Jack and Bella Manningham's home on Angel Street was the scene-many years ago-of Alice Barlow's murder, whose valuable jewels have never been found. Now Bella's belongings are disappearing and nothing seems to make sense. Is she falling victim to her mother's mental illness, or are other forces at work? When an unexpected visitor arrives with surprising news from Scotland Yard, shadows of uncertainty are cast on their domestic tranquility. The original Broadway production in 1944 spooked and delighted audiences for over 1300 performances. It remains one of the longest running plays in Broadway history.
