At the left of the apartment, from which two others opened, to right and left, was a small safe, used privately by Mr. Cameron. Its usual place was against the wall, but it had been wheeled about so that it fronted the windows. The door was open, and, although no violence seemed to have been used, Fremont saw that the interior was in a mess, papers and books being scattered about in confusion.

At the right of the room, and near the doorway opening into the north room, stood a large flat-topped desk, most of the drawers of which were now open. One of the drawers lay on its side on the floor, and was empty. The articles on the desk's top gave evidence of rough handling. Papers appeared to be dripping from filecases, and a black pool of ink lay on the shining surface of the desk.

A swivel-chair which had stood in front of the desk was overturned, and its back now rested on the rug while its polished castors stuck up in the air. At first glance, there seemed to be no human being in the suite save the frightened boy.

With his mind filled with thoughts of robbery, George was about to rush out into the corridor and summon assistance, when a slight sound coming from the north room attracted his attention. He hastened thither, and was soon bending over an office couch upon which lay a still figure.

There was no longer doubt in the mind of the boy as to what had taken place there. Mr. Cameron had been attacked and the suite ransacked. The boy recalled the fact that the rooms had been lighted from within when he stood on the pavement, and wondered if it would not be possible, by acting promptly, to capture the assassin, as he must still be in the building, possibly hiding in some of the dark corners.

First, however, it was necessary that the injured man should receive medical help. Fremont saw a wound on the head, probably dealt with some blunt instrument, and then moved toward the telephone in the outer room. As he did so the corridor door was opened and a boy of perhaps fifteen years looked in. When the intruder saw that Fremont was observing him, he advanced to the connecting doorway.

For quite a minute the boys, standing within a yard of each other, remained silent. Fremont would have spoken, but the accusing look on the face of the other stopped him. The intruder glanced keenly about the two rooms which lay under his gaze and finally rested on the figure on the leather office couch. Then, while Fremont watched him curiously, he went back to the corridor door and stood against it.

"You've got your nerve!" he said, then. "You're nervy, but you ain't got good sense, doin' a think like that with the shades up, the lights on, an' the door unlocked. What did you go an' do it for?"

The sinister meaning of the words took form in the mind of the boy instantly. For the first time he realized that he would be accused of the crime, and that circumstances would be against him. If Mr. Cameron should never recover sufficiently to give a true account of what had taken place, he would be arrested and locked up as the guilty one.

If his benefactor should die without regaining consciousness, he might even be sent to the electric chair, and always his name would be mentioned with horror. While these thoughts were passing through the dazed mind of the boy, there came, also, the keen regret that Frank Shaw had not accompanied him to the building. That would have changed everything—just one witness.
