Jack of Hearts is a six-part British television crime drama series, written by Sian Orrells and directed by Timothy Lay, that first broadcast on BBC One on 4 August 1999.

[1] Set and filmed in Cardiff, the series follows the life of a tough-talking probation officer, Jack Denby (Keith Allen), who finds that life and crime in the Welsh capital is much different to the workings of inner-city London, when he is forced to move away to join his girlfriend, Suzanne (Anna Mountford), a university lecturer.

The series was broadcast on Wednesdays at 21:30, and was also repeated on Thursdays and Saturdays on BBC Choice.

[2] The series was also accompanied by a theme written especially for the series, performed by Bonnie Tyler.

Mark Lawson of The Guardian gave the series a mixed review, writing; "Keith Allen's new series Jack of Hearts, about a hard-bitten parole officer, is a textbook lesson in formulaic drama.
