“Please. What’s the wipe racket?”

“Why, you know, a car stops for the light and you hop to it with a rag and start wiping the window, and if it’s a man and he lets you go on to the windshield you’ve got him for at least a dime. If it’s a woman and she lets you go on, maybe you’ve got her and maybe not. That’s a chance you take. Well, this Caddy stopped—”

“What’s a Caddy?”

From the look that appeared in the sharp black eyes, Pete was beginning to suspect that he had picked the wrong private eye. I cut in to show him that anyhow one of us wasn’t a moron, telling Wolfe, “A Cadillac automobile.”

“I see. It stopped?”

“Yeah, for the light. I went for the window by the driver. It was a woman. She turned her face around to me to look straight at me and she said something. I don’t think she made any sound, or anyway if she did I didn’t hear anything through the window because it was up nearly to the top, but she worked her lips with it and I could tell what it was. She said, ‘Help. Get a cop.’ Like this, look.”

He made the words with his lips, overdoing it some, without producing any noise. Wolfe nodded appreciatively. He turned to me. “Archie. Make a sketch of Pete’s mouth doing that pantomime.”

“Later,” I said obligingly. “After you’ve gone to bed.”

“It was plain as it could be,” Pete went on. “‘Help, get a cop.’ It hit me, it sure did. I tried to keep my face deadpan, I knew that was the way to take it, but I guess I didn’t, because the man was looking at me and he—”

“Where was the man?”
