The Scarlet Pimpernel

The Chauvelin discovered letter, one signed by Armand, which seemingly incriminates him. The Chauvelin plans to use the information to get Marguerite to help discover the Pimpernel's identity.

He opened one or two letters from Sir Andrew Ffoulkes’ pocket-book, noted the tiny scrap of paper which the two young men had only just had time to read; but one letter specially, signed Armand St. Just, seemed to give him strange satisfaction.
“Armand St. Just a traitor after all,” he murmured. “Now, fair Marguerite Blakeney,” he added viciously between his clenched teeth, “I think that you will help me to find the Scarlet Pimpernel.”
