Smythewood Estates in Medonte Township, Ontario, is the setting for The King’s Puzzle. Sixteen-year-old Angus Wolfe wants to know why in 1939 a ten-year-old boy named Duncan, his grandfather, failed to keep a rendezvous with The King at Carley station. The mystery involves the “King’s Puzzle”, a treasure hunt which Duncan created especially for His Majesty King George VI to solve while touring Canada in 1939. A handwritten note, which the King left for Duncan with a Colonel Smythe, would be a promising lead, if Angus could locate it.
In attempting to solve the Puzzle, Angus and his girlfriend Amanda endanger their lives. Who wants the Puzzle to remain unsolved? A Buckingham Palace publicist and his prodigal daughter? The Smythe family, which guards the truth about an unsolved 1939 disappearance of a family member? Blackmailers who surround the Smythe family?
Amanda’s affections for Angus are put to the test when he falls under the spell of the alluring 38-year-old Sharol Smythe, whose husband is the grandson of Colonel Smythe. What started as a family mystery enlarges to at least four mysteries, including a case that the police closed decades earlier.
