Albert's friends keep joking while they wait for breakfast. Beauchamp wants to leave for the Chamber. Debray drinks sherry and complains about politics. Albert says even a great nobleman would wait until half past ten for his guest. They talk about his planned marriage to Eugénie Danglars and laugh about her father's money and speeches.
Château-Renaud arrives with Captain Maximilian Morrel, a soldier in a fine uniform. Château-Renaud tells how Morrel saved his life in Africa. Six Arab horsemen had caught him, and Morrel killed them and shared his horse so they could eat. Morrel quietly adds that he tries to do something brave every year on September 5, the day his father was saved long ago in Marseilles.
Albert then tells his own adventure. In Rome, bandits carried him to the Catacombs of Saint Sebastian and demanded ransom. Franz brought help, but the real rescue came from a stranger with no weapon who spoke two words to Luigi Vampa. Albert describes the Count's grotto, his Greek singer Haydée, and the cold way he watched an execution. His friends refuse to believe any of it. Debray says there are no bandits. Beauchamp says there are no vampires. They call it a fairy tale until the clock strikes half past ten.
The Count walks in exactly on time. No one heard his carriage. He is polite, well dressed, and calm. He eats almost nothing and says he slept in his coach after stopping near Nîmes. He shows an emerald box filled with opium and hashish pills he mixes himself. He mentions Franz's night in the grotto as if it were a small joke. When Albert begs him not to talk about bandits, the Count smiles and tells the whole story anyway.
The table grows stranger. The Count says he helps only people he chooses and does not owe loyalty to society. Morrel asks why he saved Albert then. Albert calls him a secret philanthropist. When the Count names his bankers, Thomson and French, Morrel turns pale. The name links back to his family in Marseilles. The Count already knows Baron Danglars and offers to help Morrel with old debts the bank denies.
Albert's friends argue about where the Count should live. Morrel offers his sister's quiet house. The Count refuses. He says Ali, his mute servant from Rome, has already bought and furnished a house on the Champs-Élysées. He also has theater boxes, a Greek slave who speaks only Romaic, and a steward named Bertuccio who used to be a smuggler. Debray leaves to investigate him with police money. Beauchamp leaves to write an article. Morrel leaves with a calling card and unanswered questions.
At last Albert and the Count are alone. Breakfast is over. The mysterious guest has turned every joke into proof, and Paris is only beginning to learn who he really is.
The breakfast is built as a contest of unbelievable stories, and the Count arrives as the proof. Beauchamp wants the Chamber. Debray times the delay with a watch. Château-Renaud brings Maximilian Morrel and will not let the soldier shrink the African rescue into modesty. Albert then spends his own credit: catacombs, a weaponless stranger, two words to Vampa, a Greek singer, an execution watched without a blink. His friends call it a fairy tale until the guest walks in at half past ten with no carriage anyone heard.
What he eats is almost nothing. What he offers is a box of pills he mixes himself, a joke about Franz's night in the grotto, and the bandit story Albert begged him to skip. He says he helps only the people he chooses. Morrel asks why Albert was chosen. The name Thomson and French turns Morrel pale, because that name once stood between his family and ruin in Marseilles. The Count already knows Danglars, and he offers to touch debts the bank pretends not to see.
The housing argument ends before it starts. Ali has already bought and furnished a house on the Champs-Élysées. Bertuccio, the old smuggler, waited at the Barrière de Fontainebleau with the address on a paper the Count himself had not needed to read. Debray leaves to spend police money on questions. Beauchamp leaves to write. Morrel leaves with a card and the feeling that September the fifth has walked into the room under another face. Albert is left alone with a guest who has turned every joke into evidence.
The house on the paper is the tell. A man who slept in a coach and stopped near Nîmes still has a furnished mansion waiting, a mute servant who hunts addresses like a hound, and a steward who used to run cargo. Paris wanted a character for breakfast. It got a household already installed. The friends who left to investigate will find records, not contradictions. Morrel will find a date. Albert will find that the stranger he rescued into society had chosen the table, the hour, and the witnesses before the sherry was poured.
