Coworkers Ruby and Harry are in love - but they’re married to other people. They decide to tell their spouses that their marriages are over and to start a new life together. Ruby has wanted to leave her controlling husband for a while, so she tells him she’s leaving and waits at the hotel where she and Harry are to meet. But Harry never shows up. Suddenly, Ruby has lost everything.

You leave for work one morning. Another day in your normal life. Until you come home to discover that your boyfriend has gone. His belongings have disappeared. He hasn't been at work for weeks. It's as if he never existed. But that's not possible, is it? And if he has gone without a trace, why do you still feel that someone is watching you?

Just four words were printed in the card. He doesn’t love you. I’ve been dreaming about this day - marrying Adam, my childhood sweetheart, who I’ve loved for 18 years. I didn’t realize the perfect day would turn into the perfect nightmare. I was so excited to send out the wedding invitations, carefully writing everyone’s names on thick cream paper in beautiful cursive script. I had no idea I was inviting someone to destroy our marriage. 

Seven-year-old Beatrice has gone missing. Her mother Claire’s whole world has been turned upside down in just one moment, and she can’t stop shaking. She’s desperate to find her precious daughter, but nothing about the day she disappeared makes sense.

I’d heard of the Baby Caroline case, of course. When a baby is snatched from her mother’s arms, the whole country knows about it. I knew about the parents left lying by the swimming pool, the open window in the nursery. But I never dreamed it had anything to do with me. Today, my beautiful daughter turned one. We were unwrapping gifts and blowing out candles when the knock came at the door, and they took my mother away. The police say she’s not really my mother. That she stole me, 30 years ago.

When Freya first met Phil, she thought he was the man of her dreams. He bought her roses every week, booked surprise trips to sun-soaked destinations, and showed her affection like she’d never experienced before. But over time the dream had become a violent nightmare. And now Freya is packing her bags, knowing it’s time she escaped their increasingly broken marriage. But then Freya gets a visit from the police. Phil’s been in a horrific car crash and - as he comes around - it becomes clear that he remembers nothing since their blissful honeymoon two years before.

Tucking her little boy Ollie into bed one night, Sarah notices his beloved teddy bear, which she bought him when he was born, is missing and in its place is a new toy given to him by her ex-husband’s new girlfriend, Laura. When she asks Ollie about it, he begins to shift uncomfortably before whispering, "Laura told me a big secret, and she said I can never tell you." Soon, Ollie is asking to spend more time with his dad and Laura, and shrinking away from Sarah. Then, when she calls to him in the garden one day, Ollie doesn’t answer back. 

The perfect husband...After a difficult pregnancy, Esther is grateful that her forward-thinking husband, Robin, offers to put his career on hold so that she can return to the job she loves. The perfect father...Robin flourishes in his new role of stay-at-home parent, but Esther finds leaving her daughter behind to go to work more challenging than she'd thought, and soon the imbalance in their relationship brings old tensions to the surface. A perfect lie? Then one day Esther arrives home from work to find Robin and Riley are missing. 

When Becca’s first love shows up on her social media feed, she can’t help but smile fondly. Once upon a time Connor was the love of her life, and though it was over 10 years ago, he’s always held a place in her heart. Then he sends her a message. He sounds happy - still kind and funny, still living across the world in Australia. But he wants to know everything about her life now. How can Becca tell him the truth? About her workaholic husband, her stressful job, and the challenges of caring for her elderly father and her three-year-old daughter, Mia?

I wrap my arms around the tree trunk, pressing my cheek against it until the bark digs in and the missing poster is finally secured. I try not to look at the photograph on it. At the features so similar to mine. Perhaps this will be the year someone comes forward. Were crucial mistakes made by detectives from the very beginning? Could the pressure of living two lives have led my sister to run away - or even end it? Or did someone in her tight circle of friends and family have reason to want her gone? Someone out there must know something. 

You're not who you say you are. Neither is she. She thinks she knows me. She believes my marriage is falling apart at the seams, that my husband can barely look me in the eyes. She thinks I’m desperate for a baby, that my longing for a family keeps me up at night. As much as I hate to admit it, all of this is true. She thinks I listen to her advice, that I care about her opinion. That couldn’t be further from the truth. Because she has no idea who I am. She has no clue that I know everything. I know her secret. I know that she did the unforgivable. I know how many lives she ruined.

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....

Sara made one promise to herself when she was growing up in foster care: that if she was lucky enough to have a family, she’d always do whatever it took to protect them. Looking around her home with its cozy kitchen and living room, where her energetic teenage daughters and gorgeous 4-year-old son all eat, play and live together, she knows she’d do anything to keep them safe. So when Sara’s husband Matt loses his job and every shred of his confidence with it, she knows it’s up to her to bring the family back from the brink.

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.

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.
