The sixpenny print of The Light of the World caught fire, the edges curling up, the shut door in the picture burning away to black, to ash. Polly darted down the aisle to the nearest pillar, snatched up one of the pails of water, heaved the contents over the desk and the burning print, and then ran back to fill it again from the tin tub.

But the first pailful had put the fire out. She poured the second pail over the counter and the card rack for good measure, then pulled the postcards out of the rack and threw them and The Light of the World onto the floor several feet from the desk in case the fire wasn’t completely out.

She set the bucket down and ran back to the staircase and up the twisting steps, round and round, to the gallery above.

It was even more full of smoke and ash and cinders. And it will get worse as you go up, Polly thought, ducking her head to protect it from the embers as she ran along the gallery, trying doors, searching for a stairway which would take her farther up. A library. A closet, filled with choir robes.

The stairway must be in the transept, she thought, and hurried toward the dome.

It was in the transept, just past the corner of the gallery. It led up to a dark and stiflingly hot corridor roofed with low wooden beams that she had to duck under and huge bumps in the floor she had to edge around or crawl over. The tops of the arches’ vaults?

But she must be going the right way, because coils of hose and tubs of sand and water stood every few yards against the walls and, in one case, in the middle of the corridor. She splashed into it as she tried to step over a hump, and it was only then that she realized she was still in her stocking feet and her shoes were still in her pockets. She sat down next to the tub, put her shoes on and went on, looking for a stairway leading farther up.

She finally found one. It led up to a maze of even lower-roofed, narrower, and smokier passages that had to be just beneath the roofs. She could hear planes and anti-aircraft guns through the ceiling.

And voices, coming from farther along the passage and above her. “Easy, easy,” she heard one voice say, and then a second voice from a bit below the first, saying, “Watch the turning.”

They’re coming down a flight of stairs, Polly thought. And they were no more than a few feet away, which meant this passage had to connect to the stairs. She scuttled along the passage, trying not to crack her head against ceiling beams she could only half see in the dimness, straining to spot the doorway to the stairs.

“No, no, you’ll—” the first voice said.

“Come back this way.”

And the other said, “Wait, I haven’t got a good grip.”
