Plot
Maggie Walsh and her boyfriend Pete Danner are interior decorators from Los Angeles. Maggie receives a large financial retainer from an anonymous client in Britain for an unspecified piece of work. They are reluctant to abandon their current client in California, but are released when that client dies suddenly under mysterious circumstances. Using their pre-paid airfare, they travel to England; soon after, they are involved in a traffic collision with a chauffeur-driven Rolls-Royce. The passenger and owner, Jason Mountolive, invites them to his rambling country estate, Ravenhurst, where they are greeted by Nurse Adams.
They find that Mountolive has also invited the five potential heirs to his financial estate, all public figures with notorious reputations. The other guests explain that they have been summoned because Jason is dying, "wasting away" above the stairs. Maggie is astonished to hear this because Jason seemed vigorous just minutes earlier.
