She’s the shoulder you cry on when the father of your children disappears. She’s the person you turn to when he comes back, begging for forgiveness. She’s by your side when you discover his guilty secrets. She helps rock your babies to sleep when they cry. She’s your friend when you have no one else. She’s the woman upstairs, whose feet you hear treading above as you drift off at night, thankful you aren’t alone.    

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.

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.

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven. 

The phone rings. What Eva doesn’t realize is that the call will signal the end of what she knows to be true. The end of trusting her family. And the end of everything keeping her safe. The phone call is from a hospital hundreds of miles away. A woman has been admitted with a serious head injury, saying she’s Eva’s older sister. A sister Eva never knew she had. Whose name - Nancy - has never once been mentioned by her parents. It seems impossible. Could the two people who brought Eva up have lied to her for her whole life?

Kelly is taking her twin daughters to their first day of school, ushering them into the classroom, her heart breaking to think they might not need her any more, when she turns around and sees that her newborn baby is gone. As a desperate search ensues, baby Noah is quickly found - parked in front of a different classroom. But when Kelly reaches forward to comfort him, she finds something tucked beside his blanket. A locket that belonged to her sister Freya. A locket Kelly hasn’t seen since the day Freya died.

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.

Ten years ago he killed my son. Today I married him. Ten years ago my darling son Jesse was murdered and our perfect family was destroyed. My strong, handsome boy, so full of life, became a memory, a photo I carried with me everywhere. But today I’m finally close to finding happiness again. My ash-blonde hair has been curled into ringlets. Carefully placed white flowers frame my delicate features. The small, drab chapel has been prettied up with white satin, and there are tiny red hearts scattered on the small table where I will soon sign the register with my new husband. 

Faye Townsend has planned the perfect summer trip for her family. But returning to the small seaside town her husband grew up in does not go to plan - the rain pours, and the long days become stifling. And then the unthinkable happens.... Her husband, Jake, and her six-year-old son, Dylan, go for an early morning walk along the beautiful, windswept clifftops. They don’t come back.

I’m Lucy, and I have a secret I have a beautiful home that I’m desperate to escape. But that’s not my secret. I tell my friends I’ve never wanted children when I always have. But that’s not my secret. My husband is a celebrated surgeon who tries to control me. But that’s not my secret. Adele knows. Once upon a time, I knew everything about her and she knew everything about me. Best friends forever. But now our secret is beginning to surface. I can trust her more than anyone. We made a pact. And she’s never do anything to hurt me. Would she?

Everyone in the village admires Anna because she’s a wonderful mother. Juggling family life with a small sewing business, she’s the one they turn to for a warm hug after a hard day. Her kind, polite daughters are a credit to her - even Bay, her stepdaughter, whom Anna loves as much as her own two girls. But normal family life changes overnight when Anna’s middle daughter’s beauty catches the eye of a stranger in a café. As jealousy erupts between the siblings, Anna’s perfect blended family begins to unravel around her. 

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 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.

Karla watches silently as Jason hurriedly packs his belongings into a suitcase. She knows that her stillness is unnerving him as she watches his every move from the doorway of their bedroom. "I’ve fallen in love with someone else", he’d said to her, just moments earlier. The brutality of those words hit Karla hard and she struggled to breathe as she took in each word in turn. You may think you know what Karla will do next. But you’ll be wrong. Because Karla isn't who you think she is. Only she knows what's about to happen. And you will never see it coming.
