I knew I must tell him that if I let go, St. Paul’s and all the past would fall in on me, and that I must not let that happen because I was an historian. I said something, but it was not what I intended because Langby merely tightened his grip. He hauled me violently free of the railing and back onto the stairway; then let me collapse limply on the steps and stood back from me, not speaking.

“I don’t know what happened in there,” I said. “I’ve never been afraid of heights before.”

“You’re shaking,” he said sharply “You’d better lie down.” He led me back to the crypt.

September 25—Memory retrieval: ARP manual. Symptoms of bombing victims. Stage one-shock; stupefaction; unawareness of injuries; words may not make sense except to victim. Stage two-shivering; nausea; injuries, losses felt; return to reality Stage three-talkativeness that cannot be controlled; desire to explain shock behavior to rescuers.

Langby must surely recognize the symptoms, but how does he account for the fact there was no bomb? I can hardly explain my shock behavior to him, and it isn’t just the sacred silence of the historian that stops me.

He has not said anything, in fact assigned me my first watches for tomorrow night as if nothing had happened, and he seems no more preoccupied than anyone else. Everyone I’ve met so far is jittery (one thing I had in short-term was how calm everyone was during the raids) and the raids have not come near us since I got here. They’ve been mostly over the East End and the docks.

There was a reference tonight to a UXB, and I have been thinking about the Dean’s manner and the church being closed when I’m almost sure I remember reading it was open through the entire Blitz. As soon as I get a chance, I’ll try to retrieve the events of September. As to retrieving anything else, I don’t see how I can hope to remember the right information until I know what it is I am supposed to do here, if anything.
