chunk: Faced with the death of his love, Armand betrays Percy, unaware that The Pimpernel has already secured Jeanne's freedom. Sir Percy is then captured and imprisoned by Chauvelin and Heron in the cell that was home to Marie Antoinette in her last days.
  Chauvelin insists that Percy is to be deprived of sleep in the hope that he will be weakened and disclose where young Capet, the uncrowned King of France, is being held following his rescue.
  After 17 days in prison, Percy is sure that the dauphin has been transported safely into Holland. He then contrives, by pretending to crack and confess the dauphin's whereabouts, to make his escape. He tells Chauvelin and Heron that the dauphin is being held in an area in the north, near the coast of France, but that he has to show them, rather than tell them, because the paths are nameless and too small for them to find without him.
