"Thank you," was my answer.
"And you, sergeant. I will be pleased to have you, too," continued Mr. Harrison, turning to the officer.
"You're kind, Mr. Harrison, but duty calls me elsewhere. I'll have to return to the station. But you've forgotten one thing."
"What?"
"That you can telegraph to New York and have the two men arrested as soon as they arrive."
"That's so! What do you say, Strong?"
I thought for a moment. It would be the simplest way to do, but would it be the best?
"Don't you think we had better let them go ahead?" I returned. "We know exactly where they are going, and by following them up may gain some additional information."
"I don't know but what you are right," replied Mr. Harrison.
"Then, in that case, my duty here is at an end," said the sergeant.
