The House of Whispers (1920)

Spaulding Nelson moves into an apartment after his uncle has been driven from it by the sounds of screams and whispers. Upon undertaking an investigation, he meets neighbor Barbara Bradford, whose sister Clara is being tormented by the recurring sounds of her dead husband Roldo's voice. Roldo is actually alive and an accomplice of Henry Kent who built "the house of whispers" and riddled it with secret passageways which enabled him to gain entry to the apartments. Spaulding locates the secret panel doors, but is arrested on suspicion of murdering actress Daisy Luton, a victim of Roldo. Eluding the detectives, Spaulding escapes through the panel and down a secret passageway where he corners Kent, Roldo and Nettie Kelly, Roldo's first wife. After Nettie confesses, Clara is freed to marry her fiancé and Barbara accepts Spaulding's proposal.
