"I learned many things in prison that were terrible to learn, but I learnt some good lessons that I needed."

Oscar Wilde wrote the above quote to his friend Carlos Blacker, who escaped England for France in 1890 after being falsely accused of being a card cheat. Wilde himself, the author of The Picture of Dorian Gray and The Importance of Being Earnest, was accused and imprisoned for "acts of gross indecency," essentially for having homosexual relationships with multiple men.
