Husband, friend, colleague . . . killer?

Charlie and Emily Swift are the Instagram-perfect couple: gorgeous, successful and in love. But then Charlie is named as the prime suspect in a gruesome murder and Emily's world falls apart.

Desperate for answers, she turns to Charlie's troubled best friend, London Herald journalist, Sophie Kent. Sophie knows police have the wrong man - she trusts Charlie with her life.

Then Charlie flees.

Sophie puts her reputation on the line to clear his name. But as she's drawn deeper into Charlie and Emily's unravelling marriage, she realises that there is nothing perfect about the Swifts.

As she begins to question Charlie's innocence, something happens that blows the investigation - and their friendship - apart.

Now Sophie isn't just fighting for justice, she's fighting for her life.
