The Man Upstairs is a 1926 American silent comedy film directed by Roy Del Ruth and starring Monte Blue.
[2] As described in a film magazine review,[3] adventurer and traveler Geoffrey West has a passion for "The Agony Column" of the newspaper, which lists advertisements for missing friends and relatives, and uses the personals to get acquainted with Marion Larnard, whom he sees in a London hotel.
She invites him to write her a daily letter for five days to prove whether his acquaintance is worth cultivating.
Taking this as his cue, in these letters he begins a mystery story to show her that he is an interesting fellow and leads her to believe that he has murdered Captain Fraser-Freer until she understands that it was intended as an elaborate joke on her.
Marion then, with the aid of the army officer who pretends to be dead, turns the table on Geoffrey and gives him a scare in return by having him arrested and put in jail.
