Two missing women.

Rebekah Murphy is stranded on an island closed for the winter. Her family doesn't know where she is. And now a killer is on her trail. She needs to survive long enough to make it back home - but what's waiting there could be even worse.

Two pieces of the same puzzle.

Detective Travis can't find Louise Mason. The case has no leads and is getting colder by the day. Then Travis gets an anonymous tip-off -but is this a clue or part of something more sinister?

What links these apparently unrelated cases?

Who is causing young women to disappear?

And when does missing mean murder?
