“Of course. Next to yourself there is no one so sincerely interested as I am. I love Rita as I should have loved a sister if I had had one. Please don’t stand up. Dr. Burton has told you to avoid all exertion for a week or more, I know.” Monte Irvin grasped her outstretched hand. “Any news which reaches me,” he said, “I will communicate immediately. Thank you. In times of trouble we learn to know our real friends.” CHAPTER XXX. THE FIGHT IN THE DARK Towards eleven o’clock at night the fog began slightly to lift. As Kerry crossed the bridge over Limehouse Canal he could vaguely discern the dirty water below, and street lamps showed dimly, surrounded each by a halo of yellow mist. Fog signals were booming on the railway, and from the great docks in the neighborhood mechanical clashings and hammerings were audible. Turning to the right, Kerry walked on for some distance, and then suddenly stepped into the entrance to a narrow cul-de-sac and stood quite still. A conviction had been growing upon him during the past twelve hours that someone was persistently and cleverly dogging his footsteps. He had first detected the presence of this mysterious follower outside the house of Sin Sin Wa, but the density of the fog had made it impossible for him to obtain a glimpse of the man’s face. He was convinced, too, that he had been followed back to Leman Street, and from there to New Scotland Yard. Now, again he became aware of this persistent presence, and hoped at last to confront the spy. Below footsteps, the footsteps of someone proceeding with the utmost caution, came along the pavement. Kerry stood close to the wall of the court, one hand in a pocket of his overall, waiting and chewing. Nearer came the footsteps—and nearer. A shadowy figure appeared only a yard or so away from the watchful Chief Inspector. Thereupon he acted. With one surprising spring he hurled himself upon the unprepared man, grasped him by his coat collar, and shone the light of an electric torch fully into his face. “Hell!” he snapped. “The smart from Spinker’s!” The ray of the torch lighted up the mean, pinched face of Brisley, blanched now by fright, gleamed upon the sharp, hooked nose and into the cunning little brown eyes. Brisley licked his lips. In Kerry’s muscular grip he bore quite a remarkable resemblance to a rat in the jaws of a terrier. “Ho, ho!” continued the Chief Inspector, showing his teeth savagely. “So we let Scotland Yard make the pie, and then we steal all the plums, do we?” He shook the frightened man until Brisley’s broad-brimmed bowler was shaken off, revealing the receding brow and scanty neutral-colored hair.
