There followed a wait of rather nervous expectancy for Irving. It really was not more than half an hour, although it seemed much longer to the young soldier who made the original complaint. At last, however, came a ring of the muffled telephone bell, and Lieut. Osborne lifted the receiver to his ear. He listened a minute or two, then hung up the receiver and said:
"Ellis, you and I are ordered to proceed to the hospital and confront this young spy of yours with the fact that we have the goods on him. The captain communicated with the major, and the major with the colonel; so, you see, your story has gone up to the head of the regiment. Sergt. Wilson, I am going to leave you here in my place while I'm gone. I hope to be back before nightfall. If I'm delayed longer than I expect to be, I'll communicate with you by 'phone. Ellis, we'll start at once. The colonel has ordered an automobile to be ready to meet us at the nearest relief station back of the lines. Come on."
In a few minutes the officer and the private were racing through the nearest communication trench, which was deep, sinuous and well camouflaged, on past the second and third lines to the relief station just beyond a small inn covered with a growth of trees and a thicket of tall bushes. The promised automobile was waiting for them, and they were soon speeding away toward the field hospital which, in the last hour, as a result of Private Ellis's story, had become a center of very serious interest in a strange admixture of an elaborate spy system and "high art."
Lieut. Osborne and his companion were both apprehensive lest they find the second lieutenant in condition so weakened that it would be inadvisable to subject him to the strain of a "third degree." They discussed this possibility on the way, and the officer decided that he would broach the subject gently in order to avoid the danger of defeating their purpose through a physical and mental collapse of the patient.
But Lieut. Tourtelle proved to have withstood the shock of the operation much better than might have been expected. They found him looking really bright and vigorous. Apparently he had had the best of care and had rested well. Nevertheless, Lieut. Osborne called a nurse aside and asked her to administer a stimulant to him, as he had important business with the patient under instructions from the commander of the regiment. The nurse did as requested without arousing any suspicion in the "cubist art spy."
"This is quite a surprise to receive a visit from a superior officer under such circumstances, and I'm sure it's very much appreciated," Tourtelle remarked after he had answered several questions put by Lieut. Osborne regarding his condition and the attention he was receiving.
"The occasion fully warrants our coming to see you," the superior officer replied in a purposely peculiar tone of voice. Tourtelle noticed it and looked inquiringly at Lieut. Osborne.
"Private Ellis told me about that art souvenir that was peeled off your arm and I have come to see it," continued the leader of the "visiting expedition."
Tourtelle shot a furtive, searching glance at each of his callers. These glances did not escape the observation of either the officer or the private, for both were looking for evidence of this sort; but they were well on their guard and did not betray, by the slightest expression, any evidence of what was going on in their minds.
"Of course you have it here," Lieut. Osborne continued in tone of assurance. "Ellis tells me he laid it by the side of your pillow and asked the nurse to call your attention to it after you came out from the effects of the anæsthetic."
