13 Shocking Secrets You'll Wish You Never Knew About Lemony Snicket is a promotional pamphlet containing thirteen "secrets" about Lemony Snicket; the final secret is found by decoding a puzzle. It was distributed through the HarperCollins AuthorTracker mailing list and on the Lemony Snicket website in promotion of The End. The day after the pamphlet was published, HarperCollins issued a press release revealing that Lemony Snicket had finished writing The End, the final book in A Series of Unfortunate Events. The final secret is also echoed towards the end of the Dear Reader letter for The End.
