I did not glance at McKnight. I felt that the hand, with which I was gathering up the bits of torn paper were shaking. It seemed to me that this astute little man was going to drag in the girl in spite of me.

CHAPTER XVIII.
A NEW WORLD

Hotchkiss jotted down the bits of telegram and rose.

“Well,” he said, “we’ve done something. We’ve found where the murderer left the train, we know what day he went to Baltimore, and, most important of all, we have a motive for the crime.”

“It seems the irony of fate,” said McKnight, getting up, “that a man should kill another man for certain papers he is supposed to be carrying, find he hasn’t got them after all, decide to throw suspicion on another man by changing berths and getting out, bag and baggage, and then, by the merest fluke of chance, take with him, in the valise he changed for his own, the very notes he was after.
