Phineas Finn is the sequel to “Can you Forgive Her?” and the second novel in Trollope’s Palliser series. The eponymous hero is a young Irishman who becomes a member of the English parliament. Trollope aspired to become an M.P. himself, and he ably describes the workings of the English political scene. There is also a love interest, as the somewhat inconstant Phineas courts three different women: his Irish sweetheart, Mary Flood Jones; Lady Laura Standish, the daughter of a prominent Whig politician; and a lovely heiress, Violet Effingham.
