That moment you find a copy of a book for $2 in a bookshop when the cheapest copy available on the internet is $63. That.
Let me correct that. The only copy available on the internet is $63 . . . and, for all I know, it's in worse condition than the copy that I just picked up.
The copy I just picked up is falling to bits as I write and won't survive a second reading - like I ever read a book a second time - but I never thought I'd see a copy of the this most wanted book this side of winning the lottery. (And, trust me, I looked for it.)
