Jenna Holloway came down the carpeted aisle, holding a black tablet tightly against her chest with both hands.

“I told Mrs.

Carter I’d deleted my original photo, but I had emailed the image file to my personal address that same night.”

She passed the tablet to the administrative clerk, showing the high-resolution picture she had taken at five thirty that morning.

The digital image matched the paper document word for word and time for time, and it carried the original electronic metadata from October fourteenth.
