Through both his writing and his life, Tolstoy became known as a troubled man who devoted himself to the search for life's meaning.
Frederick and Nataliya Felt were attending the Laurel Ward of the Silver Springs Stake in Washington, D.C., when a Russian member told them that Tolstoy's library contained a copy of the Book of Mormon.
Their initial intrigue turned into a quest to discover its origin story.
"I was surprised to learn that Tolstoy had a Book of Mormon," Frederick said. "I wondered how (he had obtained it) since the church didn't have missionaries in Russia during his lifetime."
Frederick determined there had to be some kind of inscription on the inside cover and that the information was a "valuable fragment of church history."
Nataliya had a personal interest. She was born in Moscow and knows both the language and the country's rich literary history.
