“Not now,” the blind man said. “The road is too plain. Today, when Tucker searched the house, he found the cover of the August Miracle World and a fragmentary scrap torn from a magazine page. Only ten words were on that scrap, Fred, but one of them was ‘sonority.’ It’s a word dealing with sound. On a bare chance I dropped in at the public library. There I learned that one Frederick Wingate is a subscriber to Miracle World, and each month turns the magazine over to the library after he has read it. But this Mr. Wingate did not turn over his August copy; the library, wishing to keep a complete file, sent for the August number. There was a significant article in that number, Fred. The librarian read it to me. It had to do with sound effects by radio and telephone.”

Joe’s lips were parted breathlessly. Frederick Wingate stood as though he had lost the power of movement.

“I’m not up on those things. They developed after I became blind. Exactly how you worked the trick I do not know. After reading the August number you concocted your scheme. You took your time. But in December you got the key from Rhodes on the pretext you wanted to paint in the house and try out the light. In that month you did your wiring, broke through walls, inserted your loud speakers and tuned them to the proper pitch. The transmitting cable from your house to Farley’s was probably laid on the ground under the snow. No doubt you thought you would not have to give more than five or six manifestations. Let the ghost talk start. After that you could take up the cable. The thing would be done. Farley’s property would be ruined; you’d buy it in for a song.

“What did you do from December to March? Practice the act? Anyway, you ran into the unexpected. Sweetman also saw a chance to buy cheaply. So you filled him with the fear of inheriting a ghost. Then, when the road seemed clear, Tucker came in. You hadn’t expected the police. Today, when you protested to Tucker, Rodgers thought you were furiously indignant. I read your voice better. You were alarmed. So tonight, as soon as darkness fell, you took up the incriminating cable. You’re wealthy. Why does a man of means stoop to small cupidities? Is it because he thinks it clever and smart?”

The artist spoke hoarsely. “You’ll admit, Doctor, that this is all rather circumstantial?”

“It was until a little while ago. Then I found the absolute proof. Sometimes a thing becomes so much a part of a man that he forgets he has it and it betrays him. Do you mind telling me the time?”

The artist glanced at his wrist-watch. “It is now——” His eyes, startled, stared fixedly at the doctor. “I see,” he said.

Dr. Stone relighted the pipe. “Might I make a suggestion. We don’t want Tucker in on this. I’m more interested in Matt Farley. My suggestion is that you buy the place even below its worth, eight thousand dollars. Eight thousand will be a fortune to a man sick and penniless.”

Wet blotches fell against the windows. Snow!

“Doctor,” Frederick Wingate said, “will you believe me when I say I did not know Farley was destitute?” He picked his coat from a chair. “I’ll see Rodgers in the morning and put down a deposit. Good night.”
