chunk: Adet's plans suffer a setback when he discovers that Yvonne was warned by Sir Percy and that she is at risk from Martin-Roget. Yvonne has eloped with Lord Antony Dewhurst.
  The Duc believes that Martin-Roget is a millionaire banker whose marriage to Yvonne will result in substantial funds being given to the French royalist cause. He is furious that his plans have been thwarted and refuses to recognise the marriage to Dewhurst, which would not be legal in France due to Yvonne's age. Martin-Roget convinces the Duc that he still wishes to marry Yvonne and soon persuade him to lure Yvonne away from Lord Tony. He then kidnaps her and the three set off for France.
  Lord Tony must seek the help of The Scarlet Pimpernel to save his wife.
