“What’s robust?”

Wolfe made a face. “I’ll try to use words you have met before, but when I don’t, when one of them is a stranger to you, kindly do not interrupt. If you are smart enough to be a good detective, you are smart enough to guess accurately the meaning of a new word by the context — which means the other words I use with it. Also there is usually a clue. A moment ago I spoke of a healthy and hardy ego, and then, after your interruption, I spoke of a robust ego in the same connection. So obviously ‘robust’ means ‘healthy and hardy,’ and if you have the stuff of a good detective in you, you should have spotted it. How old are you?”

“Twelve.”

“Then I should make allowances, and do. To continue: with a robust ego, your feeling about earning your fees can safely be left to your intelligence and common sense. Never collect or accept a fee that you feel you haven’t earned; if you do, your integrity crumbles and your ego will have worms. With that one reservation, get all you can. As you must not take what you feel you haven’t earned, so must you get what you feel you have earned. Don’t even discuss a case with a prospective client until you know about his ability to pay. So much—”

“Then why—” Pete blurted, and stopped.

“Why what?”

“Nothing. Only you’re discussing with me, just a kid.”

“This is a special case. Mr. Goodwin brought you in to me, and he is my trusted and highly valuable assistant, and he would be disappointed if I didn’t explore your affair thoroughly and let him take it down and type it.” Wolfe favored me with a hypocritical glance and returned to Pete. “So much for your ego and your fees. As for your methods, they must of course be suited to your field. I pass over such fields as industrial espionage and divorce evidence and similar repugnant snooperies, since the ego of any man who engages in them is already infested with worms, and so you are not concerned. But take robbery. Say, for instance, a woman’s jewel box has been looted, and she doesn’t want to go to the police because she suspects—”

“Let’s take murder. I’d rather start with murder.”

“As you will.” Wolfe was gracious. “You’re getting this, are you, Archie?”
