More specifically than that:

You can find the Cleckley book in question online in various places like http://libgen.info/view.php?id=23550 ; even if you aren't that interested in psychopathy per se or judging how well the OP person fits Cleckley's characteristics, it's still a fascinating & worthwhile read, I think (my review: http://www.goodreads.com/review/show/373031205 ).

The reference for my claim about treatment being inefficacious: http://dl.dropbox.com/u/85192141/2006-harris.pdf “Treatment of psychopathy: A review of empirical findings” Harris & Rice 2006

And you can find quotes on other topics from the academic literature in http://lesswrong.com/lw/fzy/notes_on_psychopathy/
