Wolfe shook his head. "Nothing right now. I wanted to see Madame Zorka and your son kindly made that possible."
"Yes, he told me about that. But what else?"
"Nothing at present. Really."
"Well." Barrett smiled. "I understand that as a private investigator you undertake almost any sort of job that promises a fee proportionate to your abilities."
"Yes, sir, I do. Within certain boundaries I have set. I try to keep my prejudices intact."
"Naturally." Barrett laughed sympathetically. "We can't leave it to anyone else to defend our prejudices for us." He tapped off ashes again. "My son also tells me that you are engaged in the interests of a young woman named Tormic who is a friend of his. At least-hum-an acquaintance. In connexion with the murder of that man Ludlow."
"That's right," Wolfe agreed. "I was originally engaged to clear her of a charge of stealing diamonds from a man named Driscoll. Then Mr Ludlow got killed, and Miss Tormic needed a little help on that too because she was implicated by circumstances."
"And was it from this Miss Tormic that you received information which enabled you to put pressure on my son? You did put pressure on him, didn't you?"
"Certainly. I blackmailed him."
"Yes. With a threat to disclose certain facts. Did you get those facts from Miss Tormic?"
"My dear sir." Wolfe wiggled a finger at him. "You can't possibly be fatuous enough to expect me to tell you that."
Barrett smiled at him. "There's always a chance that you might. Especially since there's no good reason why you shouldn't. Are you under obligation to defend the interests of anyone except Miss Tormic?"
"Yes. My own. Always my own."
"That, of course. But anyone else? I should think there would be no impropriety in your telling me if you represent any interest except that of Miss Tormic. For instance, Madame Zorka?"
Wolfe frowned. "I am always reluctant to make a present of information. Just as you are reluctant to make a present of money. You're a banker and your business is selling money; I'm a detective and mine is selling information. But I don't want to be churlish. In connexion with the activities we are speaking of, I represent no interest whatever except that of Miss Tormic."
"And, always, your own."
"Always my own."
