DS Aector McAvoy must face the dark, disturbing secrets of his past if he's to keep his family safe.

The clairvoyant is found with her tongue crudely carved out, a shard of blue crystal buried deep within her mangled ribcage.

The crime scene plunges DS Aector McAvoy back twelve years, to a case from when he was starting out. An investigation that proved a turning point in his life - but one he's tried desperately to forget.

To catch the killer, he must face his past. Face the terrible thing he did. But doing so also means facing the truth about his beloved wife Roisin, and the dark secrets she's keeping have the power to destroy them both completely.

David Mark brings Hull to dark, brutal life in this gripping novel in the critically acclaimed DS McAvoy series - a perfect pick for fans of Denise Mina, Val McDermid and Peter Robinson.
