When an unknown author (the name he put on the book, S.W Erdnase appears to be an alias) published his book on card cheating, few at the time could predict its effect on card magic and cheating everywhere. In this blog (from now on) I hope to detail my work on Erdnases's writings and perhaps add details, tutorials and comments on my own work and that of Erdnase. I would also like to write about legends of card magic (the likes of John Scarne, Dai Vernon and Ricky Jay).
