Eyrie."

"Yes, the threat of death! But Strock, you have had this letter for a
month. Why have you not shown it to me before?"

"Because I attached no importance to it. Today, after the letter from
the 'Terror,' it must be taken seriously."

"I agree with you. It appears to me most important. I even hope it
may prove the means of tracking this strange personage."

"That is what I also hope, Mr. Ward."

"Only what connection can possibly exist between the 'Terror' and the
Great Eyrie?"

"That I do not know. I cannot even imagine."

"There can be but one explanation," continued Mr. Ward, "though it is
almost inadmissible, even impossible."

"And that is?"

"That the Great Eyrie was the spot selected by the inventor, where he
gathered his material."

"That is impossible!" cried I. "In what way would he get his material
in there? And how get his machine out? After what I have seen, Mr.
Ward, your suggestion is impossible."
