Dogtanian's Trance. Dogtanian, Planchet and Sandy are still searching for Juliet. On the run from the Cardinal's Guards, she meets Planchet and begs him to lend her Sandy. She returns the horse but promptly disappears again. Meanwhile Richelieu, incensed by his subordinates' failures, turns to Milady in a bid to prevent the meeting between the Queen and the Duke of Buckingham. Milady lures Dogtanian to her house, where she drugs him and orders him to kill the Queen. Having disposed of the guards, Dogtanian enters the Queen's bedroom as Juliette is telling her of her failed mission. The Queen foils the attempt on her life, knocking Dogtanian unconscious. When he comes round he is himself again. Juliette helps him escape just as the King and the Cardinal burst in and take him to safety through a secret passage, but is angry with him for being so easily seduced by a beautiful lady. She confesses her love for Dogtanian, which leaves him jumping for joy.
