The Voyage of the Dawn Treader
There was a boy called Eustace Clarence Scrubb, and he almost deserved it. (1.1)
"I do not know what it means. But the spell of it has been on me all my life." (2.23)
"Did you know I was there all the time?"
"Well, of course I knew when I let the Duffers make themselves invisible that you would be coming along presently to take the spell off. I wasn't quite sure of the exact day." (11.11-12)
