ul of her son within that form. The eyes were Allen's, the voice
was soft and loving, and his spirit was with her.

"Come, Allen, my son," she said softly.

"Burr paid the price," said Allen, shaking his head. "He became a martyr
to science."

The world has wondered why Professor Ramsey Burr, so much in the
headlines as a great scientist, suddenly gave up all his experiments and
took up the practice of medicine.

Now that the public furor and indignation over the death of the man
Smith has died down, sentimentalists believe that Ramsey Burr has
reformed and changed his icy nature, for he manifests great affection
and care for Mrs. Mary Baker, the mother of the electrocuted man who had
been his assistant.

"There's no hurry, Doctor," replied Operative Carnes of the United
States Secret Service as he entered the room and sat on the edge of the
Doctor's desk. "I haven't got a case up my sleeve this time; I just came
in for a little chat."

"All right, glad to see you. Read that latest volume of the
