Barter sat down under the light marked "B-2" and lifted the key which dangled from the end of the golden chain. This key he inserted in a tiny orifice in the ball atop his head. Then he turned in his chair to look at Lecky. Barter's face was a mask of concentration as he gazed intently at the young man.

Lecky stiffened to attention. His right hand shot to his cap visor in salute. His lips twisted into a travesty of a smile. For a few seconds he went through a strange series of posturings. He stood in the att.i.tude of a boxer preparing to attack. He danced smartly on his toes. He bent double and touched the floor with the palms of his hands. He jumped up and down with his legs stiff. He stopped suddenly with his right hand at rigid salute. But his eyes were still vacant through every posture.

Barter's face showed a glow of satisfaction.

"He did exactly what I willed him to do! I am his master. He is my slave--even more abjectly than you are my slave, Naka Machi!"

"But that would be impossible, my master," said Naka Machi, hissing again through his teeth as he sucked in his breath. "None could be more abjectly your slave than I."

"Do not say anything is impossible," said Barter peevishly, "when I say otherwise. Anything is possible to me! Now, we'll send Lecky forth. I'll watch him through the heliotubes and control his every move. While I am directing Lecky you will prepare the table behind me for the first of our world-revolutionizing operations."

"Yes, my master," said the j.a.panese humbly.

"But first, it's just as well that Lecky is in a good humor, even though he is my slave. Where are the walnuts, Naka Machi?"

The j.a.panese tendered a large walnut to Barter. Barter rose and approached Lecky who still stood at salute. He stopped a couple of paces in front of the soldierly man and held up the walnut as a man sometimes holds up food to a dog, bidding him "speak" before he may be fed.

Then Lecky did a strange thing.

He began to jump up and down like a pleased child. His jumping caused him to lose his balance, but he recaptured it by pressing the backs of his hands against the floor. His. .h.i.therto expressionless eyes lost their dullness. Saliva dribbled at the corners of his mouth. Barter tossed him the walnut. Lecky held it under his right forefinger, against the _heel_ of his thumb, instead of between thumb and forefinger, as he lifted it to his mouth.

Barter chuckled.

"Even the human cas.e.m.e.nt cannot wholly hide the ape, eh, Naka Machi?"

said Barter.

Naka Machi hissed.

Barter returned to the porcelain slab banked with the lights and the keys. He readjusted the keys and his face became thoughtful again.

Lecky turned smartly, still nibbling at his walnut, strode to the bronze door and let himself out.

Through the heliotube directly above the key marked "B-2," Caleb Barter watched him go, and kept watching him as he made his way to the street. Barter looked ahead of his puppet, noting the cars which were parked at the curb. He saw a stately limousine. He grinned. The chauffeur was not in sight. Barter looked for him and found him at a table in a nearby restaurant, his back to the window.

Barter looked back at his puppet and his face became serious with concentration.

Lecky walked blithely along the street and turned right when he was opposite the limousine. Without a moment's hesitation, he stepped into the limousine, pressed the starter, shifted gears, turned in the middle of the block and started swiftly uptown.

After Lecky had shifted gears he drove with his left hand alone. His right was still busy with the walnut.

Barter now looked like a man in a trance, so deeply did he concentrate on his task of guiding his soulless, ape-brained puppet, Lecky, through the heavy traffic of Manhattan.

CHAPTER IV

_The Opening Gun_

"That list, Tyler," said Bentley, after he had somewhat calmed the fears of Ellen Estabrook and had returned to the task of tracing Barter, "is headed by Harold Hervey, the multi-millionaire. I know Barter well enough to know that he'll go down the list methodically, taking each person in turn. We'd best take immediate precautions to guard the old man's home. For Barter, if not entirely ready to take drastic steps, must be almost ready, else he couldn't issue his manifestoes and take a chance of some slip-up before he could get really started."

"Why do you suppose he named Hervey on the list?" asked Tyler.

"Because Hervey is a financial genius. Barter wishes not only to carry out his plan of creating a race of supermen, but wishes at the same time to maintain personal control of them. And to control Manhattan, from which he logically hopes to extend his control to the whole United States, then to the whole world, Barter must also control the money marts. Hervey is the shrewdest financier in the world."

"But won't we frighten Hervey's family if we take steps now?"

"Better to frighten them now than to be too late entirely. However, we can place his house under surveillance without the knowledge of the family for the time being. And you'd better send a couple of men to his office in the Empire State Building to see that nothing happens to him on the way home this evening. I talked to him by telephone and he pooh-poohed the whole thing. Hard-headed business executives have no imagination."

Bentley and Tyler rode uptown in the back seat of a speeding police car driven by one of the best chauffeurs Bentley had ever ridden behind. He edged through holes in the traffic where Bentley could scarcely see any holes at all. He estimated the speed of cars which might have collided with the police vehicle and slipped through with inches to spare. In his way the man was a genius. But Bentley was yet to see the driving of a master genius....

Far out in the residential district the police car came to a stop. Other police cars arrived at intervals to disgorge men in plain clothes who immediately entered upon their guard duties as un.o.btrusively as possible. If Hervey's family noticed at all they would scarcely attach any importance to the arrival of cars and the discharging of pa.s.sengers who seemed to have nothing to do except dawdle on the sidewalks.

But all the way uptown a hunch had ridden Bentley. He had the feeling that no matter how fast the police car traveled, no matter how skilfully the chauffeur inched his way through the press, they would be too late to save Hervey. The feeling became an obsession. Many times he called through the speaking tube.

"Faster, driver, for G.o.d's sake, faster!"

Now near the home of Harold Hervey, Bentley found himself unable to walk slowly, with the air of nonchalance, which the other police officers wore like a cloak.

"Something's happened," said Bentley, "I'm sure of it. I feel that Barter is so close to me that I could touch him if I knew in which direction to extend my fingers."

Suddenly a speeding car, with horn bellowing, came crashing up the street toward the Hervey residence. It was traveling at great speed, careening from side to side like a ship in a storm at sea.

"There comes Hervey's car," said Tyler. "And something has happened to make him travel like that. Old man Hervey doesn't allow his chauffeur to go faster than twenty miles an hour."

Tyler and Bentley were near by when the car squealed to a stop before the Hervey residence and a hatless, disheveled man leaped out almost before the car stopped rolling.

"That's not Hervey," said Tyler. "That's his private secretary.

Something's up. It's time we took a hand in things."

Tyler and Bentley grasped the young man by the elbow.

"What's up?" demanded Tyler.

"It's Mr. Hervey, sir," panted the secretary. "It just happened. He's been kidnaped!"

The secretary was a slight man, but fear had given him strength. He almost dragged Tyler and Bentley off their feet as he strode on up the walk leading to the home of Hervey.

"You'll scare his family half to death!" said Tyler.
