Mrs. Wentworth and her daughter Cecile are living at one of the fashionable hotels in the city. James Davidson, who is engaged to Cecile, has agreed to join a theater party with them. At the last minute he sends word that business will detain him and he will be unable to go. Cecile is inconsolable and refuses to go to the theater with the rest of the party. She is so upset over the disappointment she gets a severe headache and decides to retire. In her pink pajamas she is about to go to bed when she decides to write "Jamsie," giving him to understand she is not at all pleased with his conduct. She sneaks out into the hall, puts her letter in the drop and hastens back to her rooms, to find the door has sprung locked.
