Do I Twist, Do I Fold, by rosa_acicularis.

"Will you walk into my parlor?" said the spider to the fly;
"'Tis the prettiest little parlor that ever you may spy.
The way into my parlor is up a winding stair,
And I have many curious things to show you when you are there."

For who goes up your winding stair can ne'er come down again."
