For his second novel, Dr. Roy goes to the Mull of Kintyre - whose peace and beauty contrast strangely with dark and far-reaching events. How is the thin borderline between reality and illusion defined? To a car-crash victim - a space scientist -recovering in a neurological institute the question becomes one of overwhelming urgency, especially when he has no memory of his accident and is aware of disturbing undercurrents in the lives of those surrounding him as later he convalesces at a friend's home.
