Keltham will read a few pages for real, then (tell Fennelosa to) flip through pages starting from whatever they showed him, leaving each page spread to be scryed only for four seconds or so for Keltham to skim-speedread. (He once wrote a computer program as a kid to help him learn to move his eyes faster, and was disgruntled to learn that when he followed the shifting blue word as fast as he could, he couldn't understand what he'd read. Nonetheless, Keltham can skim pretty darn quickly if he wants to, and can still notice anomalies at that speed.)
Keltham will read about a hundred pages that way... they do all seem to be there...
Wait.
Shit.
He thought about that before he did it.
