I was sad to hear that George C. Chesbro, author of the Mongo mysteries, has passed away, as noted at Confessions of an Idiosyncratic Mind, The Rap Sheet and the author's official site. With his dwarf protagonist, Chesbro brought something unique to crime fiction, a willingness to mix elements of the paranormal with the traditional gumshoe mystery, well before "The X Files" and its many imitators.
I started reading Chesbro with "The Beasts of Valhalla." (C'mon, look at that cover! How can you not want to pick it up?) It's an astounding mash-up of Wagner, "The Lord of the Rings" and a mad-scientist science fiction plot. I highly recommend it and its two immediate follow-ups, "Two Songs This Archangel Sings" and "The Cold Smell of Sacred Stone."
A few years ago Clayton Moore wrote an excellent column about Chesbro for Bookslut. It's worth reading now as an eloquent remembrance.
