The infallible passage of the king at the same hour was hence the daily event of the Boulevard de l'Hôpital. The promenader in the yellow coat plainly did not belong to that quarter, and probably not to Paris, for he was ignorant of the fact. When at two o'clock the royal carriage, surrounded by Life Guards with their silver aiguillettes, turned into the boulevard, after coming round the Salpêtrière, he seemed surprised and almost terrified. As he was alone in the walk, he quickly concealed himself behind an angle of the wall; but this did not prevent the Duc d'Havre from noticing him. As Captain of the Guards on duty that day, he was seated in the carriage opposite to the king, and said to his Majesty,--"There is an ill-looking fellow." The policemen, who cleared the way for the king, also noticed him, and one of them received orders to follow him. But the man turned into the solitary streets of the Faubourg, and, as night was setting in, the agent lost his trail, as is proved by a report addressed the same evening to Count Anglès, Minister of State and Prefect of Police. When the man in the yellow coat had thrown out the agent, he doubled his pace, though not without looking back many times to make sure that he was not followed. At a quarter-past four, that is to say, at nightfall, he passed in front of the Porte St. Martin theatre, where the "Two Convicts" would be performed that evening. This bill, lit up by theatre lamps, struck him, for though he was walking rapidly, he stopped to read it. A moment later he entered "The Pewter Platter," which was at that time the office of the Lagny coach, which started at half-past four. The horses were put in, and the passengers, summoned by the driver, were hastily clambering up the iron steps of the vehicle. The man asked,-- "Have you a seat left?" "Only one, by my side, on the box," the driver said. "I will take it." "Get up," the driver said. Before starting, however, he took a glance at the passenger's poor dress and the smallness of his bundle, and asked for the fare. "Are you going all the way to Lagny?" he said. "Yes," the man answered. The traveller paid his fare to Lagny and the coach started. After passing the city gate, the driver tried to get up a conversation, but the traveller only answered in monosyllables; so the driver began whistling and swearing at his horses. As the night was cold, he wrapped himself in his cloak, but the passenger did not seem to notice it. At about six o'clock they reached Chelles, where the driver stopped for a moment to let his horses breathe, at an inn opened in the old buildings of the Royal Abbey. "I shall get down here," the man said. He took his bundle and stick and jumped off the coach. A moment after he had disappeared, but he did not enter the inn. When the coachman started again a few moments after, he did not meet him in the high street of Lagny, and he turned round to his inside passengers:--
