The glass towers of the loop stretched up into the low, gray clouds.

Blake pulled into an underground parking garage beneath a massive steel skyscraper.

He bypassed the main elevators and led us to a private service elevator at the back of the garage.

The boys clustered around Clara, their eyes heavy with sleep but bright with anxiety.

“Are we safe here, Mom?” Toby asked, pulling at the sleeve of my coat.

“Yes, Toby,” I said, kissing the top of his head. “We are safe.”

The elevator doors slid open on the forty-second floor, revealing a quiet, carpeted lobby.

Blake unlocked a heavy mahogany door that led to his private suite.

The office was vast, with floor-to-ceiling windows overlooking the dark waters of Lake Michigan.

“Sit down,” Blake said, pointing the boys toward a large leather sofa.

Clara sat with them, wrapping her arms around Sam’s shoulders.

Blake went to his desk and opened a small wooden panel in the wall.

He entered a code on a digital keypad, and a heavy steel safe swung open.

He pulled out a thick blue folder and a black USB drive.
