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. The latest trainee detective to work with him is the son of a member of his former team, and together they begin to unravel the truth about what happened to Wayne Fletcher. As the investigation proceeds, it becomes clear that others are involved - some seem determined to prevent it, some seem to be taking too much interest. In the end Smith operates alone, having stepped too far outside standard procedures to ask for support. He knows that his own life might be at risk but he has not calculated on the life of his young assistant also being put in danger. He might still get his man but at what cost?

“We are living in the departure lounge,” said Ralph Greenwood, “and flights leave with monotonous regularity.” So 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. 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, while, despite his best efforts, his social life also becomes a little more complicated. To top it all, Kings Lake has been waiting weeks for the snow to fall, in a winter that seems as if it will never end… This, the second DC Smith investigation, follows on from 'An Accidental Death'.

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 unravelled, Smith must get a new team working together; Waters and Murray are still there but one of Wilson’s men is transferred to him, and the female detective constable from Longmarsh poses some unexpected problems for her new sergeant. Together they begin to investigate the links between the companies and the people that bring ashore the oil and gas, and they also find themselves caught up in the seamier side of life that exists beneath Lake’s everyday comings and goings. Jo Evison begins to delve more deeply into the story of the Andretti murders, and Smith himself has to face the fact that he might no longer be considered fit for duty.

In the peace and tranquillity 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? As Smith and his team begin to untangle the threads, one thing becomes clear – they are dealing with some of the most dangerous people that they have yet encountered.

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 neighbour 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. This is Smith’s fifth investigation but this time it’s personal.

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. Arrests are made, charges are brought and Christopher Waters asks Smith if he has ever seen the wrong man convicted in a murder case. The answer is yes, and the next question is, what can be done to prevent it happening again?

Listening Length: 13 hours, 29 minutes 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 agonising death out there. As the team from Kings Lake uncover his story, they reveal another, much older one with its origins far back in the previous century. In the tide that governs the affairs of men, it seems, love and loss, betrayal and revenge are timeless themes. Readers of Colin Dexter, P D James and Ruth Rendell have all found much to enjoy in DC Smith's previous investigations.

When fourteen-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 thirteen 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.

He said if he hadn't heard from you by high noon today, he was going to strap on his six-guns and ride back into town. So I think you should call him, Charlie. Call him before you come home. 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.

This is DC Smith’s third investigation with the Diver and Diver Associates agency. They have been asked by a member of Norfolk’s aristocracy to look into the tragic death of her younger brother, Freddie, the late Lord Thorpe of the title. The inquest verdict was of misadventure, but it isn’t long before Smith begins to suspect there has been a serious miscarriage of justice.
