Monsieur de Vargnes knew the lady very well, who was a very agreeable Creole from Haiti, and whom he had met in many drawing-rooms, and, on the other hand, though the doctor's name did not awaken any recollections in him, his quality and titles alone required that he should grant him an interview, however short it might be. Therefore, although he was in a hurry to get out, Monsieur de Vargnes told the footman to show in his early visitor, but to tell him beforehand that his master was much pressed for time, as he had to go to the Law Courts. When the doctor came in, in spite of his usual imperturbability, he could not restrain a movement of surprise, for the doctor presented that strange anomaly of being a negro of the purest, blackest type, with the eyes of a white man, of a man from the North, pale, cold, clear, blue eyes, and his surprise increased when, after a few words of excuse for his untimely visit, he added, with an enigmatical smile: "My eyes surprise you, do they not? I was sure that they would, and, to tell you the truth, I came here in order that you might look at them well, and never forget them." His smile, and his words, even more than his smile, seemed to be those of a madman. He spoke very softly, with that childish, lisping voice, which is peculiar to negroes, and his mysterious, almost menacing words, consequently, sounded all the more as if they were uttered at random by a man bereft of his reason. But his looks, the looks of those pale, cold, clear, blue eyes, were certainly not those of a madman. They clearly expressed menace, yes, menace, as well as irony, and, above all, implacable ferocity, and their glance was like a flash of lightning, which one could never forget. "I have seen," Monsieur de Vargnes used to say, when speaking about it, "the looks of many murderers, but in none of them have I ever observed such a depth of crime, and of impudent security in crime." And this impression was so strong, that Monsieur de Vargnes thought that he was the sport of some hallucination, especially as when he spoke about his eyes, the doctor continued with a smile, and in his most childish accents: "Of course, Monsieur, you cannot understand what I am saying to you, and I must beg your pardon for it. To-morrow, you will receive a letter which will explain it at all to you, but, first all, it was necessary that I should let you have a good, a careful look at my eyes, my eyes which are myself, my only and true self, as you will see." With these words, and with a polite bow, the doctor went out, leaving Monsieur de Vargnes extremely surprised, and a prey to this doubt, as he said to himself: "Is he merely a madman? The fierce expression, and the criminal depths of his looks are perhaps caused merely by the extraordinary contrast between his fierce looks and his pale eyes." And absorbed in these thoughts, Monsieur de Vargnes unfortunately allowed several minutes to elapse, and then he thought to himself suddenly:
