This three-part series by historian Lisa Hilton is a follow-up to her previous effort from last July, Charles I: Downfall of a King. That examined his disastrous fall from power, and this first new program opened just before Christmas 1648, with the melancholy monarch incarcerated in Windsor Castle, separated from his wife and children and with only his dogs for company.
