The previous evening, on returning from a delicate mission, Saint-Lucq had learned both that the Blades had resumed service and that he would be rejoining them under the direct command of La Fargue. The captain, however, had wished to keep the half-blood in reserve and it was agreed that he would await his orders at the Gaget Messenger Service. This idea had not displeased him. It indicated that the captain wished to keep a card up his sleeve, and that he was to be this card. But to be played against whom, and to what end? Did La Fargue mistrust someone within the Palais-Cardinal, or even among the Blades themselves? Saint-Lucq had not deemed it necessary to ask the question. Nevertheless, there was something fishy going on and Agnes de Vaudreuil, evidently, had not taken long to come to the same conclusion. Hence the appearance of Ballardieu on the half-blood's heels.
With La Fargue's letter in his pocket, thanks to Nai's, Saint-Lucq proceeded at a steady, tranquil pace as far as the quays along the Seine, which he then followed upstream. Then, by way of the Pont Neuf and the elegant Place Dauphine, he arrived at the Palais de la Cite. He had concluded that he needed to shake Ballardieu from his tail without seeming to do it on purpose, in order not to arouse his suspicions and, above all, those of Agnes, who seemed to be dancing a strange pas de deux with La Fargue. The half-blood's loyalty was to his captain first, and the Palais de la Cite was ideally suited for
an impromptu game of hide-and-seek. At one time the seat of royal power, it was now, among other things, the most important court of law in the French kingdom, housing fourteen of the twenty-nine jurisdictions in Paris within a jumble of buildings dating back to the Middle Ages.
Saint-Lucq entered via rue de la Barillerie, and then through a gate flanked by two turrets. Beyond were two courtyards to either side of the Sainte-Chapelle. The courtyard on the left was that of the Chamber of Accounts: full of horses, carriages, and shops spilling over from the neighbouring streets, its walls were hung with signboards displaying the names and portraits of criminals at large. The Mai courtyard lay to the right, giving access to a staircase and then a gallery leading to the Salle des Pas Perdus. This immense, high-ceilinged, dusty, and noisy waiting room had been rebuilt in stone after a fire in 1618. It was swarming with people—lawyers, prosecutors, and clients who chattered and argued, often shouting and sometimes even coming to blows in a heated atmosphere aggravated by all the legal chicanery. But the plaintiffs and the men of law in their long black robes were not the only individuals haunting the place. It was also invaded by a multitude of curious onlookers and customers of the two hundred and twenty-four shops which occupied the galleries and passageways within the Palais. All sorts of trifles were sold in these small shops whose keepers called out to potential buyers: silks, velvets, lace, bibelots, jewellery, fans, precious stones, hats, gloves, cravats, books, and paintings. They were favoured as meeting places; elegant ladies strolled here, and handsome messieurs gave the glad eye to all of them.
Saint-Lucq had little trouble losing Ballardieu in this populous maze. After wandering about in an apparently innocent fashion, he suddenly found a hiding place and watched from afar as the old soldier hurried straight on. The half-blood quickly left the Palais, feeling quite pleased with himself.
He was then free to return to the mission which La Fargue had entrusted to him. He crossed the Seine by the Petit Pont and went to rue de la Fontaine in the faubourg Saint-Victor. There he found a house that he was supposed to first search and then keep an eye on. It was the dwelling of a young woman— a certain Cecile Grimaux—whom the Blades were protecting after some hired swordsmen had tried ro abduct her the previous night. Marciac had foiled their attempt, proof that the years had not changed him in the least and that he was still as gifted as ever at playing the valiant knight rescuing demoiselles in distress. Whatever anyone thought of this, such occasions were rare and when they did present themselves, they always seemed to favour the Gascon.
The house was small, modest, and discreet; on the side facing the street, only the shutters and windows distinguished it from its neighbours on this weekday morning. After a quick and unobtrusive look at the place, Saint-Lucq went around to the rear, into the garden, and found a window that had already been broken into and left open. He entered cautiously, subjected the ground floor to a rigorous examination, found signs of a fight—or at least a violent upheaval—in the stairway, continued up to the next floor, and noted a certain disorder and the wide-open window through which Marciac and his protegee had no doubt made their escape to the rooftops.
