What No Man Knows
Norma Harvey, a newspaperwoman who devotes much of her time to relieving the sufferings of slum children, still loves her childhood sweetheart, Craig Dunlap, a lawyer who tries to cover up his wife's kleptomania by bribing a witness at her trial. Dunlap, however, is exposed and disbarred. While working in the slums, Norma encounters him in a disreputable dive and takes him to her home along with little Mazie, a blind orphan.
