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.  

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.

Change is afoot at Kings Lake Central police station. A most unexpected new detective inspector takes up his post this Monday morning, and the oldest detective in the place takes a momentous decision. Around them, other officers are considering their own situations, and even the building itself seems to be facing an uncertain future. But life and death go on, nevertheless, and by lunchtime someone will make a grim discovery on the Norfolk saltmarshes. A stranger seems to have suffered a slow and agonizing death out there.

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.

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.

Grace Repton, a beautiful older woman, walks into the police station to tell Detective Matt Ballard she has information that could stop a murder. Her fiance, the infamous serial killer Jeremy Reader, has told her that he has a disciple who is going to kill using Reader's horrific methods. Reader murdered five women and was finally brought to justice by Detective Ballard. Reader is safely imprisoned in a high security prison, and claiming to be a reformed man who wants to help the police.   

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?

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.

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.

When a local man, a veteran of the war in Afghanistan, goes missing, his parents have good reason to be concerned. Emily Willows is a friend of the family and says that she knows just the person to find him - and, as Summer Lane soon points out, the fact that this also fits in with Emily's plan to set up her very own detective agency is surely just a fortuitous coincidence.
