Milgrim lay the Neo on the Kleenex, resting it in the valley between his knees, opened the other two sheets, and began to carefully polish it. When he was finished, he remembered having idly removed the back, on the flight to Atlanta.

When he’d finished rubbing down the outside, he carefully folded the first tissue around it and slipped it into his pocket. He crumpled the other two and wiped his palms with them.
