Connie calls Glossop's office, finds Halliday is an imposter and ejects him from the castle. Trout and Vanessa meet up in the night to steal the painting, but Chesney fails to turn up, having crashed his car on the way. The two realise they love each other, and leave next morning to get married. Connie insists that Dunstable write to Vanessa proposing marriage; but the letter is intercepted by Gally, who shares with Dunstable his knowledge that Vanessa is not really an heiress, and makes the Duke allow the wedding of Linda and Johnny in exchange for the return of his letter, under threat of a breach of promise suit if it were to reach Vanessa. Connie is recalled to America by her husband, and the Duke returns home, leaving Emsworth once again master of his domain.
