door leading, as Bob conjectured, to the kitchen? In that case they would certainly discover him. He could not risk discovery, so tiptoeing along the corridor he followed the men, calculating his pace by the sound of their shuffling footsteps ahead. He came in a few moments to the foot of the staircase, and knew by the hollow sounds coming down that the three men had ascended. Their mission apparently was either to the roof or to the heavily-barred door he had passed on his descent. The passage led on past the opening of the staircase, and as it was quite dark in that direction Bob resolved to go on for a few steps and await the men’s return, trusting to the darkness to conceal him. Listening near the foot of the stairs he heard the clatter of the bolts as they were withdrawn at the door above, then the creak of rusty hinges. There was an interval; then he heard the men returning, and as they came down, with the sound of their voices was mingled the clank of chains. They descended slowly, and as with care. They reached the bottom; they entered the passage; and then in the dim glow Bob saw that there were not three men now, but four. The fourth, a smaller man than the rest, was being half pushed, half dragged along, and all the time his every movement was accompanied by the clank-clank of metal. Bob felt a rush of blood to his face; his fingers tingled as though with galvanism. He pressed on after the group. They came, as he had done, to the great iron door. As he had done, they turned into the corridor opposite; and they passed into Chang-Wo’s hall by the draped door where Bob himself had but a few minutes before been peeping. Almost reckless of consequences he followed them. They left the door half open, and from the folds of a silken hanging he beheld a piteous scene. Between two of the Manchu guards Kobo was held up before his enemy. He was but the shadow of his former self. Bob could not see his face, but he saw his thin manacled wrists, he saw the hollows in his neck, and these, with the drooping helplessness of his attitude, were evidence of something too terrible for words. Chang-Wo was speaking. He took the pipe from his mouth and jerked a word at the third Manchu, who went into the kitchen and returned with a metal can. Then Chang-Wo spoke to Kobo, snapping out the syllables in a harsh staccato that matched well the cold cruelty of his stony face. It mattered little to Bob that he could not understand what the Manchu said, or what Kobo replied in a thin husky whisper, scarcely audible. He heard a mocking note in Chang-Wo’s voice; he saw the cup held before Kobo’s face, but just beyond his reach; he saw Kobo’s head move slowly from side to side as if making the gesture of refusal; and he guessed that this was the extremity of torture to which his friend had been put: that he had been kept without water, and that a brimming cup was now being offered to him in the hope of tempting him to betray his country.
