...One Third of a Nation... is a 1939 American drama film directed by Dudley Murphy and written by Oliver H.P.

Cortlant is told by his business manager (Percy Waram) that he owns the building where the fire occurred.

The local district attorney investigates the fire, and tells Mary that the tenement's age means it was exempt from modern building safety codes.

Crippled and suffering from delusions that the building is talking to him, Joey vows revenge on the tenement.

Mary meets with Cortlant, and convinces him to turn his decrepit tenements into public housing and rebuild them.
