Pete stopped brushing to raise his head. “Now, Mr. Wolfe. In God’s name.”

“I advise you to return. If a crowd had already gathered when you looked out the window, and if Miss Cox can fix the exact time you entered the room, you are probably not vulnerable, but you may be in a pickle. You should not have left the premises. The police will soon be looking for you. Go back at once. Mr. Goodwin’s shoes can wait till Wednesday-or come this afternoon.”

Pete put the brush down and got out the polish. “Cops,” he said. “They’re all right, I like cops. But if I tell a cop I saw someone-” He started dabbing polish on. “No,” he said. “No, sir.”

Wolfe grunted. “So you saw someone.”

“I didn’t say I saw someone, I only said what if I told a cop I did? Did they have cops in Athens in four-oh-three B.C.?” He dabbed polish.

That took the conversation back to the ancient glories of Greece, but I didn’t listen. While Pete finished with Wolfe and then shined me, ignoring Wolfe’s advice, I practiced on him. The idea that a detective should stick strictly to facts is the bunk. One good opinion can sometimes get you further than a hundred assorted facts. So I practiced on Pete Vassos for that ten minutes. Had he killed a man half an hour ago? If the facts, now being gathered by cops, made it possible but left it open, how would I vote? I ended by not voting because I would have had to know about motive. For money, no, Pete wouldn’t. For vengeance, that would depend on what for. For fear, sure, if the fear was hot enough. So I couldn’t vote.

An hour later, when I walked crosstown on an errand to the bank, I stopped at the corner at Eighth Avenue for a look. The smashed-up Mr. Ashby had been removed, but the sidewalk in front of the building was roped off to keep the crowd of volunteer criminologists from interfering with the research of a couple of homicide scientists, and three cops were dealing with the traffic. Looking up, I saw a few heads sticking out of windows, but none on the tenth floor, which was third from the top.
