When Jane Minton arrives at Dome House as a secretary-housekeeper, she finds herself sharing the comfortable country home of four attractive young people. Their handsome widower father, Rupert Carrington, too occupied with his London business to see very much of them, merely provides for them generously and leaves them to cultivate their talents -- which they energetically do. Richard, the eldest, is a composer; Clare, whose true talent (if it can be called that) has never disclosed itself, attempts to paint; Drew is collecting material for a novel to be set in the Edwardian era; and Merry, still at school, already works hard towards a stage career. Jane Minton, warmly welcomed into this happy household, feels her luck is too good to be true. And it is certainly too good to last. The delightful private world of Dome House is fated to break up.
It is Jane who learns from Rupert Carrington that he is in danger of prosectuion for fraud and must leave England. He asks her to break the news to his children -- who must now fend completely for themselves -- and do what she can to help. She is very willing to, for his sake as well as theirs, as she is greatly attracted by him. What happens then makes an engrossing and unpredicable story, for the Carringtons are not usual young people, and it is, perhaps, their own basic originality which draws to them unusual adventures, in which humor and more than a touch of strangeness are often inextricably blended.
