"Has such a one been stolen from you?"
"Not to my knowledge."
"Then you have no idea how your property came where it was this morning found?"
"You are seeking facts, sir, not ideas."

"Doctor Heath, will you look at this knife?"
The doctor steps promptly forward and receives it from his hand.
"Did you ever see that knife before?"
