"It's Marvel or some such name. He seems to be known here; he orders people about as if he were at home. The other was Cantelucci, sir." "Very likely. Look here. Spire. I will dine in the public room downstairs. I want to see that angry gentleman. Did you see him, Spire?" "Only his back, sir. Very broad, sir. Tall man. In boots and a riding coat. Are you going down now, sir? The dinner must be on already." "Yes," said Cosmo, preparing to go out. "And by the by. Spire, if you ever see in the street or in that room downstairs, where everyone comes in and out as you say, a long fellow wearing a peculiar cap with a tassel, just try to find out something about him; or at any rate let me know when you have seen him. . . . You could perhaps follow him for a bit and try to see where he goes." After saying those words Cosmo left the room before Spire could make any answer. Spire's astonishment expressed itself by a low exclamation, "Well, I never!" PART II I Cosmo descended into a hall now empty and with most of its lights extinguished. A loud murmur of voices guided him to the door of the dining room. He discovered it to be a long apartment with flat pilasters dividing its whitewashed walls, and resembling somewhat a convent's refectory. The resemblance was accentuated by the two narrow tables occupying its middle. One of them had been appropriated by the British naval officers, had lights on it, and bristled with the necks of wine bottles along its whole length. The talk round it was confused and noisy. The other, shorter, table accommodated two rows of people in sombre garments who at first glance struck Cosmo as natives of the town and belonging to a lower station in life. They had less lights, less wine, and almost no animation. Several smaller tables were ranged against the walls at equal intervals, and Cosmo's eye was caught by one of them because of the candles in the sconce on the wall above it having been lighted. Its cloth was dazzlingly white, and Signor Cantelucci with a napkin in his hand stood respectfully at the elbow of its sole occupant, who was seated with his back to the door. Cosmo was under the impression that his entrance had been unobserved. But before he had walked half the length of the room Signor Cantelucci, whose eyes had never ceased darting here and there while his body preserved its deferential attitude at the elbow of the exclusive client, advanced to meet him with his serious and attentive air. He bowed. Perhaps the signore would not mind sharing the table of his illustrious countryman. "Yes, if my countryman doesn't object," assented Cosmo readily. He was absolutely certain that this must be the doctor of whom Spire had spoken.
