“Robert Thatcher.”

The tramp whistled, as if to express his surprise and amazement.

“Did you know him?” Tom repeated.

The stranger answered guardedly:

“I heard that such a man was at work with John Simpson.”

“And you saw him?”

“I believe I saw him once.”

“Do you know what became of him?”

“Do I know what became of him? I suppose he came home.”
