Someone has left a severed hand in the centre of Manchester, and the only clue Detective Sergeant Jessica Daniel has to go on is CCTV footage of a woman in a long, black robe placing it carefully on the ground. With a lengthy missing persons list and frantic families wondering if the body part could belong to their absent loved ones, she has plenty to deal with - and that's before a detached finger arrives for her in the post.

Was the biggest case of his career the worst mistake he ever made? Ten years ago, DCI Jack Logan stopped the serial child-killer dubbed "Mister Whisper", earning himself a commendation, a drinking problem, and a broken marriage in the process...When another child disappears a hundred miles north in the Highlands, Jack is sent to lead the investigation and bring the boy home. But as similarities between the two cases grow, could it be that Jack caught the wrong man all those years ago?

When six-year-old Olivia Adams disappeared from her back garden, the small community of Stoneridge was thrown into turmoil. How could a child vanish in the middle of a cozy English village? Thirteen years on and Olivia is back. Her mother is convinced it's her but not everyone is sure. If this is the missing girl, then where has she been - and what happened to her on that sunny afternoon? If she's an imposter, then who would be bold enough to try to fool a child's own mother - and why?

A young woman is brutally attacked on her way home. It looks like she was the victim of a jilted—and twisted—ex-lover. But then two more women, also engaged to be married, are found dead. The press call the killer the "Surrey Stalker". And there’s a stack of similar cold case files. The pressure is on for young, ambitious DI Rob Miller. But with all the time he’s spending at the office, Rob’s also running a fine line trying to keep his fiancée, Yvette, onside as they try to plan their wedding.

Wheeling my suitcase down the familiar, hedge-lined street, I smile at the sound of children playing in the park nearby. Suddenly, there’s a screech of car brakes. I rush over to see a bent bike wheel sticking out of the ditch, and underneath, a little boy.... 

I stare at the newspaper article about a baby snatched from the back of a car 30 years ago and wonder why someone would post it through my door. Looking closer, my blood freezes. The little girl in the photo has an unusual scar - just like mine. I’ve never met anyone with one like it. Is this stolen child...me? Trembling with shock, I know I have to confront my mother. My parents got me through a horrific accident, helped me find a job I love teaching art, and even with buying my own house. But was it all built on lies? 

Paige, Richard and me. We thought we’d be friends forever. But everything changed the day we took the shortcut home from school along the old railway line. I wish we’d gone the long way. I wish we hadn’t seen our classmate, pale and still in the undergrowth. And I wish we hadn’t promised to keep one, awful detail a secret just between us.... 

Rose Denton wakes up in her car. She has no memory of how she got there. But she knows something bad happened.... There’s blood on the windscreen and bonnet - but it’s not hers, and there’s no sign of anything or anyone she might have hit. The last thing she remembers is being in a hotel on a business trip, but now she’s miles away. Back home, her daughter’s boyfriend is missing. The last thing he did was argue with Rose over money. He left no note, no text, no clue as to his whereabouts. The police have questions - and so does Rose.

When the chief suspect in the notorious "peekaboo cop killer" case blew himself up, almost taking lead investigator DCI  Duncan Bone with him, the psychologically damaged detective thought his days on the force were over. But, when another PC is abducted and murdered in the same deranged peekaboo fashion, Bone is persuaded to return to lead the new investigation.

When the body of a woman is found hanging from a tree in her front garden, rookie Detective Morgan Brookes is first on the scene. But Olivia Potter is past saving. And when her husband and daughters cannot be traced, Morgan knows there is more to this tragedy. And then she finds them. Lying huddled together in the dark basement, each of their faces covered with a small cotton cloth, their bodies cold to the touch. But as Morgan kneels beside the family, she realizes that one of the girls is still breathing.

The death of a local sex offender places the police officers at East Rise incident room under immense pressure - they must treat this case like any other murder, but they know what Albie Woodville did and can feel little sympathy. Except as the investigation progresses, it becomes clear this isn’t just a one-off killing - someone is out for revenge....

When a woman's body is discovered in a cathedral and hours later a young man is found hanging from a tree outside his home, Detective Lottie Parker is called in to lead the investigation. Both bodies have the same distinctive tattoo clumsily inscribed on their legs. It's clear the pair are connected, but how? The trail leads Lottie to St Angela's, a former children's home, with a dark connection to her own family history. Suddenly the case just got personal.

When the naked, battered body of an unidentified teenager is found dumped in an alleyway, postmortem finds evidence of a harrowing series of events. Another teenage death with the same MO pushes DI Hannah Robbins and her team on the Nottingham City division Major Crimes Unit to their limits - and across county borders.

Rookie detective Anna Travis has been assigned to her first murder case - a series of killings that has shocked even the most hardened on the force. Over the past eight years there have been six victims - all women from similar backgrounds, all killed in an identical way. Then a seventh body is found, but this one doesn't fit the pattern.

Five figures gather 'round a shallow grave. They had all taken turns to dig. An adult-sized hole would have taken longer. An innocent life had been taken, but the pact had been made. Their secrets would be buried, bound in blood. Years later a headmistress is found brutally strangled, the first in a spate of gruesome murders that shock the Black Country.
