"Not unless the fellow who was seized out in the hall and dragged into the laboratory should appear suddenly and contradict your statement," the investigating officer answered. "By the way, did you know the hospital was raided by government agents a few days after the tattooing operation?"

By this time, Tourtelle, who must have realized the gravity of the situation, had summoned all the nerve needed to provide him with a bold front to meet the emergency. He just sat and stared blankly at his visitors.

"Why don't you answer?" Lieut. Osborne demanded.

"Because I haven't the faintest idea what you're driving at," Tourtelle replied, with well assumed mystification. "But I'm sure of one thing, or rather one of two things, and that is that either somebody has put you on a very bum steer, or you have got things very badly twisted.

"By surrendering to our enemy at the first opportunity," was the answer. "That's what you tried to do out in No Man's Land the night you were wounded."

This was a new startler for the wounded spy, as was evident from the expression on his countenance. After a few moments of undoubtedly painful meditation, he continued:
