The Diamond Pin

The wealthy and notoriously difficult Ursula Pell is found dead in her locked chamber, and the list of suspects reads like a family tree of resentment. Her niece Iris and nephew Winston, both poised to inherit, discover themselves immediately under suspicion. But Ursula's talent for practical jokes and pointed cruelty made enemies of nearly everyone who knew her, and as the investigation unfolds, every relative seems to have something to hide. Wells constructs the classic locked-room puzzle with characteristic wit and cleverness, making the reader question not just who did it, but how it was even possible. The family dynamics are razor-sharp: greed, old grudges, and buried secrets rise to the surface as the investigation progresses. For fans of golden age detective fiction, this is a devilishly constructed puzzle that rewards careful attention.
