A large country mansion. A locked room. A gruesome murder. Russian oligarch Alexander Volkov has invited 1,000 guests to a party at his palatial Surrey residence, Westgrave Hall. But while giving a private tour of the library, a gunman kills Volkov, wounding his ex-wife and slaying her new beau. Nothing makes sense to DCI Craig Gillard. In the blood-spattered crime scene there are no forensic traces of anyone else involved, CCTV shows no one entered or left the library, and everyone seems to have an alibi.

DCI Craig Gillard will be pushed to his limits. But will he break? It seems like a routine disappearance, a case of musician’s stage fright. As a senior detective, Craig Gillard isn’t sure why he’s even involved. Until it turns out the woman’s father is the German minister of justice, and the British home secretary is on the case, too. But nothing about the case is simple. How does a woman on a train simply vanish? What do you do when a trail runs cold and the pressure is on? Before long the perpetrator has another target: DCI Gillard himself.

A young detective is out for a jog on a snowy winter morning. Then she sees something terrible: a murder in the park, sudden and inexplicable. A woman has been killed by a passing hooded cyclist. It’s just DCI Craig Gillard’s luck that he’s on duty. The body is that of Tanvi Roy, one of the richest women in Britain and matriarch of a food empire. With a tangled web of family and business contacts and jealousies, Gillard’s job just got even more complex. As he delves deeper into the Roy family, it’s clear that everything is not as it seems.

A body is found on a quiet lane in Exmoor, victim of a hit and run. He has no ID, no wallet, no phone, and - after being dragged along the road - no recognisable face. Meanwhile, fresh from his last case, DCI Craig Gillard is unexpectedly called away to Devon on family business. Gillard is soon embroiled when the car in question is traced to his aunt. As he delves deeper, a dark mystery reveals itself, haunted by family secrets, with repercussions Gillard could never have imagined. The past has never been deadlier.

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. 

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.

As the mists roll over the fens and enigmatic lights twinkle in the distance, only the locals know their way along the hidden paths through the mysterious watery terrain of one of England's most beautiful and sometimes dangerous places. Detective Matt Ballard may have retired but there's still plenty going on in the fens to keep him busy. Someone trashes an old lady's garden and daubs her isolated cottage with hateful graffiti. Emilia Swain seems to be totally harmless, so why is she being targeted?

"And see if there's any news about the missing girl." Life, as Smith used to say, is just one thing after another - as one investigation ends, a new one begins. But for reasons unknown to the rest of her team, DCI Cara Freeman will be haunted by the next case for the Kings Lake Central murder squad. They find themselves delving into the seamy side of life in the town, and one of their number will have departed before this new investigation is over. Perhaps Detective Sergeant Chris Waters should have seen it coming, but he has a lot more than work on his mind these days.

In North Devon, where the rivers Taw and Torridge converge and run into the sea, Detective Matthew Venn stands outside the church as his father's funeral takes place. The day Matthew turned his back on the strict evangelical community in which he grew up, he lost his family, too. Now he's back, not just to mourn his father at a distance, but to take charge of his first major case in the Two Rivers region; a complex place not quite as idyllic as tourists suppose.

Halloween, Whitby. DCI Jim Oldroyd’s daughter Louise is in town with friends for a goth festival. But their visit to an escape room ends in bloody murder when one of the group stabs his girlfriend and flees the scene. It’s a crime with three witnesses - but Louise refuses to take what she saw at face value. Oldroyd and DS Carter are called in to solve the case, assisted from the sidelines by Louise. But the closer they investigate, the more complex the web of deceit appears. This is no straightforward crime of passion. 

A body is discovered deep in a cave beneath the Yorkshire Dales. Leading the investigation into the mysterious death are experienced DCI Jim Oldroyd and his partner DS Carter, a newcomer from London. The deceased is Dave Atkins, well known throughout the village but not well liked. While there is no shortage of suspects, the details of the crime leave Oldroyd and Carter stumped. 

After a violent home invasion in the remote wilds of Glen Coe leaves a family of four dead, DCI Jack Logan and his team are brought in to lead the manhunt. But, when one of the victims is revealed to be one half of legendary 1980s Glasgow-based comedy double act, Neeps & Tatties, Logan is forced to leave the Highlands and head back to his old stomping ground.

As a massive storm batters the Scottish coast, Gordon Smith’s home is falling into the sea. The trouble is: that’s where he’s been hiding the bodies. It’s too dangerous to go near the place, so there’s no way of knowing how many people he’s murdered. Or how many more he’ll kill before he’s caught. As more horrors are discovered, ex-detective Ash Henderson is done playing nice. He’s got a killer to catch, and God help anyone who gets in his way. 

When Detective Kim Stone is called to a local business, what she sees leaves her speechless. The photo on the driving license bears little resemblance to the man laid out before her, and she knows she’s up against the most twisted killer she has ever encountered. But as she breaks the devastating news to the victim’s wife, Diane Phipps, Kim can’t help feeling that something isn’t quite right about the woman’s reaction.
