“That’s amazing,” I said. And even more amazing, I thought, was that I had managed to forget for a moment there that I already knew where the attaché case was. Ray Kirschmann had shown it to me yesterday, with an incomprehensible six-letter word printed on its side in blood.

“Ginkgo,” he said. “I recommend it.”

“Maybe I’ll get some. Except it’s not my memory that bothers me so much as the feeling I get sometimes that I’m not thinking too clearly.”

“It’s good for that, too. Mental clarity!”

“That’s what I could use.”

“Also a ringing in the ears.”

“It gives it to you or gets rid of it?”

“Gets rid of it!”

“Well, that’s good to know,” I said, “although that’s not something I’ve had to worry about.”

“Yet.”

“Yet,” I agreed. “Tell me about the woman and the monkey.”

He told me about the woman and the monkey in considerable detail, but I don’t know that it constituted much of a testament to his memory, or to the efficacy of ginkgo biloba. I’ve never touched the stuff myself, and I expect to remember the whole episode long into my dotage. All I’ll say is this-the woman had a well-developed figure (“Cantaloupes!” Max Fiddler said), while the monkey was a scrawny specimen with a mean little sour apple of a face. And they both should have been ashamed of themselves.

The story of their courtship carried us all the way to my corner. He was reaching to throw the flag when I told him to wait a minute.

“You said New York streets,” I said. “Anywhere in the five boroughs, you said.”

“So?”

“How about Arbor Court?”

“ Arbor Court,” he said. “There’s only one Arbor Court and it’s in Manhattan. Is that the one you mean?”

“That’s the one.”

“In the Village, right?”

“Right.”

“Child’s play,” he said. “I thought you’d give me something hard, like Broadway Alley or Pomander Walk, but the best you can do is Arbor Court. Do I know Arbor Court? Of course I know Arbor Court, and you could take away my ginkgo and I’d still know it.”
