“The plan to destroy St. Paul’s. They’ve already tried once. The tenth of September. A high explosive bomb. But of course you didn’t know about that. You were in Wales.”

I was not even listening. The minute he had said “high explosive bomb,” I had remembered it all. It had burrowed in under the road and lodged on the foundations. The bomb squad had tried to defuse it, but there was a leaking gas main. They decided to evacuate St. Paul’s, but Dean Matthews refused to leave, and they got it out after all and exploded it in Barking Marshes. Instant and complete retrieval.

“The bomb squad saved her that time,” Langby was saying. “It seems there’s always somebody about.”

“Yes,” I said, “there is,” and walked away from him.

October 1—I thought last night’s retrieval of the events of September tenth meant some sort of breakthrough, but I have been lying here on my cot most of the night trying for Nazi spies in St. Paul’s and getting nothing. Do I have to know exactly what I’m looking for before I can remember it? What good does that do me?

Maybe Langby is not a Nazi spy. Then what is he? An arsonist? A madman? The crypt is hardly conducive to thought, being not at all as silent as a tomb. The chars talk most of the night and the sound of the bombs is muffled, which somehow makes it worse. I find myself straining to hear them. When I did get to sleep this morning, I dreamed about one of the tube shelters being hit, broken mains, drowning people.

October 4—I tried to catch the cat today. I had some idea of persuading it to dispatch the mouse that has been terrifying the chars. I also wanted to see one up close. I took the water bucket I had used with the stirrup pump last night to put out some burning shrapnel from one of the antiaircraft guns. It still had a bit of water in it, but not enough to drown the cat, and my plan was to clamp the bucket over him, reach under, and pick him up, then carry him down to the crypt and point him at the mouse. I did not even come close to him.
