Don Miguel was now walking fiercely about the little dent in the side of the mountain where the camp was built, pressing close to the loaded guns of the guards, each time, before he turned back to swing and rave over the ground again.

"This very pretty conspiracy to involve the United States in a war with Mexico," Nestor continued, "was unwittingly foiled by a desperate crime—perhaps committed by yourself."

CHAPTER XV.

ACCUSING EACH OTHER.

Don Miguel stopped in his nervous pacing of the small space in front of the tents and thrust his passion-swept face to within a foot of that of the speaker.

"A desperate crime!" he repeated. "Do you have the temerity to mention my name in connection with crime?"

"On the night of your visit to Mr. Cameron," Nestor went on, coolly, "you dined at one of the famous lobster palaces on Times Square. Early in the evening, let us say not far from nine o'clock, you left the restaurant and took a cab for the Cameron building. You spoke both French and Spanish to the driver, as well as English, and tipped him liberally, paying the charge in gold."

Don Miguel swung away again, his face expressive of a desire to do murder.

"You found Mr. Cameron in his office," Nestor continued, "busy with the papers of the Tolford estate. There are only two persons who know what took place at that interview, Mr. Cameron and yourself, but we are certain that the purpose of it was to urge Mr. Cameron to complete the contract for munitions of war which was under discussion. It is also quite likely that, failing in this, you sought the return of the compromising letters which you had written to him."
