The Thin Blue Line

Raymond surprises Patricia by celebrating the Queen's birthday on their 10-year anniversary. Meanwhile, Grim is attempting to police shadowy alleyways of the Internet.

Grim is onto the case of his career which might be related to 'terrorism'. And Fowler is being plagued by a hoaxer who claims recently to have had morning coffee with Lord Lucan.

Grim wants to use Habib as a honey trap and ensnare Terry the Tank, while Fowler needs to find someone to replace Habib on his team to win the pub quiz final.

Complications ensue at the Rag Week, and Gasforth police have to deal with all sorts of pranks and bank robberies.

Fowler's teenage son is going to stay with him and Patricia for a few days. And Grim becomes a confidant to the Scotland Yard and is organizing anti-crime initiatives.

Fowler is planning a camping trip for young offenders, but Grim plans to give them a short sharp shock. The two are, of course, not mutually exclusive.
