When London Burned — a Story of Restoration Times and the Great Fire [EPUB ebook] 

Cyril Shenstone, a son of a nobleman who lost his estates during the troubling times of the Commonwealth is the hero of this story. Instead of hanging idly about the court seeking favors, he is determined to maintain himself by honest work. During the Great Plague and the Great Fire, which visited London with such terrible results, Cyril Shenstone brought help to the panic-stricken inhabitants. This tale has rich variety of interest, both national and personal, and the hero is an eng lad of the noblest type wise, humane, and unselfish.
