Norris and her husband, Sully, are at a popular library conference in Chicago to hear book restoration specialist Brooklyn Wainwright give a keynote address. After the lecture, Lindsey looks under her seat and finds a tote bag containing a first edition of Patricia Highsmith's Strangers on a Train, inscribed to Alfred Hitchcock. Brooklyn determines the novel is one of a kind and quite valuable, so Lindsey and Sully return the book to the conference director, not wanting to stir up any trouble.
