Zenith, British mass market paperback Originally published in 1968, this is an undated paperback reprint (about 1980). "Peter Saxon" was a house name used by publishers for a line of horror novels, including the cult-classic series, The Guardians. This novel is one of six Guardians books, and the actual author of this one is reported to be Ross Richards. The series consists of two unnumbered novels, this one (A) and "The Curse of Rathlaw" (B). Later, Berkley released four numbered 1) The Killing Bone, 2) Dark Ways to Death, 3) The Haunting of Alan Mais, and 4) The Vampires of Vinistere. The books center around a team dedicated to fighting supernatural evil - and the evil is truly supernatural. The Guardians are headquartered in "swinging London with its miniskirts, sports cars, exhaust fumes and discotheques." The building they occupy, however, is tucked back along some quaint (but still dark) alley called "Start Passage." It is haunted, often deceptive, and frighteningly mysterious even to some of the Guardians themselves.
