Hired by millionaire businessman Malcolm Capshaw to search for a fabled historical artifact in the shadows of Glastonbury Tor, Joe Cutler and his team from Strata Survey Systems are drawn into a web of sex, lies, deceit, murder, and betrayal. The artifact is revealed to be bogus, and the real purpose of their search is slowly exposed. A menacing background presence, in the form of an old-established London crime family, appears to display an abnormal interest in the goings-on in the ancient town where Christianity laid its roots in England. There, aided by the enigmatic and flamboyant university professor Lucius Doberman, Joe and his team must solve the mystery of Glastonbury before the sinister historian Walter Graves makes the discovery that could cost him and the whole team their lives.
