"s", and "z". The other Johns had been unable to handle them, too.

"Hungrih, Neff. Hungrih!"

The big man picked out three grains of wheat. He noticed the can was almost empty. One by one he handed the kernels to his pet, waiting for John's "Tinkoo!" in between.

"Mur! Mur!"

"Lazy tongue! It's more, not mur!"

John dropped to all fours and retreated. Usually Neff slapped him in the belly when he used that tone. But Neff was bemused tonight. He kept listening for sounds, sounds that he knew could never penetrate the thick walls.

They were out there, he was sure. Another damned fool or two, flashing a light around, trying to figure out something. Neff remembered one pair who had even tried nitroglycerin. He saw the burns on the outside of the door the next morning.

Amateurs! Nobody knew for sure just how much money Neff kept in the old desk, and big-time pros wouldn't tackle a job like this without a pretty fair notion of the loot. For all they knew, maybe he mailed it to an out-of-town bank.

"Okay, fetch the pencil."

John jumped from the desk and moved toward the open door of the shower-stall where Neff had thrown the pencil stub. He paused by the wheat can, then scurried on to get the pencil. He climbed Neff's leg and dropped the pencil into the open palm.

"Smart punks up at State College. So you can't teach a rat anything but mazes and how to go nuts from electric shocks, eh? Wouldn't they be surprised to meet you, John?"

"Hungrih!"

"You're always hungry!"

"Meat! Meat!"

"Yeah. You can sound your "e's" real good when you say, 'meat.' Some day I'll cut off your tail and feed it to you." He laughed, grabbed John by the coarse hair of his back and slipped him back under the cage.

Then he undressed down to his underwear, turned out the light and lay on the narrow iron bed. John rustled in his cage for a minute, then there was only the faint hum of the blower and sucker motors in the ventilating system. The incoming and outgoing air was baffled and trapped to kill sounds, and spring-loaded sliding doors poised to jam shut and seal off the room if anyone tampered with the exterior grilles in the roof.

The fans hummed softly and Erd Neff slept.

Sleck-thud, sleck-thud!

e was awake pawing the wall for the light switch, but even as his hand found it, and his eyes discovered the closed ventilator doors, a reddish vapor sank over his body. A single gasp and Neff was clawing his throat. Sharp, brown-tasting, acid-burning, eye-searing, nose-stinging!

He fell to his knees and clawed to the far corner, fighting for air, but the acrid stink stained his throat and nose. His eyes kept burning. The whole room must be full!

The door-lever! No, that's what they wanted. Blind! Gun's no good now. God, for a breath of air! Damned tears! Can't open my eyes! Air! Got to have it!

His throat refused to open. The stink, a little like iodine, a lot like a hospital smell but a million times stronger—raked at the tender tissues of his throat. Icepicks stabbed from his soft palate, up into his brain, his temples. He swayed against the door, caught the lever and heaved convulsively. The door fell away slowly. He stumbled forward, gashing his knee against the sharp jamb.

A light struck redly through his clenched, tear-soaked eye-lids.

"That did it. Get the gun!" The voice was high, almost girlish. A young boy?

A slightly heavier voice said, "Got it. Keep an eye on him while I find out why the fan stopped working."

"He's going no place. You were right. That bromine stuff really did the business. Lookit his face. Sure it won't kill him?"

"Don't care if it does now. We got the door open."

"What is this bromine, anyhow? Boy it sure stinks!"

"It's a chemical element like
