The Murder Wall: It's where you look death in the face.

Months after discovering a double homicide in a sleepy village, detective Kate Daniels is still haunted by her failure to solve the crime. When a new murder gives Daniels her first case as officer in charge, she jumps at another chance to get it right.

But even more shocking than the brutal killing is the fact that Daniels recognizes the corpse. Eager to prove herself, she decides to keep her connection to the dead man a secret from her team, putting her career in jeopardy as her personal and professional lives threaten to collide.

As the killer continues to claim his victims, Daniels unearths baffling clues in her search for connections among the murders . . . and while she draws closer to finding the culprit, he is watching her.

Detective Kate Daniels must solve the death of one girl as another--who bears a striking resemblance to the victim--goes missing.

When a young girl is found dead at the base of Hadrian's Wall in Northern England, it's not long before detective Kate Daniels realizes her death was no ordinary homicide. She was thrown from a great height and was probably alive when she hit the ground.

Then a local businessman reports his daughter missing. Her description fits the dead girl exactly. Has Daniels found the identity of her victim—or is a killer playing a sickening game?

As the investigative team delves deeper into the case, half-truths are told, secrets exposed. And while Daniels makes her way through a mountain of obstacles, time is running out for one terrified girl.

Kate Daniels must make the connection between two seemingly unrelated grisly accidents...which may not be accidents at all.

Four a.m. on a wet stretch of the highway: a driver skids out of control. Quickly arriving on the scene, detective Kate Daniels and her partner, Hank Gormley, witness a horrifying display of carnage and mayhem that proves to be one of the worst traffic accidents in Northumberland’s history. But as the casualties mount, they soon realize that not all of the deaths occurred as a result of the accident …

At the same time, on the other side of town, a house goes up in flames and its two inhabitants become charred corpses. Except for the timing, there is no evidence to connect this incident with the traffic accident. But it soon becomes apparent that all is not what it seems, and that Kate and her colleagues are always one step behind a ruthless killer who will stop at nothing to get what he wants.

Skeletal remains have been discovered beneath the menacing shadows of Bamburgh Castle's fortified walls, and DCI Kate Daniels must solve her most intriguing case yet.

Far from their Newcastle base, DCI Kate Daniels and her team find themselves on the rugged Northumberland coast, working their latest baffling investigation. As a blistering weather front closes in, Kate calls on a forensic anthropologist to help identify the remains of a corpse that has been found by the ancient castle on the barren beach. But the more she delves into the case, the more questions surface.

Meanwhile, newly widowed prison psychologist Emily McCann is lured into the twisted world of convicted sex offender Walter Fearon. As his sinister mind games become increasingly disturbing, is it possible that Kate's case has something to do with his murderous past? With Fearon's release fast approaching, Emily fears what he might have in store for her.

As the body count rises, Kate must scramble to outwit a clever, diabolical killer whose fatal games have only just begun.

They know he's coming.

Two brothers from the same criminal family die within hours of each other, five miles apart—one on the edge of a Newcastle industrial estate, the other in the busy emergency room of a local hospital. Both victims have suffered horrific injuries.

Who wanted them dead? And will they kill again? Investigating these brutal and bloody killings leads detective Kate Daniels to break some rules, putting her career as well as her life on the line.

As the body count rises in the worst torture case Northumbria police have ever seen, the focus of the investigation widens to Glasgow and beyond, ending in a shocking confrontation with a dangerous offender hell-bent on revenge.

At dawn on a lonely stretch of road, a body is found hanging from an ancient gallows the morning after a country show. Hours earlier, DCI Kate Daniels had seen the victim alive. With her leave period imminent, she's forced to step aside when DCI James Atkins is called in to investigate. There's bad blood between them.

When Kate discovers that Atkins' daughter was an eyewitness to a fight involving the victim, the two detectives lock horns and he's bumped off the case. It's the trigger for a vicious attack on Kate, exposing a secret she's kept hidden for years and unearthing an even darker one.

Shaken but undeterred, Kate sets out to solve a case that has shocked a close-knit village community. As suspects emerge, she uncovers a curious historical connection with a hangman, a culture of systematic bullying, a web of deceit and a deep-seated psychosis, any one of which could be motive for murder.
