Former police detective Michael McLaren arrives in Scotland, ready to immerse himself in the fun of the Highland Games and to enjoy a holiday with Melanie. But the old saying of plans oft going awry rears its ugly head: Simon Shaw, a member of McLaren's folk group, dies. Murdered a year to the day following his uncle's death. McLaren is determined to find out who killed Simon. Needing justice for his friend is only half of his incentive. He also needs to appease his guilt for suggesting the group sing there in the first place. As McLaren becomes immersed in the investigation, he wonders if the two deaths are linked, or have to do with the family or their clan. Perhaps Simon's former wife killed him, bent on revenge more powerful than mere divorce. Or was the killing tied to an old hunt for diamonds? After all, diamonds aren't only a girl's best friend. Sometimes they birth greed and murder. And entrap the innocent.
