They separated, and Lawless proceeded along the starboard alleyway, glancing into each cabin to make sure that it was unoccupied. Everywhere there were signs of hurry and disorder, showing that the passengers had only had sufficient time to collect a few necessary articles before taking to the boats. All the starboard cabins proved to be empty, and, having reached the end of the alleyway, the Lieutenant crossed to the other side, where he expected to meet Cassidy. The latter was nowhere to be seen, however, and it was not till Lawless had made his presence known by a shout that he heard the mechanic's voice.
"Mr. Lawless, sorr, come quick! I've——"
The rest was drowned in a deafening crash, and the Lieutenant stepped back only just in time to escape being buried beneath tons of burning wreckage which had suddenly descended into the alleyway, followed by one of the huge iron girders that supported the deck above. He was thus cut off by a wall of blazing débris unless the starboard alleyway, through which he had just passed, was still open. Realising that there was not a moment to be lost, he dashed back, only to find his way barred by a portion of the engine-room bulkhead which had collapsed right across the passage.
Rushing back to the port alleyway, he was again stopped by the flaming barrier which lay across it. At first sight it seemed utterly impossible to get past it, but after a moment Lawless noticed a small, tunnel-like cavity beneath the wreckage where it was held up by the fallen girder, one end of which rested on the framework of the deck above. If he could only crawl through that and right underneath the smouldering furnace he might succeed in reaching the other side. So, dropping on all fours, he started to crawl into the opening, well aware that at any moment the girder might wholly collapse and crush him beneath its weight. If that happened he would be either mercifully killed outright or else pinned down and slowly roasted to death.
Almost suffocated by the smoke, he succeeded in forcing his way through and at last emerged safely on the other side. For a moment or two he was blinded by the smoke and could see nothing, but as he staggered to his feet a hand clutched his arm.
"Be the powers, 'tis yerself, sorr, the saints be praised!" cried the voice of Cassidy. "Are ye hurt, now?"
"No, no; but have you found anyone?"
"Shure I have that. There's a poor divil pinned down in his bunk yonder, and, though I've thried wid all me moight, I can't raise him."
"Then I'll lend you a hand, Mike. There's no time to lose, for this packet's settling fast," replied Lawless.
Cassidy led the way into one of the cabins, where a man lay in the lower berth, held down by the upper one, which had collapsed and fallen upon him. He was unconscious, evidently having been stunned by the falling mass. Between them they managed to remove enough of the wreckage to admit of his being dragged out of the berth. As they carried him from the cabin there came a thunderous crash, and Lawless saw the end of the great girder under which he had crawled give way and bring down with it the burning mass it had supported. Now, both fore and aft, they were imprisoned by a wall of flaming wreckage that made escape seem hopeless.
