“What circumstances?”

“If you will excuse me, sir, I had rather not tell that.”

“Oh, certainly, my little friend, you need not tell anything unless it suits you. Do you know the lady in the black domino?”

“Yes, sir.”

“Would you object to tell me who she is?”

“I could not do it without her consent; I think she does not want her name known just now.”

“I will give you this twenty-dollar bill if you will tell me her name.”

“I beg you will excuse me, sir.”

“I will give you a hundred dollars if you will tell me who she is.”

“I could not do it, sir, if you were to offer me a thousand dollars!”
