glad I picked this up as an audiobook, because otherwise it would be a bit of a struggle to make it past the first few chapters. when douglas describes the "unsub's" motives, psychology, or the minute details of each case I feel the minutes fly by, but the pace stops dead in its tracks anytime he talks about anything else. if I wasn't already motivated to read this after rewatching netflix's excellent mindhunter series--which is so much more compelling than this particular work--it's very likely I would have DNF'd it.
