They must be carrying something between them. They were nearly even with her. She needed to hurry or she’d miss them. She rushed toward their voices.

And straight into a wall. The stairway lay on the other side of it—she could hear the two men only inches from her—but there was no door, no connecting link. The passage she was in dead-ended. And in the meantime, the men had already passed below her with their burden, their voices still repeating, “Easy” and “Careful,” as they got farther away. And now she had the entire maze to crawl back along, hoping she could remember the way she’d come and find a way out.

She was so focused on retracing her steps that she nearly missed the door. It stood behind an angled beam and was so narrow that she had to squeeze through it and up the shallow stone steps, not certain she wouldn’t get stuck as she did. The stairs ended in a trapdoor, which she had to push up mightily on with both hands to budge. It fell back, opening on the suddenly deafening roar of planes and a rush of heat and wind that blew her hat off. She grabbed for it, but the hat was already gone, caught in an updraft.

But it didn’t matter. She was through it and finally, finally, out on the roof.

On one of the roofs, she amended, pushing her blowing hair out of her eyes and looking at the long, flat roof and the stone wall and steep slant above her.

In spite of the distance she’d climbed, this was only one of the lower aisle roofs which ran the length of the nave. The pitched central roof and the dome were still a full story above her, and she had no way to get to them.

I’ll need to go all the way back down and find another way up, she thought despairingly.

But if an incendiary fell down here, they had to have a way to get to it quickly. There must be something here to make that possible—ropes or a ladder or something.

A ladder. It stood against the wall, hidden by the shadows of the transept roofs above it. She began to climb it.

Blustery as it had been on the aisle roof, the surrounding walls had protected her from the brunt of the wind. And from the cold. As she climbed higher, freezing gusts whipped around her, flapping the tail of her coat and blowing her hair across her face. She leaned forward to grab at the leaded gutter and then the parapet. Her foot accidentally kicked the side of the ladder as she pulled herself over the edge, and it fell away and down with a muffled clang.

Polly clutched at the parapet with both hands, squinting against the driving wind, and pulled herself up over it and onto the roof. The wind was even icier up here, though it shouldn’t have been. It was filled with darting sparks and flecks of fire and ash. She slitted her eyes against them and pulled herself to standing, holding on to a stone projection, and looked out over the edge of the roof.
