The doctor, the subject of this imprecatory monologue, had concealed the disquietude he felt by the discovery he had just made. He knew Abbé Ledoux capable of taking a brilliant revenge, so as he descended the steps of the saintly man's house, the doctor, before entering his carriage, looked cautiously on both sides of the street. As he expected, he saw a public cab about twenty steps from where he was standing. In this cab was a large man, wearing a brown overcoat. Walking up to the cab, the doctor, with a confidential air, said in a low voice to the large man: "My friend, you are posted there, are you not, to follow this open carriage with two horses, standing before the door, Number 17?" "Sir," said the man, hesitating, "I do not know who you are, or why you--" "Hush! my friend," replied the doctor, in a tone full of mystery, "I have just left Abbé Ledoux; the order of proceeding is changed; the abbé expects you at once, to give you new orders,--quick, go, go!" The fat man, reassured by the explicit directions given by the doctor, hesitated no longer, descended from his cab, and went in haste to see the Abbé Ledoux. When the doctor saw the door close upon the emissary of the abbé, feeling certain that he was not followed, he ordered his coachman to drive in haste to the Faubourg Poissonnière, for if he feared nothing for his nephew, he had reason enough for uneasiness since he had learned that Abbé Ledoux was concerned in this intrigue. The doctor's carriage had just entered one of the less frequented streets of the Faubourg Poissonnière, not far from the gate of the same name, when he perceived at a short distance quite a large assemblage in front of a modest-looking house. The doctor ordered his carriage to stop, descended from it, mingled with the crowd, and said to one of the men: "What is the matter there, sir?" "It seems, sir, they are taking back a stray dove to the dove-cote." "A dove!" "Yes, or if you like it better, a young girl who escaped from a convent. The commissary of police arrived with his deputies, and a very fat man in a blue overcoat, who looked like a priest. He had the house opened. The fugitive was found there, and put into a carriage with the fat man in a blue overcoat. I have never seen any citizen ornamented with such a stomach." Doctor Gasterini did not wait to hear more, but rushed through the crowd and imperatively rang the bell at the door of the little house of which we have spoken. A young servant, still pale with emotion, came to open it. "Where is Madame Dupont?" asked the physician, impatiently. "She is at home, sir. Oh, sir, if you only knew!" The doctor made no reply; went through two apartments, and entered a bedchamber, where he found an aged woman, with a venerable-looking face full of sweetness. "Ah, doctor, doctor!" cried Madame Dupont, bursting into tears, "what a misfortune, what a scandal, poor young girl!"
