“They bypassed the alarm,” Daniel said, checking his wrist monitor. “The wires were cut from the outside.”

“How did they get through the pressure sensors on the lawn?” I asked.

I looked at Caleb, whose smile had faded into a cold stare.

“Caleb gave them the map,” I said. “He gave them the blind spots.”

“I gave them everything, Adrian,” Caleb said softly.

Marcus raised his hand to strike him, but I caught his wrist.

“Don’t,” I said. “We don’t have time.”

The air in the cellar felt heavier now, smelling of old dust and incoming rain.

I looked at the steel door we had just opened.

The green light on the bomb remained solid, but the wires still looked like a tangled nest of copper.

“Marcus,” I said, pointing to the metal box. “Can you lock this down permanently?”

Marcus stepped closer to the wall, his penlight shining on the exposed circuit board.

“The keycard stopped the timer,” Marcus said, squinting at the wires. “But if they cut the main line from the generator, the internal battery might trigger it again.”

“Why?” I asked.
