“He’s my brother-in-law,” Carruthers improvised. “Egbert.”

“My wife tried to get me to hire her brother to work on the fire watch,” the verger said, shaking his head sympathetically. “Can’t walk across the kitchen without tripping over the cat. ‘How’s he supposed to put out incendiaries?’ I asks her. ‘He needs a job she says. ‘Let Hitler put him to work,’ I says.”

I left them to it and started down what had been the nave. There was no time to lose. We’d gotten here late, and even though it was only a bit past four, the smoke and masonry dust in the air already made it almost too dark to see.

The recruit had given up on his pocket torch and was watching Mr. Spivens digging determinedly into the rubble next to the steps. I sighted along him to determine where the north aisle had been and started working my way toward the back of the nave.

The bishop’s bird stump had stood on a wrought-iron stand in front of the parclose screen of the Smiths’ Chapel. I picked my way over the rubble, trying to work out where I was. Only the outer walls of the cathedral and the tower, with its beautiful spire, were still standing. Everything else — the roof, the vaulted ceiling, the clerestory arches, the pillars — had come crashing down into one giant unrecognizable heap of blackened rubble.

All right, I thought, standing on top of a roof beam, that was the apse, and along there was the Drapers’ Chapel, although there was no way to tell except by the blown-out windows. The stone arches had come down, and there was only the bayed wall left.

And here was the St. Laurence Chapel, I thought, scrabbling over the rubble on my hands and knees. The clutter of stone and charred beams was five feet high in this part of the cathedral, and slippery. It had drizzled off and on all day, turning the ash to blackish mud and making the lead slates from the roof as slick as ice.
