Cracker: A New Terror (2006)

After living in Australia for the past decade, Fitz and Judith return to Manchester in 2004 for their daughter Katie's wedding. Drinking too much at the reception, Fitz stumbles through a rambling toast, which only embarrasses the bride. Instead of spending time with his grandson, son of his married son Mark, Fitz opts to join in the investigation of a serial killer who has an apparent dislike of Americans in the wake of the U.S. Invasion of Iraq.
