When young doctor Carl Foster hears the celebrated opera singer Rosetta Rosa perform in London, he is instantly captivated — and soon finds himself drawn into a web of hypnotic obsession, jealousy, and unexplained deaths that trail in her wake. Arnold Bennett's 1907 novel blends gothic romance with early psychological suspense, asking whether the "ghost" that haunts Rosa is supernatural, or something far more human. A rare early work from the author of The Old Wives' Tale, full of fin-de-siècle atmosphere and slow-building dread.
