"I should have had to walk back. But, uncle, I can't leave you without a word of warning."

"Well?"

"That boy, Mark, I am sure is scheming to rob you."

"What do you know of Mark?"

"I know the reputation he bears in the town. I know he has been discharged from the shoe-shop."

"Who told you?"

"Two boys whom I met. One is the son of Mark's employer."

"I know the boys you mean. They dislike Mark, but I prefer him to them."

A noise was heard at the door, and Mark entered.

He looked in surprise at the visitor, whom he instantly recognized.
