Now You See Him — Stella Cameron

Two years ago Ellie Byron was the only witness to the brutal murder of a young woman. Charles Penn, a hard-eyed man with a history of violence, was convicted of the crime. Now he's escaped - and another woman is dead.

Ellie fears she may be next and turns to the only person she trusts: attorney Joe Gable. Joe would give his life to protect Ellie, but neither of them knows just how deadly an enemy they face - or how close he is.

Then the police discover that both crimes mirror events in a bestselling mystery series. And when the third book in the series is released, Joe and Ellie realize that time has run out. Because in this book the killer eliminates the only threat to his freedom. The last death is the death of the witness.
