Katie Marsh

It is 5:30 am on Clio's forty-fifth birthday and her hated ex is lying dead on her doorstep. Even worse, this is no accident. Someone’s killed him...

When single mum Clio’s ex Gary turns up dead on the doorstep of her caravan – the one she’s been forced to live in ever since he stole every penny she had – there’s only one suspect. Her.

What’s more, she doesn’t remember much about the night he was killed – not just because of the forgetfulness that’s been plaguing her along with the hot flushes – but because she definitely had one too many cocktails with her two best friends Amber and Jeanie.

Clio does remember them talking about how much they all hated him though. And, in the frame for murder, she has to ask herself – if she didn’t kill Gary, who did? One of his many enemies? Or someone a little closer to home? And can she and her friends find the real killer before it’s too late?

Unputdownable mystery set on the English coast – perfect for fans of The Thursday Murder Club, Bad Sisters, and How to Kill Your Family.
