CHAPTER XI
IRVING TELLS THE SERGEANT
"Dots and dashes, dots and dashes, dots and dashes," kept running through Irving's mind.
He took Bob's letter from his pocket and drew from the envelope the paper containing his cousin's copy of "The Basket of Eggs Spilling Down Stairs."
"Bob drew this in a hurry, or at least he had no appreciation of the value of minute details which, I believe, are more important than a thousand baskets of eggs," the young soldier mused as he gazed at the cleverly drawn, but rather inaccurate, copy in the light of the trench lamp. "He disregarded most of those clots and dashes, except in a few places, thinking, I suppose, that continuous lines would do just as well. And he was right so far as the picture is concerned. In fact, I believe those dots and dashes that were on Tourtelle's arm detracted from the art of the artist, if I may pose as an art critic; but for the purpose intended they are absolutely essential.
"Now, I wish I could get hold of an officer who would listen to me and maybe I could start an investigation that would result in something worth while. But Sergt. Wilson, who messes in here, is out with some other men in a listening post and I'm sure it would be better to approach the lieutenant through him. That means I've got to wait here probably until morning before I can get this great weight of responsibility off my mind."
And that was exactly what he did. He lay there thinking over and over again the events of his own and his cousin's adventures concerning Lieut. Tourtelle. There was no use of his attempting to slumber, and it was not long before he gave up the idea entirely. However, he was in no great need of sleep, inasmuch as he had almost reveled in the luxury of rest ever since he was ordered to the field hospital for treatment of his shoulder.
Through all the rest of the night, Irving continued to review and analyze the strange case of "freak art." And perhaps it was fortunate that he had ample opportunity to do this, for it is quite possible that otherwise he would not have had certain important points sufficiently in mind to make a strong and convincing case when at last he found opportunity to make his report.
"It seems to me those dots and dashes explain Tourtelle's anxiety to keep that tattooing on his arm," the boy mused. "Now, if he's a spy, he was putting over just a clever 'con game' when he sent for me and begged my forgiveness and then asked me to do him a favor. After all, I've got to admit that that fellow is pretty smooth. No, I don't think he overdid it at all. I did think it a little strange when he followed his plea for forgiveness with a request that I do him a favor. But the favor was so simple, although unusual enough, goodness knows, and there appeared to be so little opportunity for him to trick me into something I wouldn't like to do, that it seemed foolish for me to hesitate. It looks now as if he tricked not only me, but the surgeon and nurses, too. I wonder what that surgeon would say if he knew that a spy had made clever use of him to prevent a very deep enemy plot from going to pieces at a time when the bottom was about to drop out of it. He'd be a lot sorer, I bet, than he was when I contradicted him after he said Tourtelle's mind was wandering under the anæsthetic.
"'A Basket of Eggs Spilling Down Stairs'--that's some name for a painting. I wonder what's behind it. Now, it's just possible that that name's written somewhere in cipher in the picture, and maybe a key goes with it and that key applied to the name will produce the message he's carrying to the enemy. I suppose he'll watch his opportunity and--
