I was reading an article this morning about a South African man who, while on holiday in Ireland, found an American first edition of Wuthering Heights at a flea market for €3 (about $4.27).  Realizing the value of the book, he brought it back home to South Africa and promptly sold it for over 77,000 rand (equivalent to more than €8,000 or $11,000)—quite the souvenir! The article quoted ILAB member David Cunningham of Cathach Books Ltd. in Dublin, who commented that this was likely the only first edition of Wuthering Heights in the country.  He went on to say that "you just don't know how books turn up and how it arrived in this country, but that's the nature of books—you can find almost anything anywhere."  This quote got me thinking about all the interesting stories book hunters everywhere must have.  What has been your most interesting and/or profitable find?
