The Forbidden Room is a 1914 American silent drama film directed by Allan Dwan and featuring Murdock MacQuarrie, Pauline Bush and Lon Chaney.
[5] Fulfilling a promise made to his mother on her deathbed, Dr. James Gibson locates his sister Pauline who has run away after giving birth to an illegitimate child.
The niece is arrested and charged with murder, but Pauline is later found dead in her room, clutching a watch that was stolen from Morris, and the young girl is acquitted.
"[6] Moving Picture World wrote "This melodrama depends upon the powerful, thoroughly human situations involved rather than on any sensational, hair-raising incidents.
Miss Bush enacts a dual role...her work in this picture is wonderfully impressive, realistic and human.
