“Nothing at all?”

“Nothing.”

“I won’t tell the police what I told you, but that doesn’t matter. If you haven’t, you will.” Suddenly she was on her feet with her arms spread out. “Oh, I need you! I need to ask you — I need to tell you what I must do! But I won’t! I won’t!” She turned and was gone. She moved so fast that when I got to the hall she already had the front door open. By the time I reached it she was out and the door was shut. Through the one-way glass panel I saw her going down the steps, sure and supple, like a fencer or a dancer, which was reasonable, since she had been both.

That was the last we saw of her during the three weeks, but not the last we heard. Word of her came four days later, Friday morning, from an unexpected quarter. Wolfe and I were having a session in the office with Saul and Fred and Orrie, one of a series, trying to think up some more stones to look under, when the doorbell rang and a moment later Fritz entered to announce, “A man to see you, sir. Mr. Stahl of the Federal Bureau of Investigation.”

Wolfe’s brows went up; he glanced at me, I shook my head, and he told Fritz to bring the man in. The hired help, including me, exchanged glances. An FBI man was no rare spectacle for any of us, but Stahl wasn’t just one of the swarm; he had worked up to where he gave more orders than he took, and the word was that by Christmas he would be occupying the big corner room down at 290 Broadway. He didn’t often go out to run errands, so it was quite an event for him to drop in, and we all knew it and appreciated it. When he entered and marched across to Wolfe’s desk and offered a hand, Wolfe even did him the honor of rising to shake, which showed how desperate the situation was.

“It’s been quite a while since I saw you last,” Stahl observed. “Three years?”

Wolfe nodded. “I believe so.” He indicated the red leather chair, which Fred Durkin had vacated. “Be seated.”

“Thank you. May we make this private?”

“If necessary.” Wolfe glanced at the trio, and they got up and filed out and shut the door. Stahl went and sat. Medium-sized and beginning to be a little short on hair, he wasn’t impressive to look at, except his jaw, which came straight down a good two inches and then jutted forward. He was well designed for ramming. He gave me a look, and Wolfe said, “As you know, Mr. Goodwin is privy to all that I hear and see and do.”

Stahl knew no such thing, because it wasn’t true. I’d like to have a nickel — or make it a dime, with the dollar where it is — for every item Wolfe has withheld from me just for the hell of it.
