Back to the face came the clarity of outline, and still it was Professor Ramsey Burr's body she stared at.

Her son, in the professor's shape, climbed from the platform, and looked about him as though dazed. An acrid smoke filled the room, and burning insulation assailed the nostrils.

Desperately, without looking at her, his lips set in a determined line, the man went hurriedly over the apparatus again.

"Have I forgotten, did I do anything wrong?" she heard his anguished cry.

Two tubes were burned out, and these he replaced as swiftly as possible. But he was forced to go all over the wiring, and cut out whatever had been short-circuited so that it could be hooked up anew with uninjured wire.

Before he was ready to resume his seat on the platform, after half an hour of feverish haste, a knock came on the door.

The person outside was imperative, and Mrs. Baker ran over and opened the portal. Jared, the whites of his eyes shining in the dim light, stood there. "De professah—tell him dat de wahden wishes to talk with him. It is very important, ma'am."

The body of Burr, inhabited by Allen's soul, pushed by her, and she followed falteringly, wringing her hands. She saw the tall figure snatch at the receiver and listen.

"Oh, God," he cried.

At last, he put the receiver back on the hook, automatically, and sank down in a chair, his face in his hands.
