First appearance: the adventure of the western star
As a supporting figure in Poirot Investigates, Lady Yardly is not background color—the story leans on what they do once the chapter opens.
Lady Yardly belongs to the world of titles and country houses that the Western Star case cuts across, her diamond set against Mary Marvell's in a contest of possession and prestige. She is caught between the discretion her rank demands and the danger circling the stone, a woman whose composure may conceal more than it shows. Her stake in the jewel makes the theft personal, widening the mystery from a single actress's panic to a clash of two very different worlds.
