The rubies are famous because they were among the first to be sold abroad after Britain conquered Burma in the 1850s; after all these years, Betsy Fieldingley has had to sell them in order to pay off her debts. But disaster strikes when the rubies are found to be fakes, and Jo finds herself under attack from all sides: Ivan and Miri are furious with her, and Tim Fieldingley, Betsy’s rather likeable grandson, blames her, unfairly, for the slight to the family name . . .
