“Unless I’m greatly mistaken, it’s our friend the captain,” he added.

“Sure it is, and no mistake,” chuckled Bud; while Blake drew in a long breath that spelled relief because his “watchful waiting” period was over.

As the officer approached they took new hope upon seeing the look spread upon his face. Surely he would not smile so broadly if he were bringing them bad news.

“It’s all right, boys, all right,” he told them, immediately.

“Then the general has given permission for us to carry out the scheme, has he, sir?” asked Hugh, greatly pleased.

“He told me to take charge of it personally, and leave no stone unturned to ascertain how Private Gregory could be taken out of the camp undetected; also to bring before him those guilty of the outrage, if they could be caught. That house, it seems, comes within the boundaries of the camp, and hence any one living there, or occupying the premises, is amenable to military discipline and rules.”

“Then if by good luck we trap that schemer and good-for-nothing Luther Gregory,” exclaimed Blake, rubbing his hands in joy, “it’s going to be hard for him because he’s interfered with the liberty of one of Uncle Sam’s recruits? Well, I guess on the whole he’ll get only what he deserves, and I’ll be glad of it.”

“Are you going with us, Captain?” asked Bud.

“Yes, and I shall take a detail of men, so as to make doubly sure,” explained the officer, as though he had mapped out his plan of campaign, like a wise soldier, as he came along. “The moon will soon be rising, and we may get some benefit of her light, though that does not matter much.”

He was told about the letter, and seemed to feel a good deal like Hugh in that it had better not be opened, save as a last resort. If other things failed them, and no signs of the missing Felix could be found, then it would be time enough to think of breaking the seal.
