The Sorrows of Satan is an 1895 Faustian novel by Marie Corelli. It is widely regarded as one of the world's first bestsellers - partly due to an upheaval in the system British libraries used to purchase their books, and partly due to its popular appeal. On the surface the plot follows the story of a penniless, starving author called Geoffrey Tempest. So poor that he is behind on his rent and can barely afford light in his room, he receives three letters. The first is from a friend in Australia who has made his fortune and offers to introduce him to a good friend who might be able to lift him from poverty. The second is a note from a solicitor detailing that he has inherited a fortune from a deceased relative. The third is a letter of introduction from a foreign aristocrat called Lucio, who befriends him and proceeds to be his guide in how to best use his newfound wealth.
