Bitter Sweets (1928)

A young heiress returns from Europe to find herself an impoverished orphaned Stone broke, she takes work as a confidential aide to a private detective. It seems that a lady's letters are being held by a cad, but the girl detective gets the man she's after, and one she isn't after. Hence the title. Humorless but quite convincing melodrama.
