“You take care of it all,” he told the man.

“Yes, sir,” the man said. “I usually do.”

The rest of the day, Collins reclined on a couch and drank iced beverages while the Maxima Olph Construction Company materialised equipment and put up his house.

It was a low-slung affair of some twenty rooms, which Collins considered quite modest under the circumstances. It was built only of the best materials, from a design of Mig of Degma, interior by Towige, a Mula swimming pool and formal gardens by Vierien.

By evening, it was completed, and the small army of workmen packed up their equipment and vanished.

Collins allowed his chef to prepare a light supper for him. Afterward, he sat in his large, cool living-room to think the whole thing over. In front of him, humming gently, sat the Utilizer.

Collins lighted a cheroot and sniffed the aroma. First of all, he rejected any supernatural explanations. There were no demons or devils involved in this. His house had been built by ordinary human beings, who swore and laughed and cursed like human beings. The Utilizer was simply a scientific gadget, which worked on principles he didn’t understand or care to understand.

Could it have come from another planet? Not likely. They wouldn’t have learned English just for him.

The Utilizer must have come from the Earth’s future. But how?

Collins leaned back and puffed his cheroot. Accidents will happen, he reminded himself. Why couldn’t the Utilizer have just slipped into the past? After all, it could create something from nothing, and that was much more complicated.
