'The ending was mind-blowing...I cannot say enough good things about this book.' ⭐⭐⭐⭐⭐ Reader Review

Loving him might be the last thing they do...

Stevie Gordon is lonely, filling her time by stalking her ex-boyfriend, James Cowley. He might be married, but neither his wife nor his girlfriend knows as much about him as Stevie does.

But when James' latest mistress is brutally murdered, her body carefully posed amongst the bluebells of Thamespark, Stevie is as shocked as anyone. But with her troubled childhood taking a toll on her mind, and her heavy drinking leading to frequent blackouts, can Stevie really know she is innocent?

DI Sebastian Locke and the Thamespark squad are drawn into an urgent murder case, but as they delve deeper, they find links to a previous victim, with all the clues pointing back to James. As another innocent is targeted, Stevie becomes increasingly terrified that her own mind is betraying her.

But, is she capable of murder? And if not, who else is watching in the shadows?

A twisty, unputdownable detective novel that fans of Cara Hunter and Mark Billingham will love.
