The presence of a striking and mysterious blond woman among the mourners at Lord George Frampton’s funeral surprises his family. When the young woman, Phaedra Chancellor, reveals that she is in fact Lord Frampton’s daughter and that she has inherited the valuable Frampton suite of sapphires, surprise gives way to shock. But Phaedra’s effervescent nature soon wins over the Frampton family. Lady Antoinette Frampton finds in Phaedra the daughter she never had, while David, the new Lord Frampton, is utterly charmed as Phaedra manages to thaw the heart of Margaret, the Dowager Lady Frampton. But Roberta, the wife of Lord Frampton’s second son, is the only one not convinced and sets out to discover the truth about who Phaedra really is.
