"You are sure the boy was carried to St. Louis?"

"Quite certain."

"I might go to St. Louis, but without any clue I am afraid I should stand little chance of succeeding."

"You might advertise."

"That is true," said Mark. "Indeed, it appears to be the only thing I can do. How old would the boy be now?"

"About eight years old, I think."

"Thank you."

Mark took out a small memorandum book, and noted down the small amount of information he had obtained.

It did not appear to be much, and yet it was of great importance. He had ascertained that Mrs. Ransom had left a child, and moreover that Lyman Taylor had been aware of the fact, and had conspired to keep its existence from old Anthony.

"Does he know where it is now?" Mark asked himself.
