​​​​​​​KJ Cornwall is the pen name of bestselling true crime and multi-genre author Stephen Bentley, a former British detective and barrister. It is the pen name associated with the Jessie Harper Paranormal Cozy Mystery series set in 1930s Liverpool, a city the author knows well.

They are light-hearted tales with oodles of British humour partly supplied by Khan, the magical, talking cat.

Why KJ Cornwall? The memories of Kathleen, the author's mother and Jack. her twin brother, are cherished by the author in the choice of this pen name.
