A woman falls to her death from a London bank's twenty-fifth-floor roof terrace.

You're arrested for her murder.

You tell the police that you had only met the victim the previous night at your office party. She was threatening to jump down from the roof, but you had talked her down.

You've got nothing to do with this tragedy. You're clearly being framed.

So why do the police keep picking holes in your story? Even your lawyer doesn't seem to believe you.

It soon becomes obvious that you're keeping secrets.

But who are you trying to protect? And why?

Obsession. Intrigue. Revenge.

Get ready for one of the most twisty-turny novels you will read this year.
