Michael McCready is a private investigator, working on the streets of north London. Separated from his wife and estranged from his daughter, his life is still far from empty. The colourful town of Kilburn has taken him to its heart as their local sheriff. His life is disrupted, however, with the arrival from Ireland of the lovely Bernadette, who hires McCready to track down her brother, Gerry. During this, he attempts reconciliation with his daughter Clare. When McCready gets her out of a little hot water, Clare solves his case - and establishes Clare as a junior investigator in the duo that is McCready and Daughter.

Michael and Clare investigate the murder of a chef working at a local Italian restaurant, and uncover a complex web of secret relationships.

McCready's attempts to find romance through a dating agency go wrong when he is arrested for the murder of his date Chrissie.

Michael's past comes back to haunt him when the disappearance of a con man and the discovery of a young girl's body bears all the hallmarks to an unsolved murder he worked on twelve years ago.

The death of a woman who had campaigned against building development arouses the suspicions of Michael and Clare. Michael offers to help a young woman whose local neighbourhood has become infested with gangs and violence, but finds himself up against the woman's volatile sister.
