Lyle is left in charge of the office and cat-sits for Mrs. Compton, as well, in Gloria's absence on holiday with Sidney, getting himself into hot water when he and Gloria's enterprising little boy, Scott, inadvertently advertise a free will-making service and are inundated with clients. Peter has gone to Cambridge to help Professor Barkway clear up a matter. Another lecturer, biologist Mary Goodyear has died and Barkway believes her valuable research papers should be published but her partner, Janet Cramer, is blocking him, stating that Mary's will left her the papers. Peter discovers that this is a lie and Janet is protecting Mary, who killed herself as she thought her research was in vain. But Barkworth has an ulterior motive as the dead woman's effects contain love letters between her and himself, unknown to Janet. He believes this will prevent his being made Master of the college but the committee instate him anyway.
