Marjorie Hunt, an old friend of Mrs White, comes to stay at the Grange. Unfortunately for her, she is a psychic and unwisely gives a Tarot card reading for some of the regulars on the evening of her arrival... Miss Scarlett has damaged her car that afternoon, and Mrs Hunt knows all about it - and maybe more. Green is having an affair with a married woman in the village. Mrs Peacock is preparing to burn down the Grange for the insurance money. Mustard feels guilty about a little matter of some missing army property. Plum's latest invention has got him into hot water. And Mrs White has a dark secret. All too predictably, Mrs Hunt does not live to see the next morning.
