Sunday Times bestselling author Tim Weaver is back with his first standalone mystery.

You don't know your darkest secret.

But someone else does . . .

___________

Rebekah Murphy knows too much. . .

She knows she's alone on an abandoned island with a killer on her trail.
She knows that to get home to her children, she must survive long enough to understand why this is happening.
She knows someone tried to kill her for a secret.
What she doesn't know is what that secret is . . .

Detective Frank Travis doesn't know enough . . .

He doesn't know where to find Louise Mason. He doesn't know how and why she vanished into thin air three months ago. He doesn't know the identity of the man last seen talking to her. Not yet.
But what he does know it that he's a week away from retirement -- and if he doesn't find out where Louise went, no one will.

What neither Rebekah nor Detective Travis realise is that each holds a missing piece from the same puzzle -- and it will cost them everything they love to finally solve it . . .
