"I don't suppose it will do me any good to ask where you have been."

"Oh, I won't mind telling you, now we are over here. I have been up to the Widow Glenn's house."

"I see it almost overwhelms you to think a Southern spy could get close to Union headquarters. A clever trick did it—a trick I learned when I was in the detective bureau at Washington."

"Look at something else?"
