What does that lead up to?"
"I found this key in front of the safe," Nestor continued, after a moment's deliberation. "It was undoubtedly dropped there by one of the men who visited the rooms that night. I have been wondering if it was the watchman.""You have some other reason for supposing it was Scoby," Frank said. "Go one and tell me about it.""Yes, there is another reason." Nestor continued, smiling at the quick way Frank had taken him up. "I found this Grand Army button and this cloth raveling in front of the safe, too, not far from where the key was discovered.""Well, did the watchman wear a Grand Army coat that night?" asked Frank.
"Lots of unworthy people wear Grand Army coats.""He did," was the reply. "He wore a blue coat with Grand Army buttons, and one of the buttons was missing from the right sleeve when I saw him in the corridor as I passed out. He probably caught his sleeve on something in the safe and ripped the button off. He either did not notice the loss of the button or had no time to pick it up.""You're locating him in a compromising 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."
