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 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.

Tormented by the recent loss of a colleague, DCI Jack Logan is on the warpath, determined to bring down all those he holds responsible for the officer's death. His quest for revenge is cut short when a woman's body turns up on the remote island of Canna, and Jack is summoned to investigate. As a storm closes in, Jack finds himself cut-off from the rest of the world, with no car, no phone signal, and only DC Neish for company,

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.

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.

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 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.

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.

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?

How far would you go to bury the truth? While searching for a missing hill walker, Glencoe Mountain Rescue Team uncovers a body - just not the one they were looking for. Still dealing with the fallout from their last case, DCI Jack Logan and his team venture south from Inverness to investigate a brutal, gangland-style execution in the wilds of the Highland countryside. As the victim's dark secrets are gradually revealed, Jack uncovers the rot lurking beneath the stunning scenery, making himself the target of a criminal more dangerous than any he has faced before.

After an elite criminal profiling unit is shut down amid a storm of scandal and mismanagement, only one person emerges unscathed. Forensic psychiatrist Doctor Alexander Gregory has a reputation for being able to step inside the darkest minds to uncover whatever secrets lie hidden there, and soon enough he finds himself drawn into the murky world of murder investigation. In the beautiful hills of County Mayo, Ireland, a killer is on the loose. Panic has a stranglehold on its rural community, and the Garda are running out of time. 

Teenager Alison Doig disappeared from Kinloch more than 30 years ago under mysterious circumstances. Her reclusive family still lives in a remote part of the Kintyre peninsula, amidst rumours of wrecking, smuggling and barbaric cruelty. Now rich American hotelier Alice Wenger has arrived in town, determined to punish those who made her suffer in the past. But someone has vowed to keep hidden sins concealed forever. Daley’s team must race against time to expose long-held secrets and shameful lies before there are any more victims.

When a girl’s body is found strangled, raped, and horrifically mutilated by a boat’s propeller, deep in the heart of the Norfolk Broads, newly arrived Detective Inspector John Tanner is asked to assist with the investigation. At first, all the evidence points to a man who had a multi-million-pound reason to kill her. But when an alibi is produced from an unexpected source, and another body appears at the base of a slipway, Tanner finds himself turning to local girl Detective Constable Jenny Evans for help. 

When Harry Falcon, a wealthy boatyard owner and decorated World War Two veteran, is found drowned in his bath, DI John Tanner and DC Jenny Evans start by questioning his two sons, each with a motive for wanting him dead. But when the elder son is found with his head smashed in under a toppled yacht, and the younger son has been talking to a local property developer, one who’d spent months trying to buy the yard from his father, the investigation soon leads them towards a dark and dangerous secret, one which nobody can quite believe.

When DI Rowan Jackman and DS Evans are told that the IT boss has disappeared, they soon suspect foul play. Orla Cracken, known as Orac, is no ordinary techie; she was once a field agent traveling abroad undercover, working for the government. Meanwhile DC Robbie Melton discovers that two people, both urban explorers, have mysteriously disappeared whilst out exploring abandoned buildings. One went missing at a disused airfield, but was it a military base, or was it civilian?
