Plot summary Synopsis Harry Sandwith, a sixteen-year-old English boy, is sent to live in France with the Marquis de St. Caux, a friend of a French nobleman Harry's father once served. The marquis is impressed with the English system of schooling and believes that his two sons, Ernest and Jules, will benefit from the influence and friendship of an independent and manly English boy. Harry, who is an undistinguished, average student at Westminster School, is eager for the opportunity to live in France, which he believes will create greater opportunities for him when he joins the British Army. Harry sets off for Paris in 1790 with the intention of living with the St. Caux family for the next two to three years. Harry is escorted to the marquis's chateau near Dijon. He meets the marquis and his wife, along with their two sons, Ernest and Jules, and three daughters, Marie, Jeanne, and Virginie. The marquis is impressed by Harry's confidence and self-possession in such an unfamiliar environment, but the rest of the family remains unconvinced and mocks his strange mannerisms and rough appearance. Their attitude changes, however, after Harry succeeds in killing a rabid dog that attacks Jeanne and Virginie. They begin to accept Harry as a member of the family, and Harry and Ernest become close friends, hunting and adventuring together and even managing to kill the Demon Wolf that long terrorised the communities surrounding the chateau. During the years of Harry's life at the chateau, the French Revolution continues to progress throughout the country. As a member of the French nobility, the marquis and his family are loyal to King Louis XVI and are deeply troubled by the growing violence and unrest in Paris and the countryside. After the royal family unsuccessfully attempts to flee Paris, the marquis decides to move the St. Caux family to Paris to support the king and to avoid the growing unrest of the peasants living in the countryside. The situation in Paris continues to deteriorate and soon an arrest order is made for all the members of noble families. The marquis and marquise submit
