By Alan Harrington. The author is a Harvard-educated novelist; the book is a more literary than scientific look at the coming "Age of the Psychopath."
It's in pretty good shape for a 50-year-old paperback: a previous owner's name on the flyleaf, some shelfwear and page toning, and the spine is cracked -- but the pages are tight. There's some underlining as well, but this was and is likely a research copy.
