The Street That Wasn't There by Clifford D. Simak, Science Fiction, Fantasy, Adventure (Paperback) (ISBN-13: 9781606644287)

SOMETHING WAS WRONG WITH THE WORLD!

The pendulum clock struck slowly, its every other chime as usual setting up a sympathetic vibration in the pewter vase that stood upon the mantel. Mr. Chambers got to his feet, strode to the door, opened it and looked out. Moonlight tessellated the street in black and silver, etching the chimneys and trees against a silvered sky. But the house directly across the street was not the same. It was strangely lopsided, its dimensions out of proportion, like a house that suddenly had gone mad. He stared at it in amazement, trying to determine what was wrong with it. He recalled how it had always stood, foursquare, a solid piece of mid-Victorian architecture. Then, before his eyes, the house righted itself again. With a sigh of relief, Mr. Chambers turned back into the hall. But before he closed the door, he looked again. The house was lopsided -- worse than before!
