCI Gordon Holmes on her back and the press following her every step, Jo will stop at nothing to bring the murderer to justice.

It was the perfect crime: a murder from afar, the culprit escaping hours before drug lord Ronnie O’Neill breathed his last breathe. Now a rival gang leader’s daughter has been kidnapped and the race is on to find a silent killer and a missing schoolgirl before more blood is spilled. Senior Investigator Jo Stuart is tasked with finding the perpetrator, but when another body turns up that is seemingly unrelated to O’Neill it throws all her theories into the air, leading Jo to wonder if there’s more to the case than meets the eye.
