They found the corridor easily, for it paralleled the river, separated from it only by a single wall. It took them beneath the gardens and the city, always through inky darkness. After they had reached the other side of the gardens, Bradley counted his steps until he had retraced as many as he had taken coming down the stream; but though they had to grope their way along, it was a much more rapid trip than the former. When he thought he was about opposite the point at which he had descended from the Blue Place of Seven Skulls, he sought and found a doorway leading out onto the river; and then, still in the blackest darkness, he lowered himself into the stream and felt up and down upon the opposite side for the little shelf and the ladder. Ten yards from where he had emerged he found them, while the girl waited upon the opposite side. To ascend to the secret panel was the work of but a minute. Here he paused and listened lest a Wieroo might be visiting the prison in search of him or the other inmate; but no sound came from the gloomy interior. Bradley could not but muse upon the joy of the man on the opposite side when he should drop down to him with food and a new hope for escape. Then he opened the panel and looked into the room. The faint light from the grating above revealed the pile of rags in one corner; but the man lay beneath them, he made no response to Bradley's low greeting. The Englishman lowered himself to the floor of the room and approached the rags. Stooping he lifted a corner of them. Yes, there was the man asleep. Bradley shook him--there was no response. He stooped lower and in the dim light examined An-Tak; then he stood up with a sigh. A rat leaped from beneath the coverings and scurried away. "Poor devil!" muttered Bradley. He crossed the room to swing himself to the perch preparatory to quitting the Blue Place of Seven Skulls forever. Beneath the perch he paused. "I'll not give them the satisfaction," he growled. "Let them believe that he escaped." Returning to the pile of rags he gathered the man into his arms. It was difficult work raising him to the high perch and dragging him through the small opening and thus down the ladder; but presently it was done, and Bradley had lowered the body into the river and cast it off. "Good-bye, old top!" he whispered. A moment later he had rejoined the girl and hand in hand they were following the dark corridor upstream toward the farther end of the city. She told him that the Wieroos seldom frequented these lower passages, as the air here was too chill for them; but occasionally they came, and as they could see quite as well by night as by day, they would be sure to discover Bradley and the girl. "If they come close enough," she said, "we can see their eyes shining in the dark--they resemble dull splotches of light. They glow, but do not blaze like the eyes of the tiger or the lion."
