“I love you too,” she said. Regan locked eyes with her mom for another second and then slipped the rest of the way out of the window.

Commander Fitz turned her attention to me, and I wished I could sink through the floor. “Sorry,” I said lamely, and hurried after Regan.

Regan waited for me to land beside her before taking off back toward the campus buildings.

“How many are there?” I asked, jerking my head toward the paper she still clutched in her hand.

“I don’t know,” she said, and her voice, so calm and steady mere seconds ago with her mom, now sounded strangled and choked. “Here, you look,” she said, thrusting it toward me. I took it from her, deciding not to comment on the tears that were streaming down her face. I glanced down at the map, but it was too dark to see anything, so I skidded to a stop at the next lantern we passed, grabbing Regan so she wouldn’t go charging off into the night without me. Considering we were out past curfew and every guard on campus was probably looking for us, the worst place we could possibly be was under a spotlight, but we didn’t have time for caution now, not when every second counted. I held the map up to the light and finished the job I’d started in the office before we’d been interrupted by Commander Fitz.

“There’s twenty-five,” I said. Somehow that number seemed simultaneously small and overwhelmingly large. When Regan first told me about her security-cameras-turned-explosives revelation, I’d pictured hundreds of cameras, a number so big even a fleet of people couldn’t retrieve them in time. Twenty-five was definitely better, but it was still terrifying to think about that many explosives sprinkled around campus.

“Twenty-five,” Regan repeated. “Salzburg wasn’t taking any chances, was he.”

“Should we have told your mom about him?” I asked, glancing back toward the house on the hill.

“And said what?” Regan asked. “All we have is a hunch, a hunch that would have taken entirely too long to explain. Besides, last I checked, nobody listened to criminals and their hunches.” I winced at the word criminal and Regan gave me a sympathetic smile and clapped me hard on the shoulder.

“If it makes you feel any better, there’s no one else I’d rather have as a partner in crime,” she said.

“In a weird way, that actually does make me feel better,” I said. Regan glanced behind her to where the Edison clock tower was illuminated.

“We have exactly forty minutes left to find them all,” she said. “We need to get moving.”
