“Yes, sir! Oh, Mr. Stone, I knew you’d see it!”

“Boy, you are a wonder. Even if your deductions are all wrong, you have shown marvelous acumen.”

Fibsy had no idea what acumen was, nor did he care. He was not seeking praise, but corroboration, and he was getting it. The mark of a cane was perfectly clear and was unmistakable. It might mean nothing, but it was a cane mark, and some canes were murderous weapons.

“You have seeing eyes, child,” said Stone, and Fibsy desired no greater commendation.

“Now,” went on Stone, “I’m going to begin at the beginning of this thing and I propose to take you along with me.”

“Yes, sir, I’ll help,” and Fibsy settled back in his seat in the taxicab without a trace of presumption or forwardness on his freckled face or in his blue, ‘seeing’ eyes.
