To save a life...could you take another?
You come home to find your wife missing - and the body of a woman you've never seen in her place.
A phone in her hand starts to ring. A voice says you have 24 hours to clear your name; 24 hours to save your wife.
But there's only one way to do it. You must kill someone for them. Someone you've never heard of.
A complete stranger. And the clock is ticking....
Relentless, gripping and full of twists, this is a masterclass in suspense where nothing is what it seems and no one is to be trusted.
