Doctor Spechaug turned his dark head. His companion apparently hadn't noticed anything ominous or peculiar. But to him, the whole scene was morose, fetid and brooding.

They walked down the cracked concrete walk, passed the big plate-glass windows of Murphy's General Store which were a kind of fetish in Glen Oaks. But Doctor Spechaug wasn't concerned with the cultural significance of the windows. He was concerned with not looking into it.

And oddly, he never did look at himself in the glass, neither did he look across the street. Though the glass did pull his gaze into it with an implacable somewhat terrible insistence. And he stared. He stared at that portion of the glass which was supposed to reflect Edith Bailey's material self—but didn't reflect anything. Not even a shadow.

They stopped. They turned slowly toward each other. He swallowed hard, trembled slightly. And then he knew deep and dismal horror. He studied that section of glass where her image was supposed to be. It still wasn't.

He turned. And she was still standing there. "Well?"

And then she said in a hoarse whisper: "Your reflection—where is it?"

And all he could say was: "And yours?"

Little bits of chuckling laughter echoed in the inchoate madness of his suddenly whirling brain. Echoing years of lecture on—cause and effect, logic. Little bits of chuckling laughter. He grabbed her arm.

She shivered. Her face was terribly white. "What—what is the answer?"
