Mark Hawkins is an engineer and a loner, who has always resented his adventurer-archaeologist brother, Dick. But when Dick vanishes, allegedly dead in a climbing accident, Mark starts investigating the site his brother was excavating, a Cistercian monastery, and meets three strange souls who were the last to see his brother alive.

Among them is Dr Merrion, a specialist in medieval archaeology. As Mark pokes around the woods surrounding Merrion's home, he begins to feel that sinister forces are at play in Dick's death.
