"What will happen to them?" I asked.

"What does it matter?" he snapped, letting me go. "They care nothing for you, why do you care for them?"

"Answer my question. What will happen to them?"

"I need their souls for you to do your work."

"You're going to kill them," I said flatly.

He pressed his lips together, as if he were summoning some patience. "The life of three enemies with vile intentions is worth exchanging for three of my creations."

"What if the souls refuse to help?"

"They cannot refuse." He frowned. "Do you not know the extent of your power? Charlotte, you control the spirits. They may have minds and wills of their own, but you command them. They must obey you."

I'd learned that much from Fitzroy's book, and now I knew that Frankenstein knew it too. He did not appear to realize that any spirit could be raised, not simply a newly deceased one. "Do you know that from my mother?"

He nodded. "She was a powerful necromancer."

I folded my arms and glanced at Seth and Gus, unconscious and unable to help me even if I managed to free them from their bonds. The third man's breath rattled in his chest, the skin surrounding the bruises paler than ever. Death clung to him, waiting.

Frankenstein checked the man's pulse. "It's almost time." He pushed the tables closer to the chairs and switched on the generator. It hummed to life. The three bodies on their iron thrones sat ready to receive their new souls—three dead bodies and three soon-to-be-dead ones, with only me to connect them.

"I'm not doing this."

Frankenstein didn't hear me over the increasing noise of the generator. He checked the glass panel and spun one of the dials. I glanced around again, searching for any sign that Fitzroy was near; that he was lying in wait to capture Frankenstein before the bodies became animated.

What if my arrival had ruined Fitzroy's plans? What if he had intended for Seth and Gus to be caught and he was right now lying in wait? But where?

Or was he already dead and therefore useless for Frankenstein's scheme?

"Come, Charlotte." Frankenstein had to shout over the drone of the generator as he moved to the tables. "Stand closer, so the spirit can hear you." He nodded at the dying man on the table while he stood between Seth and Gus. "It's almost time."

Electricity flashed and crackled along the wires like blue, life-giving veins. The fingers of all three creatures twitched, their arms jerked. Their eyelids fluttered. They would soon be awake.

"Charlotte! Now!" Frankenstein opened a medical bag sitting on the floor behind Seth's table and pulled out a dagger. When he turned back to me, his eyes were bright with fevered excitement and his lips battled with a triumphant smile. He pointed the dagger at the dying man. "Stand there!"

I moved to the side of the third table, and caught sight of the bloodied face. I gagged on my own bile and quickly turned away again.
