Which of these authors wrote a book called "The Kreutzer Sonata"?

"The Kreutzer Sonata", first published in 1889, and taking its name from the musical composition of the same name by Ludwig van Beethoven, is a work by the legendary Russian author Leo Tolstoy, most famous for "War and Peace" and "Anna Karenina".

It is told in a form popular at the time: the framework narrative, with the first narrator being a passenger in the same train as the protagonist, Pozdnyshev

It is not surprising that the work aroused considerable controversy at the time, as it tells a tale of murder, jealousy, and adultery and even, incidentally, contains a reference to contraception!

Pozdnyshev's wife has an affair with a violinist, and they plan the eponymous piece of music together. When Pozdnyshev returns and finds them enjoying considerably more than the joys of music, he takes a silver dagger and seeks to wreak vengeance. His wife is killed, but the violinist survives. But given his wife's adultery, he is acquitted of murder, and thus shares the train journey with the original narrator.

The book's controversy went beyond the bounds of Russia, and no less a person than Theodore Roosevelt described Tolstoy himself as a "sexual moral pervert". But that notwithstanding, although not as popular as his two great novels, the work has remained in print ever since!
