Three Loves Has Nancy with Janet Gaynor and Robert Montgomery. Successful New York novelist Malcolm Niles finds his latest romantic relationship moving unexpectedly and disagreeably toward marriage. In order to escape the noose he embarks on a nationwide book signing tour. At a small southern book shop he meets homespun Nancy Briggs who is scheduled to be married that same day. They do not hit it off. Niles receives a telegram from his publisher that his fiancée-to-be, Victoria, has left town and it is safe to return to New York. Nancy receives a letter from her actual fiancée, George, who is supposed to be arriving from New York, saying that he will not be attending the wedding. Both Nancy and Niles hop the first train to New York and run into each other in the dining car where Nancy continues to annoy Niles.
Unable to find George in New York, Nancy finds herself at loose ends. Upon arriving at his welcome home party Niles discovers that Victoria has not left New York after all. Niles offers to let Nancy stay in his apartment while insinuating to Victoria that he is now inextricably romantically involved with her, causing Victoria to move on to her next prospective husband. Niles's publisher, Robert Hanson, lives in an adjoining apartment and passionately avails himself of Nancy's willingness to cook. At some point as Niles tries to be rid of Nancy she moves in with Hanson and he phones in meal orders from the office like he is ordering room service.
Robert's gustatory passion turns into romantic passion, and faced with this Niles finally realizes that he loves Nancy as well. To complete the "Three Loves" original fiancée George shows up as well.
This movie was aces! Robert Montgomery was both cool and perturbable. I always enjoy a good dining car scene. In this case it was the first instance of a running gag with Janet Gaynor losing her purse only to find that it was with her the whole time.
