“He’s lying,” Marcus muttered from the doorway.

“I’m not,” Caleb said. “I left it somewhere you’ll never think to look.”

My mind raced through the acres of the estate.

“The greenhouse?” I asked.

Caleb kept his eyes locked on mine, his expression blank.

“The library?” I tried again.

A tiny twitch in his left eyelid gave him away.

“It’s in the library,” I said.

“You’re guessing,” Caleb said, but his voice had lost its edge.

“Daniel, keep searching him,” I ordered. “Marcus, come with me.”

We ran back up the stone steps.

The cold air of the foyer felt like a physical blow.

The grandfather clock was still ticking, a steady, mocking rhythm.

“Where in the library would he hide a keycard?” Marcus asked.

“Somewhere secure,” I said. “Somewhere he had access to daily.”

We entered the library, the smell of old leather and paper surrounding us.

I walked to the massive mahogany desk.

I pulled open the drawers, dumping their contents onto the floor.

Pens, paperclips, old ledgers, and keys scattered across the rug.

Nothing with a biometric sensor.

“Check the bookshelves,” I said.
