Everything needs batteries, Milgrim thought. Even whatever spooky little unit Brown’s cohort was using to grab the IF’s texting, what little there was of it, both incoming and outgoing, out of the air in this room. Milgrim was curious about that, because as far as he knew it shouldn’t be possible, not without actually having a bug in the IF’s phone. And this IF, Brown had said, seldom used the same phone, or account, twice. He bought them and tossed them on a regular basis—which was no more than Birdwell did, now he thought about it.
