Based on the cult mystery novels by author, journalist and royal biographer Tim Heald, this quartet of light-hearted whodunits stars David Horovitch as a bungling but diligent Department of Trade investigator. Featuring guest performances from Patrick Troughton, John Le Mesurier, Glynis Barber, Peter Jeffrey and Elizabeth Spriggs, among many others, this set contains all four stories: Unbecoming Habits, Deadline, Let Sleeping Dogs Die and Just Desserts.
