Pauline Quirke stars as the eponymous title character, an unorthodox detective whose hands on yet down-to-earth approach is not always appreciated by her superiors.

[1] Created by Stephen Bill, a total of twelve episodes were broadcast across two series.

The first series features a running story arc involving Maisie's wayward brother Kelvin (Paul Reynolds), and had a much lighter feel than the second, which featured grittier storylines including drug dealing, armed robbery, arson and murder.

Throughout the series, Maisie is portrayed as a strong and dedicated detective, often stepping on toes and bending the rules to get results, and even becoming personally involved with the victims of each case.

She often clashes with her superior officer, Jack Freeman (Ian McElhinney), who also appears to hold a romantic torch for her, while George Kyprianou (Steve John Shepherd), a junior constable on her team, often proves to be her best ally in the field.
