I return home to our beautiful house on a chilly winter evening expecting to find my handsome husband Richard waiting for me by the fire. We’re still so in love, and he always takes care of me. He usually comes straight back from work. But tonight, our antique clock ticks on through the dark evening, with no sign of him. Then a knock at the door shatters my perfect life. A 12-year-old-girl, Alice from the village, has been found unconscious in the field behind our house. They say she was last seen getting into Richard’s car.

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 nearly threw the letter about the inheritance away with the recycling. Late for work, worrying about how I would afford new school shoes for Kate, I just assumed it was a mistake. But perhaps moving to a new home in a quiet seaside town would be the fresh start we both need. Away from the school bullies making Kate’s life a misery, and out of the clutches of my dangerous ex. 

I pinch the screen to zoom until I’m staring at the face of a ghost. A man with very short hair, staring directly at the camera with piercing brown eyes. He is as he was when I last saw him: wrinkles around the corners of the eyes and a knowing smirk. That’s the expression I see when I can’t sleep. My body tenses. It can’t be him. It’s not my ex-husband. It’s not David. I know that better than anyone because he didn’t walk out on me. He didn’t disappear two years ago and he’s not a missing person. I know that for a fact because I’m the one who killed him.

When a body is found in a locked house, Detective Sergeant Jessica Daniel is left to not only find the killer but discover how they got in and out. With little in the way of leads and a journalist who seems to know more about the case than she does, Jessica is already feeling the pressure - and that's before a second body shows up in identical circumstances to the first. How can a murderer get to victims in seemingly impossible situations and what, if anything, links the bodies?

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.

Rachel is afraid she may have done something terrible. She's sitting in a room, being asked whether she killed someone. She doesn't understand how her life has changed so completely. When she was younger, heads would turn when she walked into a room. Her children needed her; her husband adored her. But somehow the years wore that all away. She was so busy raising her children, looking after her parents.... 

Me and Will. Will and Me. A perfect match. He said he would always be there for me, but it’s been a year since he drained his coffee, walked out the front door and vanished. Did he leave me? Or did something terrible happen? I’m scared someone finally found out about what happened on the drive home that night...I lie awake at night trawling the internet for rental properties, desperate for an escape. Until I see my husband’s gorgeous face smiling back at me from a photograph on the fireplace in someone else’s home, and something inside of me snaps....

They told us he had been missing for nearly two days, that he probably drowned. They told us a lie. Megan was 10 years old when her older brother, Zac, went missing among the cliffs, caves, and beaches that surround the small seaside town of Whitecliff. A decade later, a car crash has claimed the lives of her parents. Megan and her younger sister, Chloe, return to Whitecliff one summer for the first time since their brother's disappearance.

Belle likes to think herself immune to the dizzying effects of fabulous wealth. But when her best friend Summer invites her on a glamorous girls' getaway to the Mediterranean aboard her billionaire boyfriend's yacht, the only sensible answer is yes. Belle hopes the trip will be a much-needed break from her stalled acting career and uniquely humiliating waitressing job, but once aboard the luxurious yacht The Lion's Den it becomes clear that all is not as it seems.

Clare is ready for a break. It's been a tough year and now she wants to put her feet up. Arriving at the Italian villa for their summer holiday, she decides it's high time her husband and his family did some of the work. After all, her husband owes her.... Now her brother-in-law Jamie has brought a wife, someone none of them have met before. Ella is everything Clare isn't. Glamorous. Young. Influential. But she knows a secret about Clare. Something that has the power to break the whole family apart.

No relationship is perfect. But since the birth of baby Mabel seven months ago, Amber and George have been in desperate need of a night away. Mabel is all that Amber has ever wanted, but she can’t deny that sometimes she struggles to cope. George has booked them into a luxury hotel, and Amber’s sister is babysitting. Yet just as they are ready to leave, Amber can’t suppress a feeling of worry.... 

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe. But when she came downstairs, the door was open and Abi was gone - she walked down the road, past the Lovegoods' house, and was never seen again. A year later, the Lovegoods throw a housewarming party, showing off the results of their renovation. Ava doesn’t want to go. She can’t bear to look down that end of the road, to see the place where Abi vanished, and she doesn’t want to spend time with people who don’t share her grief. 

The first time you see them, out for an evening walk on the cliffs, you’ll think they’re the perfect family. You’ll see a wife who looks so happy, strolling peacefully beside her husband in his dark winter coat, holding her daughter’s hand. But you have no idea what’s really happening in their house.... If you come a little closer, you might hear the way the man speaks to his wife. You might notice that the woman doesn’t have any close friends. That sometimes her husband doesn’t want her to leave the house.

Louise has had to watch her husband, Andrew, start a new family in the four years since he left her.

As Louise starts to dig into Caz’s past, the two women’s pretence of civility starts to slip. But in trying to undermine each other, they discover more about the man they both married. And when Andrew is murdered at a family party, both women are found standing over the body. It’s always the wife. But which one?
