“We only know that he was not there at daybreak,” was the reply, “and so we brought you away. Why did he leave so suddenly?”

Frank looked the Colonel in the eyes unflinchingly, determined to have the truth out of him, and asked:

“And so you don’t know where he is now?”

The Colonel did not reply, and Frank knew that there was no necessity for continuing the conversation. He was satisfied that the Colonel was one of the plotters, perhaps the leader, that Ned’s departure from the cottage had not been detected by the man he had followed into the jungle, and that his friend, at least up to daybreak, had not fallen into the hands of the enemy.

He saw in an instant how the case stood. The plotters, spying about the cottage at daybreak, had noted the absence of Ned. Fearful that he had departed on some errand which might seriously affect their own interests, they had resolved to bring the others away and learn from them, if possible, where Ned had gone.

As the reader has doubtless suspected, this was the exact truth. The plotters, at the time the boys were taken from the cottage, did not know where Ned was. He had not been seen following the would-be murderer, nor had any information from the bomb-boom disclosed his presence there.

Colonel Sharrow had regarded the “pumping” of the boy as certain of success, and was not a little surprised when he failed to go into the details of the incident which had taken Ned and Jimmie away from the cottage. It had seemed certain to him that the boy would hasten into an excited account of the peril of the situation. He did not know how the bomb had been discovered, or how it had been taken from under the floor of the cottage, but he knew that it had been done.

He had depended upon Frank to tell him all about it, and to explain where Ned had gone and why he had left the cottage in the night. He was greatly worried over the disappearance of the boy, for he did not know what had been discovered regarding the attempted destruction of the cottage and the consequent murder of the boys. He did not know what steps Ned might be taking to discover the author of the attempted outrage of the previous night. Besides, he was curious to know just how the destruction of the cottage had been averted.

“We do not know where Ned is,” the Colonel said, in reply to Frank’s question. “We thought you might assist us in finding him.”

“How?” was the sharp demand.
