Mr. Scobie's riddle

Plot

Mr Scobie's arrival at the nursing home of St Christopher and St Jude-and into the clutches of Matron Hyacinth Price-is accidental. Self educated and still preserving the gist of idyllic memeory and wish, Mr Scobie stands apart from the others. For long term resident and eccentric, Miss Hailey, he represents a kindred spirit; for Matron Price-a lady of questionable practices-the latest victim...But unwittingly Mr Scobie has some recourse-his very simple riddle. Its answer-an ancient commonplace-jolts Matron Price.Yet it is Mr Scobie's nephew, Hartley, and the group of nocturnal poker players, who ultimately change Matron Price's establishment.
