He looked at her peculiarly. "Ever think what might happen if someone started a black market in neutroids?"

They finished the meal in silence. After lunch he went out again to gather up the rest of the group. By four o'clock, he had gotten all that were to be had without the threat of a warrant. The screams and pleas and tears of the owners left him gloomily despising himself.

If Delmont's falsification had been widespread, he might have to turn several of the thirty-five over to central lab for dissection and ultimate destruction. That would bring the murderous wrath of their owners down upon him. He began to understand why bio-inspectors were frequently shifted from one territory to another.

On the way home, he stopped in Sherman II to check on the missing number. It was the largest of the Sherman communities, covering fifty blocks of commercial buildings. He parked in the outskirts and took a sidewalk escalator toward O'Reilley's address.

It was on a dingy sidestreet, reminiscent of past centuries, a street of small bars and bowling alleys and cigar stores. There was even a shop with three gold balls above the entrance, but the place was now an antique store. A light mist was falling when he stepped off the escalator and stood in front of the pet shop. A sign hung out over the sidewalk, announcing:

J. "DOGGY" O'REILLEY
PETS FOR SALE
DUMB BLONDES AND GOLDFISH
MUTANTS FOR THE CHILDLESS
BUY A BUNDLE OF JOY

Norris frowned at the sign and wandered inside. The place was warm and gloomy. He wrinkled his nose at the strong musk of animal odors. O'Reilley's was not a shining example of cleanliness.

Somewhere a puppy was yapping, and a parrot croaked the lyrics of A Chimp to Call My Own, which Norris recognized as the theme song of a popular soap-opera about a lady evolvotron operator.

He paused briefly by a tank of silk-draped goldfish. The shop had a customer. An elderly lady was haggling with a wizened manager over the price of a half grown second-hand dog-F. She was shaking her last dog's death certificate under his nose and demanding a guarantee of the dog's alleged F-5 intelligence. The old man offered to swear on a Bible, but he demurred when it came to swearing on a ledger.

The dog was saying, "Don' sell me, Dada. Don' sell me."
