”Waters of the Moon,” written by N. C. Hunter, was a popular success in London during the 1950’s, in those seemingly unruffled days just before John Osborne and a host of other angry young men began vandalizing the theater’s traditional British drawing room. Hunter placed his characters in a small, shabby-genteel hotel in Devonshire, an establishment catering to permanent guests who are, in different ways, down on their luck. The hotel is run by hard-working Mrs. Daley and her two children, feisty Evelyn and consumptive Johnny.
