The Young Visiters or Mister Salteena's Plan is a 1919 novel by English writer Daisy Ashford (1881-1972). She wrote it in 1890 when she was nine years old and part of its appeal lies in its juvenile innocence, and its unconventional grammar and spelling. A great success, it sold around half a million copies during the twentieth century and has been adapted for film, television, and as both a stage play and a musical.
Alfred Salteena, an "elderly man of 42", has invited 17-year-old Ethel Monticue to stay with him. They receive an invitation to visit Alfred's friend, Bernard Clark, which they readily accept. Bernard is "inclined to be rich". Shortly after their arrival, Ethel and Bernard become attracted to each other.
Alfred seeks Bernard's advice on how to become a gentleman. Bernard is doubtful that this can be managed, but writes an introduction to his friend the Earl of Clincham. Alfred excitedly rushes off to London to visit the Earl, leaving Ethel alone and unchaperoned with Bernard.
Lord Clincham lives, as many other aristocrats do, in "compartements" at the Crystal Palace. He agrees to assist Alfred and instals him in a subterranean "compartement", along with other "apprentice gentlemen". He invites Alfred to accompany him to a reception hosted by the Prince of Wales (the future King Edward VII), introducing Salteena as Lord Hyssops. The Prince is impressed, and promises to assist the trembling and overjoyed Salteena.
Bernard and Ethel fall in love and marry. Devastated by these events, Salteena marries a maid-in-waiting at Buckingham Palace. Lord Clincham also marries, but not very happily.
