Advised to leave the Planning Department as a disruptive influence, Arnold Landon found his new job in the Department of Antiquities and Museums got off to a difficult start: he had to rewrite a brochure on the Northumberland pele towers for a colleague who had mysteriously dis¬appeared. The reappearance of his colleague, now suspected of the murder of his wife and her lover, and hints of occult practices, only drew Arnold further into a network of secrecy and death that involved ancient religious beliefs under the mantle of the Knights Templar. But the fourteenth-century past was to mingle with the murderous present once more before Arnold discovered the cryptic secret of the de Bohuns. And by that time the murderer had him entombed, and Arnold was in danger of his life.
