In Sir William's remote part of Scotland it seems almost possible that a young boy could have been stolen away by the fairies and returned forty years later without having visibly aged. And if the boy isn't Davie Drummond, who is he? Then he suffers a succession of near-fatal "accidents." Could there be a connection with four other local singers who have vanished, one of them with political information of value to Scotland's enemies? Gil Cunningham and his wife Alys have been sent to Perthshire to investigate.
