The headmaster of a school is found dead in a swimming pool; a former pupil is the prime suspect…

When Laura Wellbourne phones Professor Perry Webster, he doesn’t recall his former student by name. That’s because she was always known as Raven. Since, she’s changed her identity and cut off her shock of black hair.

Raven has been accused by the police of the murder of her former headmaster in a private school in York. Details of her time as a pupil at the academy provide a strong motive for the police. But believing her story, Webster reluctantly agrees to help clear her name, and goes undercover into the school to investigate.

Having in the past discovered who killed his girlfriend, and helped a colleague accused of another murder, Webster is no stranger to the role of private investigator. But the secrecy and deceit at the heart of the school will prove difficult to untangle. And the police won’t like him interfering.

Can he find the real murderer among the list of likely suspects? Or will his presence there lead the murderer to strike again to cover their tracks? In danger, Perry Webster must step up to the plate to tackle his hardest case yet.
