"But why does he want the boy?"

"That is the mystery—if Jack is not really his son."

"Perhaps there is a fortune coming to your brother, and the doctor wants to secure it. A man like Dr. Mackey wouldn't do a thing of this sort without an object. I can tell you one thing—the fellow worships money."

"What makes you think that?"

"Because I know that a wounded soldier once told him to be careful and he would give him all the money he had—twelve dollars. The doctor was careful, and took every dollar that was offered."

"But had he a right to take the soldier's money?" asked Marion indignantly.

"Not exactly, but in war times many queer things happen that are never told of at headquarters," answered George Walden.

Here the conversation ceased, for the soldier was quite exhausted. Soon Marion gave him a quieting draught, and then George Walden slept.
