"Heart" is a gripping narrative nonfiction podcast that unravels the eerie true story of Sonny Graham, a heart transplant recipient who married his donor's widow—only to die by suicide, mirroring the exact fate of his donor, Terry Cottle. Produced by Plan B and Blanchard House as an Apple Original, the series blends investigative journalism with deep emotional storytelling, exploring themes of grief, fate, cellular memory, and the unexplained psychological phenomena sometimes reported by transplant recipients. With a tone that's equal parts haunting mystery and human drama, the show examines court records, family testimonies, and medical speculation to probe whether the men's shared deaths were coincidence or something more mysterious. Ideal for fans of true crime and psychological thrillers, listeners drawn to science-meets-mystery narratives, and those fascinated by stories of love, trauma, and the unexplained will find this series a compelling, binge-worthy listen. Its cinematic pacing and investigative depth set it apart from typical true crime fare, offering a meditation on identity, memory, and whether the heart truly can carry more than blood.
