A serial killer is burning people alive in the Lake District's prehistoric stone circles. He leaves no clues, and the police are helpless. When his name is found carved into the charred remains of the third victim, disgraced detective Washington Poe is brought back from suspension and into an investigation he wants no part of. He is reluctantly partnered with brilliant but socially awkward civilian analyst Tilly Bradshaw, and the mismatched pair uncover a trail that only he is meant to see. The elusive killer has a plan, and for some reason Poe is part of it.

Was the biggest case of his career the worst mistake he ever made? Ten years ago, DCI Jack Logan stopped the serial child-killer dubbed "Mister Whisper", earning himself a commendation, a drinking problem, and a broken marriage in the process...When another child disappears a hundred miles north in the Highlands, Jack is sent to lead the investigation and bring the boy home. But as similarities between the two cases grow, could it be that Jack caught the wrong man all those years ago?

A skeletal body is unearthed in a wooded area of Peterborough, Cambridgeshire. DI James Bliss, together with DC Penny Chandler, investigates the case and discovers that the young female victim had been relocated from her original burial site. A witness is convinced that a young female was struck by a vehicle back in the summer of 1990 and that police attended the scene. However, no record exists of either the accident or the reported victim. As the case develops, two retired police officers are murdered. 

A family is gunned down in the snow, but one of the children survives. Three years on, that child takes revenge, and the Snow Killer is born. But then, nothing - no further crimes are committed, and the case goes cold. 50 years later, has the urge to kill been reawakened? As murder follows murder, the detective team tasked with solving the crimes struggle with the lack of leads. It’s a race against time and the weather - each time it snows, another person dies.

A woman screams in pain. Twenty-seven times, until she dies. The sound file was sent to DCI Mark Lapslie from an anonymous email address. Why is she screaming? Why would someone record that horrifying noise? And why send it to him? He soon learns that the file was sent from the hospital where he is being treated for synaesthesia - a neurological condition that cross-wires his senses so he tastes sound - and where his new girlfriend works. 

Criminologist Martin Knight lives a gilded life and is a thorn in the side of the police. But then his wife, Liz, goes missing. There is no good explanation and no sign of Martin.... To make things worse, Liz is the ex-girlfriend of DCI Craig Gillard who is drawn into the investigation. Is it just a missing person or something worse? And what relevance do the events around the shocking Girl F case, so taken up by Knight, have to do with the present? The truth is darker than you could ever have imagined.

DCI Michael Lambert thought he’d closed his last case.... Yet when he’s passed a file detailing a particularly gruesome murder, Michael knows that this is no ordinary killer at work. The removal of the victim’s eyes and the Latin inscription carved into the chest is the chilling calling card of the ‘soul jacker’: a cold-blooded murderer who struck close to Michael once before, 25 years ago. Now the long-buried case is being reopened, and Michael is determined to use his inside knowledge to finally bring the killer to justice. 

When a body is found on a lonely cliff top path, the angelic face of a murdered teenager lies facing the rising sun. Strangled by the hands of an unknown killer, it falls to DI Tom Janssen and his fledgling team to find out how she came to be there.

Seemingly, all that could threaten this promising teenager’s life was Holly herself.

As a massive storm batters the Scottish coast, Gordon Smith’s home is falling into the North Sea. But the crumbling headland has revealed what he’s got buried in his garden: human remains. With the storm still raging, it’s too dangerous to retrieve the bodies, and waves are devouring the evidence. Which means no one knows how many people Smith’s already killed and how many more he’ll kill if he can’t be stopped. The media are baying for blood, the top brass are after a scapegoat and ex-Detective Inspector Ash Henderson is done playing nice. 

Holly Wakefield works for the NHS as a criminal psychologist specialising in serial killers. She has particular reason to be good at her job - but she keeps that to herself. When DI Bishop from the Met Police approaches Holly to investigate a recent killing, Holly is horrified by the dismembered bodies and the way they have been theatrically positioned. More shocking still is when the pathologist reveals this is not the first time she has seen these mutilations. It means a serial killer is out there, and they're going to kill again - soon. 

A victim. A mutilated body. A single word. A young woman is found dead on the streets of London. Her throat slashed, her body mutilated, and one word carved into her flesh: “DON’T.” Detective Superintendent Ray Paterson is assigned to the case. Young, handsome and from a wealthy background, he’s tipped for the top. He joins a team based out of Bermondsey, South London. It’s meant to be a stepping stone to his next promotion, but this case will threaten to bring down his career and everything he thought he knew about policing. 

One psychopath. One killer. The Stabber. Six victims, all wife beaters. Each stabbed to death through their left eye. Six victims, all wife beaters. Each stabbed to death through their left eye. The cobbled lanes and backstreets of St Andrews provide the setting for these brutal killings.

On a cold winter's morning, the body of a young boy is discovered in Epping Forest. The body is pristine and peaceful, his head resting gently on a pillow, an angel pendant clenched in his small fist. It is a murder as carefully planned as it is brutal, and there's one person DI Bishop needs back on his team to help solve such a calculated crime. Holly Wakefield, clinical psychologist for the Met Police, is better than anyone Bishop knows at getting inside the brains of psychopaths.

Detective Megan Thomas hoped that moving to Devon would mean a quiet life. Her years undercover in London left her broken and alone, unsure if she would ever recover. Slowly, she’s learning to work with a team and trust other people. But when her sister, Debbie, finds the body of local businessman Greg Porter, that peace is shattered. Porter’s wife and children don’t seem entirely grief-stricken, and his business dealings are not all they appear to be. So why are the police so determined to focus on Debbie?
