It's Camilla's first day back at work, her daughter's first day at nursery. But husband Luke is nowhere to be seen. The only trace of him is an unfinished note. Camilla tries to put it out of her mind; there must be a rational explanation.

At work, there are welcomes back, and too many distractions. Then it starts.

Breaking news: there's a hostage situation developing in London.

The police arrive: Luke is caught up in it.

But he isn't a hostage. Luke - doting father, successful writer, enthusiastic runner and eternal optimist - is the gunman. What Camilla does next is crucial. Because only she knows what the note he left behind says, and the clues it might hold...

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.

They can never assume someone isn't watching, waiting. As Lauren will learn, disappearing is easy. Staying hidden is harder...

OLIVIA: 22 years old. No history of running away. Last seen on CCTV, entering a dead-end alley. And not coming back out again. Missing for one day and counting . . . Julia is the detective heading up the case.

She knows what to expect. A desperate family, a ticking clock, and long hours away from her daughter. But Julia has no idea how close to home it's going to get. Because her family's safety depends on one thing: Julia must NOT find out what happened to Olivia - and must frame somebody else for her murder . . . What would you do?

You'd trust your sister with your life. But should you? The police say she's guilty. She insists she's innocent. She's your sister. You loved her. You trusted her. But they say she killed your child. Who do you believe?

During a family holiday in Italy, you get an urgent call from your sister. There's been an accident: she hit a man with her car and he's dead. She's overcome with terror - fearing years in a foreign jail away from her child. She asks for your help. It wasn't her fault, not really. She'd cover for you, so will you do the same for her? But when the police come calling, the lies start. And you each begin to doubt your trust in one another.

It's every parent's nightmare.

Your happy, funny, innocent son commits a terrible crime: murdering a complete stranger.

You don't know who. You don't know why. You only know your teenage boy is in custody and his future lost.

That night you fall asleep in despair. Until you wake . . .

. . . and it is yesterday.

Every morning you wake up a day earlier, another day before the murder. Another chance to stop it.

Somewhere in the past lie the answers, and you don't have a choice but to find them . . .
