looked at the empty space where a three-story stone house seventy-five years old had stood the night before.
âWhy, it isnât there,â said Alice feebly from the upper window. âIt ⦠isnât ⦠there.â
âThen Iâm not insane.â Thorne stumbled toward them. Ellery watched the old manâs feet sloughing through the snow, leaving long tracks. A manâs weight still counted for something in the universe, then. Yes, and there was his own shadow; so material objects still cast shadows. Absurdly, the discovery brought a certain faint relief.
âIt is gone!â said Thorne in a cracked voice.
âApparently.â Ellery found his own voice thick and slow; he watched the words curl out on the air and become nothing. âApparently, Thorne.â It was all he could find to say.
Dr. Reinach arched his fat neck, his wattles quivering like a gobblerâs. âIncredible. Incredible!â
âIncredible,â said Thorne in a whisper.
âUnscientific. It canât be. Iâm a man of sense. Of senses. My mind is clear. Things like thisâdamn it, they just donât happen!â
âAs the man said who saw a giraffe for the first time,â sighed Ellery. âAnd yet ⦠there it was.â
Thorne began wandering helplessly about in a circle. Alice stared, bewitched into stone, from the upper window. And Keith cursed and began to run across the snow-covered driveway toward the invisible house, his hands outstretched before him like a blind manâs.
âHold on,â said Ellery. âStop where you are.â
The giant halted, scowling. âWhat dâye want?â
Ellery slipped his revolver back into his pocket and sloshed through the snow to pause beside the young man in the driveway. âI donât know precisely. Somethingâs wrong. Somethingâs out of kilter either with us or with the world. It isnât the world as we know it. Itâs almost ⦠almost a matter of transposed dimensions. Do you suppose the solar system has slipped out of its niche in the universe and gone stark crazy in the uncharted depths of space-time? I suppose Iâm talking nonsense.â
âYou know best,â shouted Keith. âIâm not going to let this screwy business stampede me . There was a solid house on that plot last night, by God, and nobody can convince me it still isnât there. Not even my own eyes. Weâveâweâve been hypnotized! The hippo could do it hereâhe could do anything. Hypnotized. You hypnotized us, Reinach!â
The doctor mumbled: âWhat?â and kept glaring at the empty lot.
âI tell you itâs there!â cried Keith angrily.
Ellery sighed and dropped to his knees in the snow; he began to brush aside the white, soft blanket with chilled palms. When he had laid the ground bare, he saw wet gravel and a rut.
âThis is the driveway, isnât it?â he asked without looking up.
âThe driveway,â snarled Keith, âor the road to hell. Youâre as mixed up as we are. Sure itâs the driveway! Canât you see the garage? Why shouldnât it be the driveway?â
âI donât know.â Ellery got to his feet, frowning. âI donât know anything. Iâm beginning to learn all over again. Maybeâmaybe itâs a matter of gravitation. Maybe weâll all fly into space any minute now.â
Thorne groaned: âMy God.â
âAll I can be sure of is that something very strange happened last night.â
âI tell you,â growled Keith, âitâs an optical illusion!â
âSomething strange.â The fat man stirred. âYes, decidedly. What an inadequate word! A house has disappeared. Something strange.â He began to chuckle in a choking, mirthless way.
âOh that,â said Ellery impatiently. âCertainly. Certainly, Doctor. Thatâs a fact . As for you, Keith,
