The Death of the Spy
The inability of Lieutenant Mackinson to add a single word of further information to what he had said as he regained consciousness on the promenade deck increased the mystery.
The young lieutenant, it seemed, had been following a trail which he believed was leading him closer and closer to the object of the hunt, and it was in forging the links of this chain of circumstantial evidence that the young officer was led into the lower depths of the ship.
"From a sailor who did not know why I was inquiring," he told the captain, "I learned that on the night the unknown man invaded the battery room this sailor had seen another member of the crew, presumably from the engine or boiler room, throw aside something as he hurried along the passageway leading from the wireless room. He was in his undershirt.
"The sailor said he was about to investigate when he saw us come along, and you stooped to pick up whatever it was that had been thrown away.
"While I was talking to him another member of the crew, evidently also from the boiler or engine room, brushed by us. He had disappeared when the sailor said to me, 'I think that was the fellow—the one that just went by.' Not wanting to arouse his suspicions, I ended the conversation with a casual remark, and then strolled away until I was out of the sailor's sight, and then hurried as fast as I could toward the engine room.
"I do not know that part of the ship well, and it was very dark down there. I was groping my way along when I thought I heard steps just ahead of me. I stopped to listen, and when the sound was not repeated I proceeded onward.
"All of a sudden I was grasped by the neck and one arm from behind, and thrown into that closet. Before I could utter a word I was a prisoner behind a locked door. I called several times, and, receiving no response, realized that I must be some distance from anyone else and that the noises of the engines completely drowned out my voice.
"Every moment it became more stifling in there, and I had no doubt that I had walked directly into a death-trap. It was then I began signaling on the steam-pipe. I guess it was a mighty lucky thing for me that Slim Goodwin strolled out on deck just at the time he did."
And that was all that Lieutenant Mackinson could tell. The mysterious stranger remained what he had been from the first—a desperate and dangerous and unknown spy, lurking somewhere upon the American transport Everett with the evident intention of making the ship's position known to German U-boats when the Everett and her convoy of cruisers and destroyers entered the danger zone.
