Thanks, the Lady of Shalott just reminded me of Agatha Christie's The Mirror Crack'd From Side to Side. The quote shows
Out flew the web and floated wide-
The mirror crack'd from side to side;
"The curse is come upon me," cried
The Lady of Shalott.
The next quote:
He said, "She has a lovely face;
God in his mercy lend her grace,
The Lady of Shalott."
