Don't Tell Everything (1927)

Max and his son Asher are invited to a party, where Max meets a rich widow, but Asher keeps annoying all of the guests, so Max refuses to speak to him. 10 days later he has married the widow, but hasn't told her about Asher. Asher doesn't like the situation either, and enters the home disguised as the new maid, that leeds to a growing suspicion of his step mother, who has her own little secret.
