He sat brooding for a while, possessed by the girl's image. Then he revolved in his mind all that curious, stirring and tragic adventure, in which he had been so very near succumbing; and, taking a hand-glass from the table, he gazed for a long time and with a certain self-complacency at his features, which illness and pain had not succeeded in impairing to any great extent: "Good looks count for something, after all!" he muttered. V THE RED SILK SCARF On leaving his house one morning, at his usual early hour for going to the Law Courts, Chief-inspector Ganimard noticed the curious behaviour of an individual who was walking along the Rue Pergolese in front of him. Shabbily dressed and wearing a straw hat, though the day was the first of December, the man stooped at every thirty or forty yards to fasten his boot-lace, or pick up his stick, or for some other reason. And, each time, he took a little piece of orange-peel from his pocket and laid it stealthily on the kerb of the pavement. It was probably a mere display of eccentricity, a childish amusement to which no one else would have paid attention; but Ganimard was one of those shrewd observers who are indifferent to nothing that strikes their eyes and who are never satisfied until they know the secret cause of things. He therefore began to follow the man. Now, at the moment when the fellow was turning to the right, into the Avenue de la Grande-Armee, the inspector caught him exchanging signals with a boy of twelve or thirteen, who was walking along the houses on the left-hand side. Twenty yards farther, the man stooped and turned up the bottom of his trousers legs. A bit of orange-peel marked the place. At the same moment, the boy stopped and, with a piece of chalk, drew a white cross, surrounded by a circle, on the wall of the house next to him. The two continued on their way. A minute later, a fresh halt. The strange individual picked up a pin and dropped a piece of orange-peel; and the boy at once made a second cross on the wall and again drew a white circle round it. "By Jove!" thought the chief-inspector, with a grunt of satisfaction. "This is rather promising.... What on earth can those two merchants be plotting?" The two "merchants" went down the Avenue Friedland and the Rue du Faubourg-Saint-Honore, but nothing occurred that was worthy of special mention. The double performance was repeated at almost regular intervals and, so to speak, mechanically. Nevertheless, it was obvious, on the one hand, that the man with the orange-peel did not do his part of the business until after he had picked out with a glance the house that was to be marked and, on the other hand, that the boy did not mark that particular house until after he had observed his companion's signal. It was certain, therefore, that there was an agreement between the two; and the proceedings presented no small interest in the chief-inspector's eyes.
