We all three strode down the street in silence, Rupert feverish, myself dazed, Basil, to all appearance, merely dull. We walked through grey street after grey street, turning corners, traversing squares, scarcely meeting anyone, except occasional drunken knots of two or three. In one small street, however, the knots of two or three began abruptly to thicken into knots of five or six and then into great groups and then into a crowd. The crowd was stirring very slightly. But anyone with a knowledge of the eternal populace knows that if the outside rim of a crowd stirs ever so slightly it means that there is madness in the heart and core of the mob. It soon became evident that something really important had happened in the centre of this excitement. We wormed our way to the front, with the cunning which is known only to cockneys, and once there we soon learned the nature of the difficulty. There had been a brawl concerned with some six men, and one of them lay almost dead on the stones of the street. Of the other four, all interesting matters were, as far as we were concerned, swallowed up in one stupendous fact. One of the four survivors of the brutal and perhaps fatal scuffle was the immaculate Lieutenant Keith, his clothes torn to ribbons, his eyes blazing, blood on his knuckles. One other thing, however, pointed at him in a worse manner. A short sword, or very long knife, had been drawn out of his elegant walking-stick, and lay in front of him upon the stones. It did not, however, appear to be bloody. The police had already pushed into the centre with their ponderous omnipotence, and even as they did so, Rupert Grant sprang forward with his incontrollable and intolerable secret. “That is the man, constable,” he shouted, pointing at the battered lieutenant. “He is a suspicious character. He did the murder.” “There's been no murder done, sir,” said the policeman, with his automatic civility. “The poor man's only hurt. I shall only be able to take the names and addresses of the men in the scuffle and have a good eye kept on them.” “Have a good eye kept on that one,” said Rupert, pale to the lips, and pointing to the ragged Keith. “All right, sir,” said the policeman unemotionally, and went the round of the people present, collecting the addresses. When he had completed his task the dusk had fallen and most of the people not immediately connected with the examination had gone away. He still found, however, one eager-faced stranger lingering on the outskirts of the affair. It was Rupert Grant. “Constable,” he said, “I have a very particular reason for asking you a question. Would you mind telling me whether that military fellow who dropped his sword-stick in the row gave you an address or not?” “Yes, sir,” said the policeman, after a reflective pause; “yes, he gave me his address.”
