Late on midsummer's night there is a splash in the river Thames. A body is found on an island, asphyxiated and laced with strange markings. For DCI Craig Gillard it's a baffling case. The victim's identity is elusive, clues are scarce and every witness has something to hide. Meanwhile one of Britain's deadliest serial killers is finally up for parole after a deal to reveal the location of two missing bodies. The felon has his own plans to get even with witnesses, accusers and the officer who caught him 30 years before. And who was that? A young trainee by the name of Gillard.

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. 

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.

The gruesome double-murder at an Eastvale property developer’s luxury home should be an open-and-shut case for Superintendent Alan Banks and his team of detectives. There’s a clear link to the notoriously vicious Albanian mafia, men who left the country suspiciously soon after the murder. When Banks and his team find a cache of spy-cam videos hidden in the house, the investigation pivots to another violent crime that could cast the murders in an entirely different light.

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....

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. 

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 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. 

"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 a French village, the body of a man shot through the head is disinterred by the roots of a fallen tree. A week later a famous art critic is murdered in a nearby house. The deaths occurred more than 70 years apart. Asked by a colleague to inspect the site of the former, forensics expert Enzo Macleod quickly finds himself embroiled in the investigation of the latter. Two extraordinary narratives are set in train - one historical, unfolding in the treacherous wartime years of occupied France, the other contemporary, set in the autumn of 2020 as France re-enters Covid lockdown.

When a beautiful, wealthy student is found dead in her room in Oxford's most prestigious college, Detective Inspector Bridget Hart is called to investigate.

Haunted and driven by her own personal tragedy, newly promoted DI Bridget Hart has a lot to prove as she leads her first murder case. Her investigation uncovers a tangled web of lies, lust and ambition, and brings her into conflict with powerful interests.

Niall and Eden Paternoster start their Sunday the same way they always do - with a long drive, a visit to a country house and a quick stop at the local supermarket on the way home. But this Sunday ends differently - because while Niall waits and waits in the car park for Eden to pick up supplies, Eden never returns. She’s not waiting for him at home, and none of their family or friends have heard from her. Gone without a trace, Niall is arrested on suspicion of her murder.

When a body is discovered at a popular Highland landmark, it seems like just another day on the job for DCI Jack Logan and his team. Except this body is missing a very vital component, and given its location - The Well of Seven Heads - it seems like someone is trying to send a message. But why? And to whom? 

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.
