“He is very likely in his room just now. Let us work the surprise on him. Fate seems to have played this into our hands.”

“Harry,” said Old King Brady, “we must proceed with due caution. You can slip out now and get an officer.”

“I will go down and look on the register and get the number of his room.”

“Very well.”

“Then I will meet you at the Tremont street door. Do you see?”

“Yes.”
