the last words with blows on the table.
Northwood laughed dryly. "How many thousands of years are you looking forward, Professor?"
The professor made an obscure noise that sounded like a smothered sniff. "You and I shall never agree on the point that mental advancement may wipe out physical limitations in the human race, perhaps in a few hundred years. It seems as though your profound admiration for Dr. Mundson would win you over to this pet theory."
"But what sane man can believe that even perfectly developed beings, through mental control, could overcome Nature's fixed laws?"
"We don't know! We don't know!" The professor slapped the magazine with an emphatic hand. "Emil Mundson hasn't written this article for nothing. He's paving the way for some announcement that will startle the scientific world. I know him. In the same manner he gave out veiled hints of his various brilliant discoveries and inventions long before he offered them to the world."
"But Dr. Mundson is an electrical wizard. He would not be delving seriously into the mysteries of evolution, would he?"
"Why not?" The professor's wizened face screwed up wisely. "A year ago, when he was back from one of those mysterious long excursions he takes in that weirdly different aircraft of his, about which he is so secretive, he told me that he was conducting experiments to prove his belief that the human brain generates electric current, and that the electrical impulses in the brain set up radioactive waves that some day, among other miracles, will make thought communication possible. Perfect man, he says, will perform mental feats which will give him complete mental domination over the physical."
NORTHWOOD finished reading and turned thoughtfully to the window. His profile in repose had the straight-nosed, full-lipped perfection of a Greek coin. Old, wizened Professor Michael, gazing at him covertly, smothered a sigh.
"I wish you knew. Dr. Mundson!" he said. "He, the ugliest man in the world, delights in physical perfection. He would revel in your splendid body and brilliant mind."
Northwood blushed hotly. "You'll have to arrange a meeting between us."
"I have." The professor's thin, dry lips pursed comically. "He'll drop in to see you within a few days."
And now John Northwood sat holding Dr. Mundson's card and the wallet which the scientist had so mysteriously dropped at his feet.
HERE was high adventure, perhaps, for which he had been singled out by the famous electrical wizard. While excitement mounted in his blood, Northwood again examined the photograph. The girl's strange eyes, odd in expression rather than in size or shape, seemed to hold him. The young man's breath came quicker.
"It's a challenge," he said softly. "It won't hurt to see what it's all about."
His watch showed eleven o'clock. He would return the wallet that night. Into his coat pocket he slipped a revolver. One sometimes needed weapons in Indian Court.
He took a taxi, which soon turned from the well-lighted streets into a section where squalid houses crowded against each other, and dirty children swarmed in the streets in their last games of the day.
Indian Court was little more than an alley, dark and evil smelling.
The chauffeur stopped at the entrance and said:
"If I drive in, I'll have to back out, sir. Number forty-four and a half is the end house, facing the entrance."
"You've been here before?" asked Northwood.
"Last week I drove the queerest bird here—a fellow as good-looking as you, who had me follow the taxi occupied
