Rumour has it that a notorious child killer is living under a new identity, in their sleepy little town of Flinstead-on-Sea. Sally McGowan was just 10 years old when she stabbed little Robbie Harris to death 48 years ago - no photos of her exist since her release as a young woman. So who is the supposedly reformed killer who now lives among them? How dangerous can one rumour become? And how far will Joanna go to protect her loved ones from harm, when she realises what it is she’s unleashed?

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. 

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.

He’s irresistibly handsome. He loves the same music as her. The same food as well. 

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....

Then Jason’s widowed boss brings back a new wife from his trip to London. Young, beautiful, reckless – nobody can take their eyes off Keisha. Including Jason.

It was supposed to be easy. Thursday would share her husband, Seth, with his other two wives, Monday and Tuesday - two women she’s never met and knows nothing about.

What do you do when you can't run and you can't hide? Lauren's daughter, Zara, witnessed a terrible crime. But speaking up comes with a price, and when Zara's identity is revealed online, it puts a target on her back. The only choice is to disappear. To keep Zara safe, Lauren will give up everything and everyone she loves, even her husband. There will be no goodbyes. Their pasts will be rewritten. New names, new home, new lives. The rules are strict for a reason. They are being hunted. One mistake - a text, an Instagram like - could bring their old lives crashing into the new.

Leah’s perfect marriage isn’t what it seems, but the biggest lie of all is that she’s learned to live with what happened all those years ago. Marie drinks a bit too much to help her forget. And Carly has never forgiven herself for not keeping them safe. 

Emily and Jake are the perfect couple. Or so everyone says. But Emily just read a letter that has shattered her perfect world. Now she only has one thing on her mind. Which one of her friends is sleeping with her husband?

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.

Since Alice’s fiancé walked out on her, she never thought she’d meet "The One". But all that changes when she meets Dominic. Handsome, charming, and kind, Alice can’t believe her luck when he proposes a few months later and moves into her West London home. Three years on, Alice’s catering business is thriving and she is married to a man she adores. So when she sees that little blue line, it should be the happiest moment of her life: they’re going to have a baby. But then the police knock on her door and Alice’s whole world is turned upside down...Dominic is dead.

When I arrive unannounced at my husband's studio in need of a shoulder to cry on after hearing that my best student, Alex, has died, I see a pair of wineglasses drying by the sink, and my deepest fear is confirmed: my husband is having an affair. Most women would fall to their knees in tears and throw him out of the house - but I just can't bring myself to do it. Instead, I go home and cook a healthy dinner for our children, walk the dog, and unload the dishwasher without complaint. I need this marriage to work to protect a terrible secret of my own....

When teenage friends Lizzie and Alice decide to head off for a walk in the countryside, they are blissfully unaware that this will be their final day together - and that only Lizzie will come back alive. Lizzie has no memory of what happened in the moments before Alice died - she only knows that it must have been a tragic accident. But as she tries to cope with her grief, she is shocked to find herself alienated from Alice’s friends and relatives. They are convinced she somehow had a part to play in her friend’s death.
