Angel Street is the story of the Manninghams who live on Angel Street in 19th Century London. As the curtain rises, all appears to be the essence of Victorian tranquility. It is soon apparent, however, that Mr. Manningham, a suave, handsome man, is slowly driving his gentle, devoted wife, Bella, to the brink of insanity with an insinuating kindness which masks more sinsister motives.
While he is out, Mrs. Manningham has an unexpected caller, amiable, paternal Inspector Rough from Scotland Yard. Rough is convinced that Manningham is a homicidal maniac wanted for a murder committed fifteen years earlier in this very house. Gradually the inspector restores Bella’s confidence in herself and as the evidence against Manningham unfolds, the author has built and sustained some of the most brilliant, suspenseful sequences in modern theatre.
