“The top page is missing.” He strides over and pulls the neck of my shirt aside. Instinctively, I reach for the key. But I already know it’s missing.

“She took the copy of the symbols and their translations from my backpack,” Luka says grimly.

“What symbols?” Claudia says.

In my anger, which is only a thin disguise for the fear turning my fingertips to ice, I round on Claudia. “I go to sleep for what—three hours? And crazy Tibor declares some war against Nikola, she shows up with a laptop as though none of this is bad enough that we need a digital trail, too, and Ana goes missing with a drawing of the symbols on my back. What genius felt the need to draw them over and over anyway before she ran off with my key?” I demand. “How many different ways can we try to get ourselves killed?”

“Audra—” Luka says, gesturing at me.

I glance down at myself, and then at the pencil in my hand.

My sleepwalking activities have returned. That, and I’m such an ass.

“What symbols?” Claudia says, as Jester’s laptop chirps.

I go into the bathroom to splash water on my face as Jester practically sprints across the room.

“I found her,” she calls out. In the mirror I see Luka and Claudia sit down on either side of her to stare at the screen. Claudia covers her mouth with a hand.

What now? I don’t think I can take any more of sucking so bad at being on the lam.

“She’s in Budapest.”

I stride out to the bed and sit next to Luka. “How do you know?” There, on the screen, is camera footage of a woman coming up out of a subway station in a pair of shades and what looks like one of Claudia’s wigs. Her face is covered with electronic dots, an image of her on a window to the right.

“How did you get this?”

“Jester has certain skills,” Claudia says. A minute later she’s on the phone with Piotrek speaking in clipped Croatian.

Jester’s a hacker?

“Where’s she going?” Luka says.

“She’s on the Buda side near the Danube,” Jester says with obvious dismay. “No, no—”

“No what?”

“Gellert Hill. She’s going underground,” Jester says, typing frantically.

“Then we can find her.”

“We’re about to lose her.”

“You just said you know where she is!”

“There’s a whole world under the Buda Hills! A church, bunkers, a complete World War Two hospital. Hundreds of cave systems, some kilometers long! Why do you think tracking Nikola is so difficult? Even the city doesn’t know everything that’s there. The Budapest princes have intentionally kept entire systems secret for centuries, going so far as to steal the city’s survey of the caves beneath Castle Hill in the late eighteen hundreds. As far as anyone knows, it disappeared and has never been found.”
