5. The Mistake of the Machine (continued)

"I'm sorry," said the other. "I only point out what seems a reasonable possibility. If you could tell by his manner when the word that might hang him had come, why shouldn't he tell from your manner that the word that might hang him was coming?

By the time I came with him out of the private room into the vestibule where all sorts of other people were awaiting examination, I think he had already more or less made up his mind to clear things up by something like a confession.
