Heavyweight Notre Dame professor Roger Knight and his p.i. brother Philip investigate a baffling puzzle when some extremely rare literary documents go missing in the fifth installment of this smart academic mystery series. Complicating matters for the brothers are the impending nuptials of some dear friends, Larry Morton and Nancy Beatty, which hit a snag. When Larry was an undergraduate at Notre Dame he made a prudent but overly optimistic reservation to marry his freshman sweetheart, Dolores Torre, in the popular campus rectory six years in the distant future. Their relationship didn't last, and now Larry wants to use the reservation to marry Nancy. Unfortunately, his old girlfriend Dolores has a similar plan.
