In Simon R. Green's AGENTS OF LIGHT AND DARKNESS (4), you don't want to meet the things that go bump in the Nightside. The hero, John Taylor, has returned to that world at the secret heart of London, inhabited by monsters, demons and some unusual humans. With a gift for finding things that are lost, John is hired by an undercover priest to find the Unholy Grail, the cup used by Judas at the Last Supper. This grail corrupts, but it has amazing powers and is avidly sought by both good and evil creatures—who soon realize John can lead them right to it. Green's writing style is a mix of creepy and matter-of-fact, perfectly suited to his dark-tinged story. Supernatural and religious elements combine in the Twilight Zone-like setting, biblical stories come to life and angels go to war. The ending twist is somewhat telegraphed but doesn't diminish the overall enjoyment. (Oct., 240 pp., $6.50)
