The Thin Blue Line

Grim and Foyle frame a drug dealer by planting evidence at the scene and Goody, having found the "evidence", is to testify and is trained by Fowler to handle the pressure.

The Gasford police has to arrest an illegal immigrant. Inspector Raymond C. Fowler first makes sure his officers get an elaborate brainstorming about tolerance and non-discrimination, a particularly sensitive subject for ethnic minority Constables Frank Gladstone (Trinidadian origin) and Habib (Pakistani), so the hypothetical example is a Martian. Meanwhile shamelessly bigoted CID inspector Fowler fails to get accepted into a real masonic lodge, and pledges an absurd secret society instead.

The Gasforth PD are to be in a fly-on-the-wall documentary. Naturally, everyone wants to look good for the camera.

CID plan a raid on a rave party. Meanwhile, Habib's drug-addicted little sister comes to Gasforth.

Gasforth Football Club are to play in a qualification game for Premier League, and since this has attracted a lot of tourists and investors, Mayoress Wickham orders the police to make sure everything goes as planned.

Patricia joins an environmentalist group, the Dongers, who are protesting against a bypass. Soon the rest of the Gasforth police are called in.

The promotion board will be visiting the Gasforth police station and Grim and Fowler are the most likely candidates. When Grim tells Fowler that they usually go for family men, Fowler proposes to Dawkins in a most unromantic way, causing her to break up with him.
