Doctor Thorne (1858) is the third novel in the "Barsetshire" series. Doctor Thorne adopts his niece Mary, keeping secret her illegitimate birth as he introduces her to the best local social circles. There she meets and falls in love with Frank Gresham, heir to a vastly mortgaged estate; yet Frank is obliged to find a wealthy wife, jeopardizing Mary's happiness until fate extends an obliging hand. Where fiery passion fails, understated English virtues of patience, persistence and good humor could yet prevail in this most appealing of Trollope's (1815-82) comedies.
