Quit: The Big Con by David W. Mauer, 1940 (original), 1999 (reprint), 0385495382.
History of cons and con men from about 1900 onward. The writing is dated. The author names famous con men as if I should know them. Maybe people at the time did. Descriptions of the cons were a little confusing - I suppose that is fitting.
I tried to keep going but lost interest.
