Continental Plastic Products might be a giant with three or four floors, or it might have two small rooms with the only phone on the executive vice-president's desk. Even so, I knew that block of East 68th Street, and it was no slum, far from it. This character might wear a $39.95 suit because he didn't give a damn and didn't have to. I know a chairman of the board of a billion-dollar corporation, one of the 2 per cent, who never gets his shoes shined and shaves three times a week. I had my notebook and was writing in it. Yeager was saying, "My phone number is not listed. It's Chisholm five, three-two-three-two. I came at a time when I knew Wolfe would be busy, to see you, because there's no point in explaining it to him since he would merely assign you to it. I think I am being 4 Rex Stout followed, and I want to make sure, and if I am I want to know who is following me." "That's kindergarten stuff." I tossed the notebook on my desk. "Any reputable agency will handle that for you at ten dollars an hour. Mr. Wolfe has a different approach to the fee question." "I know he has. That's unimportant." He waved it away. "But it's vitally important to find out if I'm being followed, and quickly, and especially who it is. What agency at ten dollars an hour would have a man as good as you?" "That's not the point. Even if I'm only half as good as I think I am it would still be a pity to waste me on spotting a tail. And what if there's no tail to spot? How long would it take to convince you? Say ten days, twelve hours a day, at a hundred dollars an hour. Twelve thousand bucks plus expenses. Even if you--" "It wouldn't be ten days." He had lifted his chin. "I'm sure it wouldn't. And it wouldn't be twelve hours a day. If you'll let me explain, Mr. Goodwin. I think I am being followed only at certain times, or that I will be. Specifically, I suspect that I shall be followed when I leave my house this evening at seven o'clock to go crosstown, across the park, to an address on Eighty-second Street.
