I turned the small silver tactical unit pin around between my thumb and index finger and weighed whether to put the bag in the overhead bin or keep it close to my feet.

I pushed the canvas bag with the small silver pin all the way under seat two B, back into the shadows.

I sat down on the cold leather seat.

The heavy brass buckle clinked as I fastened my own belt.

A shadow fell over my shoulder.

Harrison Caldwell had stopped in the aisle right beside row two.

He carried his suit jacket draped over his left arm, and his heavy silver watch caught the cabin lights overhead.

David Ross stopped right behind him.
