The shorter one started to run. Mesner shot him in the back of the
head. The tall man grabbed up a piece of iron with a hooked end and
started yelling as he ran toward us.
"Open the briefcase," Mesner said calmly.
I opened it. Mesner leaned the rifle against a tree. He knelt down,
brought a metal disc out of the briefcase attached to a wire. He turned
a dial on a bank of controls inside the case. I heard a whirring hum.
The tall hillbilly screamed. He stretched up on his toes, strained his
arms and neck at the sky, then fell twitching on his face.
Mesner walked toward the hillbilly and I stumbled after him. I was
going to be sick, very sick. The sun worked like pins in my eyeballs.
Mesner drew a round metal cap which he called a stroboscope from the
case, fitted it on the hillbilly's head. The metal strip had a disc
hanging down in front of the hillbilly's eyes and about two inches away.
Mesner worked the dials and the flicker began blinking off and on,
faster and faster, then slower, then faster again as the hillbilly's
eyes stared into it unblinkingly. His muscles began to twitch. He beat
the ground with his flat hands. Grasshoppers jumped across his face.
Mesner pointed out to me that I was watching an on-the-spot
brain-probe. The brain-prober, or bipper, as Mesner called it, was so
effective he hardly ever had to use the other items in the case such
as the psychopharmaceuticals, drugs, brain shock gadgets, extractors,
nerve stretchers and the like.
Mesner sat on his haunches, worked the flicker and lit a cigarette.
"These brain-wave flickers correspond to any desired brain-wave rhythm.
You play around and you'll get the one you want. They talk. What they
don't say comes out later from the recorder. With this bipper you can
get anything out of anyone, almost. If you don't get the info you want
it's only because they don't have it. It burns them out considerably in
the process, but that's all to the good. They're erased, and won't do
any meddlesome thinking again."
The hillbilly wasn't moving now as the flicker worked on his eyes and
activated desired mental responses.
"Dirkson," Mesner said. "What happened to your sister, Elsa?"
"Don't know. She runned away."
"She was blind wasn't she? Wasn't she born blind?"
