situation, all right," Frank
said. "But you said 'one of the men who visited the rooms that night.'
Who were the others?"

"Wait a minute," said Nestor. "Let me tell you what else I found
there. I have in my pocket a piece of paper, a margin cut from a legal
document, showing the thumb and fingermarks of a withered right hand.
I also have a shoe heel near two inches high. These were taken from
the Cameron suite. What do you make of that?"

"I understand," Frank said. "One of the other men was this Mexican,
the man with the short right leg, the fellow who tried to geezle me at
the El Paso restaurant. Well, that makes two who were there that
night--two who were in front of the safe--two who had no right to be
there."

"And this Mexican was a tenant of the building," Nestor went on, "and
he might have had the key made. At least he was there the night the
key was used, looking over papers he had no right to touch."

"It begins to look as if the Mexican went to the building for the
purpose of robbery, and that he found a tool in Jim Scoby," said Frank.
"Why don't you have the two of them pinched, so Fremont won't have all
this trouble on his mind? The Mexican is somewhere about here, and Jim
Scoby can't be far away, as the newspapers say he ran away from New
York. Why couldn't you have studied this out that night?"

"Don't rush conclusions," smiled Nestor. "I said there were several
people in the suite that night. Well, we have made sure of two of
them, though we don't know how they go in there if Mr. Cameron had the
door locked from the inside."

"If they hadn't used their false key," Shaw put in, "they wouldn't have
had it in hand and wouldn't have lost it."

"Very clever," said Nestor.

"Who else was in there?" asked Frank, blushing at the compliment.

"The third man," Nestor continued, "had business with Mr. Cameron. He
was there earlier in the evening."

"He didn't lose anything there, did he?" asked Frank, with a laugh.

"Yes," replied Nestor, "he did. He lost his temper."

"You're a corker!" Frank exclaimed. "What else did he lose?"

"His life, possibly."

"Come, children," Frank grinned, "it is time to wake up."

CHAPTER IX.

ABOUT THE THIRD SUSPECT.

Nestor laughed at the puzzled boy's exclamation and sat for some time
looking down on the dim camp-fire near the tents he had visited a short
time before. The night was cloudless, with a slight wind blowing from
the west. Now an
