Mr Darcy demonstrates his prowess to Miss Bennett at Freestyle Disco; there's an introduction to Glucozade Port, the world's first alcoholic isotonic drink; and a carnivorous man at a vegetarian dinner party points out that the cat looks lean and gamey. Plus a new adventure for drunken super-sleuth Sir Digby Chicken-Caesar; an unnecessarily honest best man; and David and Rob find themselves in an awkward situation with the Queen.
