"Don't you think that if I had seen any one I would have said something about it?"

"How do I know? You might—"

"Might what? If you think I know who did it, say so right out," snapped Nat, his brown eyes flashing.

"Sam didn't say anything like that," interposed Bob.

"He'd better not," blustered Nat, in war-like tones; "nobody can insult me!"
