“They found something more important than us.�

“We’re going back!�

“No! I don’t think we had better do that.�

“I’d like to know,� he admitted, staring in the direction of the House of the Two Lions. “I’d almost take a chance to find out.�

“Come on back. We’ll soon know. It’s the only thing to do, Chester.�
