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.

I’ve been married to my kind, loving husband Lachlan for over twenty years. He’s my everything. We have two teenage children, a beautiful home and I feel so lucky to live this perfect life.

First, the murder of the woman in the small, Scottish village where he grew up and more recently the shocking death of a woman who lived round the corner from us. The thought makes my head spin. It’s just a coincidence, surely?

It’s important to know everything that’s happening on West Street.

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.

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…

Amber was gone, leaving behind only a note: I’ve run away. Fifteen years later, Lucy is planning her dream wedding to Josh – until a body is discovered.

The perfect place to give their six-year-old son a new life. But then a woman at the school gates asks Emma if she is really married to ‘that man’. ‘Which man?’ Emma asks. The woman replies…

She told me she was the housekeeper, and who was I to question? Our stay in this perfectly renovated Victorian house on the rich side of Hastings was a favour from an old school friend while the fire damage to our own little place was being fixed. This is not my house, and they are not my rules. So I step aside, and I let her in. Am I paranoid to think that she’s watching my every move? What am I supposed to do when she rests her head on my husband’s broad shoulder, a glint in her eye that only I can see?
