It began then, because they didn’t get to the cloister. Not yet.

Going across, they heard a sound: metal on metal. A banging, a harsh scrape, another bang.

“What the hell?” Ned murmured, stopping where he was. He wasn’t sure why, but he kept his voice down.

Kate did the same. “That’s the baptistry,” she whispered. “Over there.” She pointed. “Probably one of the priests, maybe a caretaker.”

Another scraping sound.

Ned Marriner said, “I don’t think so.”

It would have been, in every possible way, wiser to ignore that noise, to go see the pretty cloister, walk out that way afterwards, into the morning streets of Aix. Get a croissant and a Coke somewhere with this girl named Kate.

His mother, however, was in the Sudan, having flown far away from them, again, to the heart of an insanely dangerous place. Ned came from courage—and from something else, though he didn’t know that part yet.

He walked quietly towards the baptistry and peered down the three steps leading into that round, pale space. He’d gone right past it when he came in, he realized. He saw eight tall pillars, making a smaller circle inside it, with a dome high above, letting in more light than anywhere else.

“It’s the oldest thing here,” whispered the girl beside him. “By a lot, like 500 A.D.”

He was about to ask her how she knew so many idiotic facts when he saw that a grate had been lifted from over a hole in the stone floor.

Then he saw the head and shoulders of a man appear from whatever opening that grate had covered. And Ned realized that this wasn’t, that this couldn’t be, a priest or a caretaker or anyone who belonged in here.

The man had his back to them. Ned lifted a hand, wordlessly, and pointed. Kate let out a gasp. The man in the pit didn’t move, and then he did.
