At Christmas 2010 ITV broadcast an adaptation of "The Secret of Chimneys", set in 1955 (but harking back to a ball in 1932), which, unlike the novel, imported Christie's perennial Miss Marple (Julia McKenzie) and made a number of other changes. Dervla Kirwan, in her late thirties, played Bundle, who, though still the daughter of Lord Caterham, was cast as the sister of 23-year-old Lady Virginia Revel (Charlotte Salt), an unrelated character in the original story. Of the two, Lady Virginia appeared to have more in common with the Bundle of the novels. The "Radio Times" observed that this production was "classic Agatha Christie, even though it's only distantly related to her original ... purists will be utterly flummoxed - and the plot has more holes in it than the murder victim".
