I Had to Do It - an absolutely gripping psychological thriller full of twists

It only takes a day for your whole life to unravel...

As Jessica Walsh sits in a café, a stranger tells her a story that feels alarmingly familiar.

She has a sister who's an addict, just like Jessica. A father growing desperate to help. There's one crucial difference, though: Jess knows her dad would never resort to violence to fix the 'problem.'

Later that morning, Jess receives several hurried voicemails from her sister: Vicky needs her. Now.

When Jess gets home, Vicky is gone, her father insisting it's all part of a plan to get her clean – but Jess can't forget that woman from the café, the strange coincidence of their meeting. It had comforted her earlier. Now it feels like a warning.

But who laid the trap?
