The new Kings Lake Central murder squad is about to spend its first morning on team-building exercises and reviewing cold cases when the call comes in that the body of one of the city's rough sleepers has been found in a shop doorway. It happens, someone says, he isn't the first to die on the streets and he won't be the last, but the story the new team begins to uncover is far from routine.  

As the first anniversary of the formation of the Kings Lake murder squad approaches, there is a problem—they've run out of murders. As a result, they are given the task of reviewing unsolved cold cases. One of these comes back to life in unexpected ways as the team try to discover the identity of the young woman whose body was found in the Norfolk countryside two decades ago. And even if they can give her a name, how can they possibly find her killer after so many years?

Detective Sergeant Chris Waters got the call at 05.29 that July morning. This is it, said DCI Reeve, you'll be first there, it's all yours, you're the crime scene manager. Suddenly, after months of waiting and wondering, Waters finds himself in at the deep end, and alone at the scene of a puzzling murder. As the investigation proceeds, the detectives at Kings Lake Central find themselves visiting familiar places and talking to some familiar faces, while old enmities reappear in the incident room. Before this is over, Chris Waters will need to make a career-changing decision.

Charlie Hills, former desk sergeant at Kings Lake Central, is in trouble. He hasn't told Smith, his old friend and sparring partner, but someone has, and now the two former policemen are about to embark on a difficult and potentially dangerous search for the truth. For one of them, it could be life-changing.

When 14-year-old Zoe Johnson doesn't come home on a Monday night in early December, the alarm bells in Kings Lake Central police station do not ring straight away - after all, she's from the Dockmills, one of the toughest estates in the town. But for Detective Sergeant DC Smith, due to retire in just three weeks' time, there are some strange echoes of the case that has haunted him for the past 13 years. Maybe it's simply his over-developed sense of irony, or maybe, in his final days as a police officer, Smith must look once more into the eyes of a serial killer.

Mark Randall lay dead in a field near Lowacre long before Smith had done what he had to do in Belfast. By the time he went back to work, the investigation was well underway. "It's not my case," he says more than once, and he really doesn't need it to be; he has enough to think about as it is. But going around the Norfolk countryside dotting the i's and crossing the t's, speaking to the local farmers and the Brothers of St. Francis from Abbeyfields, Smith begins to suspect that the investigation might be heading in entirely the wrong direction.

When a worker goes missing from a North Sea gas platform, there seem to be just two possible explanations - it was a tragic accident or a suicide. It does not take Smith and his detectives long, however, to discover that James Bell led a double life back onshore in Kings Lake, a life complicated enough to make him at least one dangerous enemy. Before the case can be unraveled, Smith must get a new team working together.

In the peace and tranquility of the woods at Pinehills on a Saturday afternoon, a mobile phone begins to ring. The phone belongs to DC Smith, and it isn't unusual that the call is from Kings Lake Central police station; what is unusual is the fact that he seems to be the subject of an investigation rather than taking part in one. What can the links be between a prisoner's violent death in another county, the disappearance of two teenagers, and the highest profile case in Kings Lake for many years?

Two weeks of rest and recuperation - that's what the doctor ordered. Detective Sergeant DC Smith could listen to some music, make some of his own, and maybe even catch up on his reading; he is almost looking forward to it. And then there is a knock on the door. It's only his next-door neighbor, but it is the beginning of a sequence of events that will bring him face to face with some of the darkest episodes and the most dangerous people from his own past.

When another resident of the Rosemary House care home is found dead in her chair one Saturday evening in December, no one is very surprised - not until the results of a routine post-mortem reveal something extraordinary. Sergeant DC Smith and his team have to tread carefully as they investigate what took place, and Smith himself has to confront some difficult memories. Others, meanwhile, seem intent on getting him to leave the force altogether.

"So I thought I might take up paragliding. You know, buy one on eBay and just jump off the cliff one morning." Emily Willows is middle-aged, widowed, wealthy, and bored. When she makes those flippant remarks to her son over coffee one Friday, she has no inkling that within a few hours she will be facing the most terrifying situation of her life.

The story opens with the apparently accidental drowning of a sixth form student in the Norfolk countryside. As a matter of routine, or so it seems, the case passes across the desk of Detective Sergeant Smith, recently returned to work after an internal investigation into another case that has led to tensions between officers at Kings Lake police headquarters. As an ex-DCI, Smith could have retired by now, and it is clear that some of his superiors wish that he would do so.

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.

Promising architect Peter Young is shot dead at his desk. DCI Craig Gillard is on the scene, looking at what appears to be a brutal and highly professional hit: two bullets, fired with ice-cold calm. Gillard knows that the most crucial question in solving the crime is one word: why? Two weeks later, on the Lincolnshire coast, another body is found on a windswept beach. In this case there is no identity for the young man, just a curious brand burned into his neck....

One moonlit night, the bodies of two young people are discovered lying entwined on a blanket in the woods. The young man is clutching a red rose. It appears to be a lovers' suicide pact.... Until Detective Nikki Galena and DS Joseph Easter look more closely. Romeo and Juliet, as they decide to call them, were murdered somewhere else and brought to the woods. But why? Then another young couple are found dead, again beautifully posed as lovers.
