"I have your confidence?"
"Yes."
"Can we not arrange signals between us?"
"Certainly."
"I am going to start in as a regular detective in this affair, and at any moment I may want to signal to you; yes, warn you in case anything appears to be going wrong at a critical moment."
"I am delighted to work with one as shrewd and thoughtful as you are," said Oscar.
"Can you not come to my home to-morrow?"
"I fear I will not have time."
"We must practice those signals. I will not ask you to visit me across the river. I have the privilege of receiving company at the rooms of a friend of mine in this city. If we could meet there some time to-morrow morning, you might bring one or two of your friends with you and we will practice the signals together."
"All right, it is not a bad idea."
