He spun, preparing to toss his torch aside and fight with his ashandarei, but saw nothing. The other two froze, looking about, anxious. Mat continued on sheepishly, though he felt less so after Thom did the same thing a short time later. Thom went so far as to throw a knife at a darkened patch of the wall.

The iron weapon clanked against the surface. The dull ring echoed for far too long in the hallway.

“Sorry,” Thom said.

“It’s all right,” Mat said.

“They’re watching us, aren’t they?” Noal asked. His voice was soft, faintly nervous. Light! Mat felt as if he was going to jump out of his skin and run away, leaving it behind. Compared to that, Noal seemed steady.

“I suspect they are, at that,” Mat said.

Within a few moments, they reached the end of the too-long hallway. Here, they entered a chamber that was identical to the first, save it had no doorway in the center. It split off in four directions, each corridor disappearing into the distant darkness.

They picked another direction, memorizing the path they were taking, unseen eyes scratching at their backs. His footsteps grew more hurried as they traversed the length of the hallway and entered another chamber. It was exactly like the previous one.

“Easy to be disoriented in a place like this,” Noal said. He opened his pack and got out a sheet of paper and a charcoal pencil. He made three dots on his paper, then connected them by lines, representing the corridors and rooms they’d gone through. “It’s all a matter of keeping a good map. A good map can mean life or death; you can trust me on that.”

Mat turned around, looking back the way they had come. Part of him wanted to keep going, not look backward, but he had to know. “Come on,” he said, going back the way they had come.

Thom and Noal shared looks, but once again hurried to catch up. It took them a good half-hour to retrace their steps back to the first chamber, the one that should contain the doorway. They found it empty. Those columns of steam rose from the corners. They had in the other two rooms, too.

“Impossible!” Noal said. “We retraced our steps perfectly! The way out should be here.”

In the distance—faint and almost inaudible—Mat heard laughter. A hissing, dangerous laughter. Malicious.

Mat’s skin grew icy. “Thom,” he said, “you ever hear a story about Birgitte Silverbow and her visit to the Tower of Ghenjei?”

“Birgitte?” Thom asked, looking up from his inspection—with Noal—of the floor. They seemed convinced that the doorway must have been pulled down into some hidden trapdoor. “No, can’t say that I have.”

“What about a story of a woman trapped for two months in a maze of corridors inside a fortress?”

“Two months?” Thom said. “Well, no. But there’s the tale of Elmiara and the Shadoweyes. She spent a hundred days wandering in a maze, looking for the infamous healing spring of Sund to save her lover’s life.”
