“Can Fred Reade have anything to do with this mysterious happening?” asked Billy.

“Eh, say that name again, young man,” demanded the inventor, who was, besides being often preoccupied, somewhat deaf and so had not heard Billy mention the other’s name when they were in the auto.

“I said Fred Reade,” rejoined Billy. “Why, do you know him?”

“I do, and I know no good of him,” was the reply. “It was he that first approached me in connection with the sale of the Buzzard to Luther Barr and——”

“Luther Barr again. We seem to cross his trail all the time,” exclaimed Frank.

“Eh?” questioned the old man, his hand at his ear, trumpet-wise.

“I said we have heard of Luther Barr before, as you know,” said Frank, “but you never mentioned the fact that Reade had acted for him.”

“It must have slipped my mind in the excitement,” explained the old man. “Yes, Fred Reade has acted for Barr in many matters that I know of.”

“A sort of agent of his,” said Billy.

“More than that,” rejoined old Eben Joyce; “there is some mysterious tie between them. I think Reade knows something about Luther Barr that the other is afraid will come out.”
