Nancy, Bess, and George encounter a troublesome stray terrier on their way to the opening festivities of a new park and recreation complex in River Heights. The terrier grabs the handbag of one of the guest speakers and loses it in a nearby pond. Nancy helps groundskeepers retrieve the handbag and uses the notes found inside to prompt the nervous speaker during her address. She also finds a mysterious personal ad in the handbag. In a casual observation, the "clubwoman," a Mrs. Owen, tells Nancy about a statue on a deserted seaside estate.
