From the book:
Mr. Judkins, the station agent at Chazy Junction, came out of his little house at daybreak, shivered a bit in the chill morning air and gave an involuntary start as he saw a private car on the sidetrack. There were two private cars, to be exact - a sleeper and a baggage car - and Mr. Judkins knew the three o'clock train must have left them as it passed through. "Ah," said he aloud; "the nabobs hev arrove." "Who are the nabobs?" asked a quiet voice beside him. Again Mr. Judkins started; he even stepped back a pace to get a better view of the stranger, who had approached so stealthily through the dimlight that the agent was unaware of his existence until he spoke.
