I've never liked my next-door neighbor, Tanya, but I'm shocked when I discover she is having an affair. She doesn't seem the type, plus her husband, Joe, is gorgeous, so why would she risk her marriage? With her secret out, I have to decide what to do next. My husband, Spencer, wants me to stay out of it. He says it's none of my business and he might be right. But news travels fast on a street as sleepy as mine and sordid secrets aren't safe in suburbia . . .

After my relationship breaks down, I agree to house-sit my brother Dexter's posh apartment whilst he’s out of the country. It will give me some much needed head space. Sitting on the balcony one sweltering summer's night in the midst of a power cut, I'm given a secret window into the lives of the residents in the opposite building, and I see more than I should. I'm drawn to a man in the Penthouse and watch him closely; when a striking woman joins him on the balcony, I can’t tear my eyes away.

When Megan loses her beloved husband, Rick, in a tragic car accident, she feels like it’s her own life that has ended. She feels too young to be a widow. Walking around the house that had been their home – so quiet without him – nothing feels the same. But at his funeral, she sees a face she doesn’t recognise. A heavily-pregnant young woman, with a sweet heart-shaped face that is somehow a little familiar. This stranger introduces herself as Emily, Rick’s estranged sister. She explains how she’s been searching for her brother for years, but she knows she’s too late now.

I take a sip of coffee as I plan my day. My surgeon husband, Cole, slept at work last night, so I had to get the kids ready on my own, again. I can’t complain, though, I’ve loved him ever since we met, long before he became a famous surgeon and the papers started calling him the pride of the hospital. Our latest family photo hangs on the kitchen wall and I remember that day so clearly. Cole screamed at me over nothing, then apologised saying he was stressed at work. My heart pounded with fear, but I plastered a smile on my face for the sake of my children.

I used to enjoy my job. I was good at it and felt fulfilled. I also used to enjoy spending time with the people I worked with. They say you spend more time with your work colleagues than you do with your family members, but that was fine by me because I made two very good friends at the office. I also allowed myself to get a little too close to my boss, but I soon realized that was a mistake. Unfortunately, it was too late by then, and as my personal and professional lives quickly blurred into one, that was when everything changed.

One thing about me: I HATE flying. It’s my worst nightmare. That’s why I book seat 2A every time I fly. Since my big win, I've been booking seats 2B and 2C as well. They’re my comfort seats, they cushion the claustrophobia, and at last I can afford them. I am now determined to live the life of luxury. I deserve it, after all. How to Live Like a Millionaire is the book I’m reading on this flight. When it lands on the floor, a handsome guy hands it back to me. I know he clocks the title, because he’s totally charming and talks to me as if I’m one of the Marbella Millionaire set.

Young married couple Heidi and Freddie just moved to Huntington Grove. All the neighbours see they are friendly and polite but why is one door in their house always locked? Across the street, Willow tries not to argue with her teenage daughter – even as her marriage is falling apart. And where does her husband really go each night, leaving the bed beside her cold?

ME: Staring down at the sweet baby in my arms, I feel panic instead of love. Because this isn’t the child I gave birth to. My husband whispers to the midwife. They all think I’m going crazy. But the tiny boy in my arms is crying again. I’m certain: he knows I’m not his mummy. And I’ll do whatever it takes to get my son back.

As if my mum breaking her hip and being rushed to hospital isn’t shocking enough for one day, now in her post-operative delirium, she’s just told me I’m not her daughter. That she has never been able to have children. The nurse reassures me that people are often confused after a trauma. But I know this woman so well and I can tell there’s a grain of truth in what she says. Which begs the questions: Who am I? Where did I come from? When I dig into the truth, I suddenly stir up a hornet’s nest of secrets, lies – and possibly a crime so unfathomable – that stretches back decades.

How well do you really know your own family? The wife: Eve is desperate for her life to be perfect. Living in a beautiful house, with gorgeous views of the countryside, is all she’s ever wanted. And she’ll do whatever it takes to hold onto her dream life. The son: Joe is a model student; he never puts a foot wrong. He knows his mother wouldn’t tolerate it. Until the night of his sixteenth birthday party, when things go horribly wrong and someone in the house is left fighting for their life. As the blue flashing lights of the police and ambulance arrive, all eyes are on the Griffiths family.

I thought my first husband died ten years ago. But now he’s back... Opening the front door, I’m stunned to see a familiar face. I never thought I’d see Freddie’s deep brown eyes and crooked smile again. But how is this possible when he died ten years ago…? It took years to move on, but finally my life is almost perfect.

On the last day of school, my friends and I gather on the beach to celebrate the long summer ahead. Sipping cans of warm cider and watching campfire embers dance into the inky sky, I don’t think I’ve ever been happier. Until a scream pierces the night. The next morning, we find shy newcomer Pippa on the beach, sandflies gathering on her lifeless body…

This is the day my life changes forever. It started so normally. The alarm went at 7am. My husband made bacon and pancakes for me and our seven-year-old daughter, the kitchen full of chatter and laughter. He gave me a quick kiss, told me he loved me, grabbed his wallet, and rushed off to work. Just an ordinary day. Until I get the call from the school. It was Tom’s turn to pick up our daughter. He must be held up for some reason. I find Tom’s phone under our bed. Now I know there’s something seriously wrong. I scroll through his messages. A text sent late last night: I KNOW EVERYTHING.
