The Expert at the Card Table by S.W. Erdnase

It was written over one hundred years ago (1902) by a mysterious author who many, including the late Martin Gardner, have been obsessed with identifying.

I originally bought it years ago to learn sleight of hand techniques but found that the book increased my ability to detect subterfuge in many areas and not just crooked card games. There is something special about the book.
