1940. Hitler is about to employ the secret arts of dark and evil witchcraft to destroy England. It is the mission of John Graham, colonel in British Intelligence, to stop the onslaught of evil with an extraordinary strategy and defies all the rules of modern warfare: unite the different witches' covens throughout England, drawing upon powers that reach back through the centuries in a ritual of awesome sacrifice on the night of August 1st - the magical Lammas Night. N.B. It has been determined in recent years that the great rite to keep Hitler from setting foot on English soil was a real event and there were still people living who admitted participating in it. Dennis Wheatley, noted occult author and who during the Second World War was a member of the London Controlling Section which secretly coordinated strategic military deception and cover plans, is likely to have been involved in the organisation of the event.
