“You better move back a ways,” Hezekiah warned Homer. “He's simply dripping fleas.” .. .

“It’s not a flea,” said Archie, puffing up in anger.. “It is something else. I caught it this afternoon. It ticks and it looks like an ant, but it isn’t one.” The thing that ticked oozed between Archie’s claws and tumbled to the floor. It landed right side up and was off again. Archie made a stab at it, but it zig-zagged but of reach. Like a flash it reached Hezekiah [the robot] and streaked up his leg.

Homer [the dog] came to his feet in a sudden flash of knowledge.

“Quick!” he shouted. “Get it! Catch it! Don’t let it. ..”

But the thing was gone.

Slowly Homer sat down again. His voice was quiet now, quiet and almost deadly.

“Wardens,” he said, “take Hezekiah into custody. Don’t leave his side, don’t let him get away. Report to me everything he does...

“It won’t be easy;” Homer said. “Not even for a webster. Those ants are smart. Archie told you about the flea he found.”

“It wasn’t any flea,” said Archie. “Yes, he told me,” Jenkins said. “Said it got onto Hezekiah.”

“Not onto,” Homer told them. “Into is the word, it wasn’t a flea... it was a robot, a tiny robot. It drilled a hole in Hezekiah’s skuli and got into his brain. It sealed the hole behind it.”

“And what is Hezekiah doing now?”

“Nothing,” said. Homer. “But we are pretty sure what he will do as soon as the ant robot gets the setup fixed. He’ll get the Call. He’ll get the call to go and work oh the Building.”
