Secrets of the Night is a 1924 American silent film directed by Herbert Blaché and made at Universal Pictures. The black-and-white “murder mystery-melodrama comedy” stars James Kirkwood Sr., Madge Bellamy, and ZaSu Pitts. It was adapted from the play The Nightcap written by Guy Bolton and Max Marcin. The film was thought lost until a print of the film was rediscovered in a basement in Mississauga, Ontario, in 2017.
