I'm trying to find the name and author of a classic poem. At least, I
recall it as a poem.
It is a monologue about a man who is showing off a painting of his former
"Lady" or "Mistress" (one or the other), and he is talking about her
smile,
which he loved, but she shared that smile with everyone, and so we
discover
that he had her killed.
Thank you.
