He looked reproachful. "Oh, come now," he pleaded. "Something must have happened. You got out of Harlem like a bat out of hell and almost shook the agent who was tailing you. You don't look to me like nothing happened. Have you filled in that gap? Started to remember anything?"

"On my word of honor, Andy," I swore, "I haven't remembered a thing. The gap's still there."

He said nothing for a few minutes and exchanged a glance with Arthurjean.

"Something must have happened," he requested. "You've changed. Come clean, can't you? I'm only trying to help you."

"I can't tell you much of anything," I told him. "You wouldn't believe me if I did. There's been a sort of locked door inside my mind for the last three weeks. Now the door's unlocked and is beginning to swing open. I haven't looked inside, but I think I know what I'll find. I can't tell you more than that now."

"But you're going to look, aren't you?" he asked.

"I've got to look," I said.

He sighed. "Well, we'll just have to keep an eye on you so as to be around when you do. See here, Mr. Tompkins, you know your own business but this Von Bieberstein guy is nobody to monkey around with. He's plenty tough and he'd as soon kill as sneeze. Can't you give me a hint? I'm trained to take those risks and know how to take care of myself, and anyhow the Bureau is back of me."

I leaned back in my chair and laughed and laughed and laughed until I noticed that both Arthurjean and Harcourt were staring at me without smiling.

"Sorry," I apologized. "It's just that something struck me as rather funny. Well, Arthurjean, I'll be catching the train back to Westchester. You and Andy blow yourself to a dinner at my expense. I'll go down to the vet's first thing in the morning and follow your advice. Good night, Andy. I'll be seeing you."
