“As the man said who saw a giraffe for the first time,” sighed Ellery. “And yet... there it was.”

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 man’s.

“Hold on,” said Ellery. “Stop where you are.”

The giant halted, scowling. “What d’ye want?”

Ellery slipped his revolver back into his pocket and sloshed through the snow to pause beside the young man in the driveway. “I don’t know precisely. Something’s wrong. Something’s out of kilter either with us or with the world. It isn’t the world as we know it. It’s 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 I’m talking nonsense.”

“You know best,” shouted Keith. “I’m 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 isn’t there. Not even my own eyes. We’ve — we’ve been hypnotized! The hippo could do it here — he could do anything. Hypnotized. You hypnotized us, Reinach!”

The doctor mumbled: “What?” and kept glaring at the empty lot.

“I tell you it’s there!” 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. “This is the driveway, isn’t it?” he asked without looking up.

“The driveway,” snarled Keith, “or the road to hell. You’re as mixed up as we are. Sure it’s the driveway! Can’t you see the garage? Why shouldn’t it be the driveway?”
