Irving was at battalion headquarters, awaiting orders, which were expected to come after sundown, to move forward into the trenches. While reading the letter he was seated on the log of a tree that had been literally uprooted by a concentrated shell fire at this point a week or two before. Nobody else was interested in what he was doing and he was too much preoccupied to feel much interest in anybody right now except the mysterious Lieut. Tourtelle and his equally mysterious "amputation souvenir."
"Now," continued the boy, resuming his reasoning soliloquy, "if he told me a fake story about being an art student and having one of his fellow students copy one of his pictures on his arm, what was the motive? He wanted to deceive me, of course, but why? I'll have to leave that question unanswered for the present, I'm afraid. If I could get at his real reason for wanting that picture tattooed on his arm, I might feel some encouragement in trying to get at his motive in deceiving me. There's no doubt the picture on his arm is practically the same as the copy on this paper. I shouldn't wonder if they were the same size, drawn with precisely the same dimensions. Supposed to represent a basket of eggs spilling down stairs. What a ridiculous title. I'm sure I'd have hard work picking out the basket and the smashed eggs. It looks to me almost as if someone had pinned this paper up on a wall and fired a lot of eggs at it--and hit it, too, every crack. After all, it's the best title to a cubist art picture I ever heard of. I remember our teacher gave us a talk about that kind of art and showed us some copies of cubist paintings in magazines at the time when everybody was gossiping--yes, that's the word--about cubist art. And we surely had a lot of fun over it.
"Tourtelle told me that another student tattooed that picture on his arm. Bob's description of the scene in the hospital laboratory makes that 'second looie' look very much like a liar. I take it from this letter that both of those men were pretty well advanced in years. Art students as a rule are younger people. Moreover, students wouldn't act so strangely just because they suspected somebody of secretly watching them at their work. Then, again, Bob says the government raided that hospital. What for? Enemy agents, of course; there could be no other reason. And this raid followed Bob's report of his experience to the police. Plain as daylight. And yet, what possible connection can there be between enemy spies and cubist art? I give it up."
Irving would have liked to make a report of some kind concerning the web of strange events that clung in confusing tangle to the mystery of the ridiculous tattooing recently peeled from the amputated arm of Lieut. Tourtelle, but the more he studied over the matter, the more probable it appeared to him that such action on his part would be unwise. His conclusions must of necessity be exceedingly vague. He could not figure out a motive in any way explaining the apparently eccentric ideas and actions of the "hobby ridden second lieutenant." Yes, that phrase characterized Tourtelle exactly when the spy suspicion contained in Bob's letter was dismissed, and undoubtedly the average officer, unless he be of a very suspicious nature, would take that view of it.
"I'd be laughed at if I made a report of this affair without being able to place my finger on anything more definite than I seem to be able to single out now," he concluded. "So I guess I'll have to keep this thing to myself or else whittle my wits to a sharper point than I have been able to whittle them thus far."
About an hour after nightfall Irving returned to the front line trenches together with seventy-five or a hundred other soldiers who constituted a relief shift, to take the place of a like number of tried and muscle-cramped boys whose capacity for efficient service was in need of recuperation. The sector was quiet on this occasion and the relief exchange was effected without notable incident. In fact, conditions were such that it was considered safe to permit most of the soldiers to sleep under ground of sentries here and there along the trenches and in listening posts out in No Man's Land.
But Irving did not "sleep a wink," although general conditions were favorable for sleep in the dugout where he wrapped himself in a blanket and attempted to follow the reposeful example of half a dozen comrades with little on their minds save the ordinary routine of bloody battle in the past and prospect of much more fight and blood in the future. No mystery racked their minds, and they rested peacefully enough. With Private Ellis, however, it was different, and in a very few minutes after he lay down a plausible solution of the puzzle that had been teasing him for several hours popped into his brain with startling suddenness and rendered sleep about as impossible to him as peaceful surrender was to outraged Belgium.
After the excitement of the first thrill was over, Irving was unable to trace the process by which he arrived at his conclusion. After all, "process" is too slow a word to use in this relation. "The first thing he knew," his mind had jumped from the rough pen sketch of the cubist art drawing in his pocket to the tattooed copy as he had seen it on Tourtelle's arm. A moment later he found himself almost weirdly interested in the recollection of a marked difference in these two copies which had not impressed him before.
Then came a new thrill of eagerness, followed by incredulity, then eagerness and incredulity battling for supremacy, over a suspicion that would not be downed in spite of its almost laughable character. Could it be possible? Yes, no, yes, no--back and forth the contradictions swung. But one thing was certain; Irving recalled it distinctly: In the maze of configurations of "distorted cubes" were myriads of dots and dashes, dots and dashes. What could they mean? If the theory which forced itself upon him was correct there was only one reasonable solution of the whole mystery.
The boy in the dugout could scarcely contain his excitement as the seemingly logical explanation of the mystery "dotted and dashed" itself into a position of settled conviction in his mind.
