Key passages

  • He wanted me, he said, to decide a little wager. Some foolish girl, who had seen De Lancy on the stage, and who believed him the ideal hero of romance, and was only in too much danger of throwing her heart and fortune at his feet, was to be disenchanted by any stratagem that could be devised.

    He asked me to help settle a bet: a naive girl, infatuated with De Lancy after seeing him perform, was at risk of giving him her heart and money, so her family wanted to disillusion her through a trick.

    Mosquetti explains the purpose of the scheme proposed by the mysterious gentleman.

  • Murdered, murdered and innocent! while I, vile dupe, pitiful fool, was only a puppet in the hands of a demon!

    He was killed, and he was innocent! And I was just a foolish pawn controlled by a devil.

    Valerie's anguished outburst upon realizing her husband's role in the deception.

  • I thought, monsieur, that I knew the hideous abyss of your black soul to its lowest depths. I was wrong; I never knew you till tonight.

    I believed I had seen the full extent of your evil nature, but I was mistaken; only now do I truly understand you.

    Valerie confronts her husband, revealing her shock and horror at his past actions.
