The dog stirred. He thumped around hastily, backing out of the shed. "My goodness." Embarrassed, he made his way quickly to the fence. Standing up on his hind paws, he opened his mouth wide. "Woof!" he summoned. He glanced apologetically at the Clerk. "I beg your pardon. I can't understand how — "

The Clerk gazed fixedly down at his watch. Cold terror knotted his stomach. The hands showed eight-sixteen. "You failed," he grated. "You failed! You miserable flea-bitten ragbag of a wornout old mutt! You failed!"

The dog dropped and came anxiously back. "I failed, you say? You mean the summons time was — ?"

"You summoned too late." The Clerk put his watch away slowly, a glazed expression on his face. "You summoned too late. We won't get A Friend with a Car. There's no telling what will come instead. I'm afraid to see what eight-sixteen brings."

"I hope he'll be in Sector T137 in time."

"He won't," the Clerk wailed. "He won't be there. We've made a mistake. We've made things go wrong!"

Ed was rinsing the shaving cream from his face when the muffled sound of the dog's bark echoed through the silent house.

"Damn," Ed muttered. "Wake up the whole block." He dried his face, listening. Was somebody coming?

A vibration. Then —

The doorbell rang.
