For a hundred yards or more I was obliged to trot, till I saw another cab drop its fare just ahead, and managed to secure it and give the cabman instructions to follow the cab in front, before it turned a corner. The chase was difficult, for the horse that drew me was a poor one, and half a dozen times I thought I had lost sight of the other cab altogether; but my cabman was better than his animal, and from his high perch he kept the chase in view, turning corners and picking out the cab ahead among a dozen others with surprising certainty. We went across Charing Cross Road by way of Cranborne Street, past Leicester Square, through Coventry Street and up the Quadrant and Regent Street. At Oxford Circus the Jew's cab led us to the left, and along Oxford Street we chased it past Bond Street end. Suddenly my cab pulled up with a jerk, and the driver spoke through the trapdoor. "That fare's getting down, sir," he said, "at the corner o' Duke Street." I thrust a half-crown up through the hole and sprang out. "'E's crossing the road, sir," the cabman finally reported, and I hurried across the street accordingly. The man I was watching was strikingly Jewish enough, and easy to distinguish in a crowd. I had almost overtaken him before he had gone a dozen yards up the northern end of Duke Street. He walked on into Manchester Square. There a small, neat brougham, with blinds drawn, was being driven slowly round the central garden. I saw Samuel walk hurriedly up to this brougham, which stopped as he approached. He stepped quickly into the carriage and shut the door behind him. The brougham resumed its slow progress, and I loitered, keeping it in view, though the blinds were drawn so close that it was impossible to guess who might be Samuel's companion, if he had one. I think I have said that when the Jew came to the office door with Hewitt I perceived that he was a man I had seen before that day. I was now convinced that I had also seen that same brougham, at the same time; but of this presently. The carriage made one slow circuit, and then Samuel got out and shut the door quickly again. I took the precaution of turning my back and letting him overtake and pass me on his way back through Duke Street. At the end of the street he mounted an omnibus going east, and I took another seat in the same vehicle. The rest was uninteresting. He went direct to No. 150 Hatton Garden, and there remained. I read his name on the door-post among a score of others, and after a twenty-minutes' wait I returned to my rooms. I had no doubt that it was the meeting in the brougham that Hewitt wished reported, and I remembered his rule was never to watch a man a moment after the main object was secured. Hewitt was out, and he did not return till after dusk. Then he came straightway to my rooms.
