G. A. Henty 
Saint Bartholomew’s Eve 

Historical novel, set in 16th century France, focusing on the conflict between Protestants and Catholics. The Preface begins: 'It is difficult, in these days of religious toleration, to
understand why men should, three centuries ago, have flown at each others’ throats in the name of the Almighty; still less how, in cold blood, they could have perpetrated hideous massacres of men, women, and children. The Huguenot wars were, however, as much political as religious. Philip of Spain, at that time the most powerful potentate of Europe, desired to add France to the countries where his influence was all powerful; and in the ambitious house of Guise he found ready instruments.’ According to Wikipedia: 'George Alfred Henty (8 December 1832 – 16 November 1902), referred to as G. A. Henty, was a prolific English novelist, special correspondent, and Imperialist born in Trumpington, Cambridgeshire, England. He is best known for his historical adventure stories that were popular in the late 19th century. His works include Out on the Pampas (1871), The Young Buglers (1880), With Clive in India (1884) and Wulf the Saxon (1895).’
