From a Book: Enchanted as Sin

For [the white witch] knew, though Edmund did not, that this was enchanted Turkish Delight and that anyone who had once tasted it would want more and more of it, and would even, if they were allowed, go on eating it till they killed themselves.

-from The Lion, the Witch, and the Wardrobe (Book 1 of the Chronicles of Narnia) by C.S. Lewis, Loc 363
