Since infancy, Michael McLaren has been the target of his paternal grandfather’s anger. So, when the patriarch sends an invitation to heal the rift, McLaren travels to Scotland, eager to meet and finally end the feud. But the welcome never happens. If grandfather hadn’t invited him, who had? And why?
In Edinburgh, a man standing beside McLaren in a bus queue is killed in a hit-and-run accident. After an attack leaves McLaren for dead on a wintry moor, he’s convinced someone from his past is trying to murder him.
As McLaren trails the hit-and-run driver from the medieval "underground city" of Edinburgh to the Boar’s Rock, the MacLaren Clan’s ancestral meeting place, the assaults intensify, and he’s plunged into a very personal hunt for a World War II treasure. The puzzle is fascinating; he just has to stay alive to solve it.
