"In that case they know we are here on their trail?"

"Yes. Every move you make is being keenly watched by spies."

"Our enemies must be well-disguised and keep well under cover."

"You haven't thus far detected them, have you?"

"No," admitted Old King Brady.

"Then that shows how secure they are. A number of times they have been as
close to you as I am. Yet you did not know it. By this you can realize how
easy it would be for them to attack you unexpectedly, kill you, and
escape."

"Even that thought won't scare me off the case."

"You are very obstinate and persevering."

"Those two elements will yet make me win this fight."

"Foolish man. Don't delude yourself. Your enemies are very powerful people.
They will beat you in the end."

"I don't agree with your idea."

"Is my warning in vain?"

"Entirely so."
