"That's a sheer impossibility," Harry answered. "They are taking the most extraordinary care not to let anyone hear a word they are saying or see a thing they are doing. I've tried several times, and failed."
"We've got a sharp gang to deal with, my boy. And the worst of it is that $250,000 worth of diamonds makes such a small package that they won't have the slightest trouble to conceal it."
"As they are not likely to allow so valuable a parcel to leave their hands, by arresting the whole gang the moment they reach the American side, we are likely to find the jewels on the person of one or the other."
"And I quite agree with that plan," said Harry. "In fact, it's the only safe method of securing them for a certainty."
"Have you noticed whether they made friends with any outsiders here?"
"No, they haven't. They keep strictly aloof from everybody. I made an attempt to speak to each one of the party in a friendly way at the table, but they gave me such a cold reception, I had to withdraw in a hurry."

Boarding a train for Toronto, they went away.
The Bradys were on the same train.
Once more their disguises were changed, for they did not want the smugglers to see them in Toronto in the same characters, as it might arouse their suspicions.
