Upon reaching London, the Four Musketeers consult Comte de Guercy, the French ambassador to England, for assistance. That evening, Guercy and the Four Musketeers attend a party hosted by Queen Mary Charlotte and King George III, aiming to acquire secret documents held by Robert Wood, the British Undersecretary of Foreign Affairs. During the event, Mary recognizes Lia, prompting Guercy to invite her to a gathering at the French Embassy, while George persuades Wood to join them. Concurrently, Maximilien brings Cagliostro and Lorenza to Medmenham to seek help from Dashwood and Whitehead.
