E. Phillips Oppenheim 
Prodigals of Monte Carlo [EPUB ebook] 

This novel has an intriguing start, as handsome and charming Sir Hargrave Wendever gets a nasty shock from the doctor. He decides to do some good with his money in the time he has left, and offers a penniless young woman a free holiday at his villa, with no strings attached. That is just the beginning of a whole series of romantic complications… Arguably Oppenheim's best book!
