“Yes! I heard him. I went and looked in! He was asleep! It wasn’t Allen that we saw!”

“For Heaven’s sake!” gasped Bull. “What do you mean?”

“I tell you that it wasn’t Allen! What are you gaping at me that way for? Allen hasn’t been out of his tent. The sentry told me so!”

Bull and Gus Murray were thunderstruck. If the world had been coming to an end just then they couldn’t have been more confounded.

“Not out of his tent!” they gasped. “Then, in Heaven’s name! who did we see?”

“I don’t know; but it wasn’t Allen.”

“But he had his uniform, man! And none of the other tacs have come up from the Point yet! He’s the only one here; it must have been Allen!”

He leaped up with a furious imprecation.
