It's a blog! Mainly of book reviews.
Keller is a stone cold killer (as discussed at length when he goes to therapy). So why is he a sympathetic character? I think it must be his amusingly hapless attempts to try to connect with the rest of humanity by fantasising about small-town life, getting a dog, even taking up stamp collecting! Whatever the reason, Keller is an interesting enigma who makes murder look easy (suspiciously easy, I'm pretty sure the author is giving him a big break) in this sequential set of shorts, originally published in Playboy.
