Owen started looking at the white labels on the metal boxes along the left wall, while I took the opposite side of the vault, scanning first one shelf, then another. All the while, I was counting off the seconds in my head. It wouldn’t be too long before Clementine realized that she’d been tricked and headed back this way. We needed to be out of the vault by then, or we were dead. But we also needed to find whatever she was after. Otherwise, we’d have no leverage to use to free the hostages.

A minute passed, then two. But all I saw were paintings, jewelry, more small statues, and a couture dress made of crimson feathers and adorned with rubies that was draped over a mannequin in the back corner. Well, Finn certainly would have considered that valuable enough to store inside the vault. And it was even in my color. Heh.

“Anything?” I asked.

Owen shook his head. “Nothing that jumps out at me. You?”

“Same.”

Owen turned toward the wall of boxes again, but I took a step back and examined the vault. We could look for an hour and not find what Clementine had been after, and the giant and her men would return any second. As my gaze flicked from one shelf to another, I realized something important, something I should have remembered before now: that the inside of the vault was made of marble, just like the rest of the museum. An idea popped into my head of a way that I could at least narrow down our search area. I leaned forward, laid my hand on the wall closest to me, and reached out with my magic, concentrating on all the whispers of the stone.

The stone walls hummed with various emotions, mostly lofty pride and haughty arrogance at all the precious things they had housed and kept safe over the years. But those feelings were also mixed with notes of sweet relief, as the museum staff had been glad when certain items had been moved elsewhere so they wouldn’t be held responsible for them anymore. I reached for more of my magic and let myself sink even deeper into the stone, straining to hear every single thing I could from the marbles walls, every harsh note, every soft whisper, every sly murmur.

And I finally found something—a suspicious mutter that was just a little louder and just a little sharper than all the others. I trailed my fingers over the smooth stone, following the echo of that mutter like notes on a roll of sheet music. The sound led me all the way over to a shelf in the back of the vault. To my surprise, there was only one item on this shelf: a tube made out of ebony.
