"Surely."
"I would not have believed you had you said otherwise," replied the Russian with a sigh. "Yet this device has done much good. Now it shall be destroyed. It has not been a failure, for its destruction will accomplish both yours and that of your friend, Carnes."
"You haven't caught Carnes yet."
"That is easy. The same bait which caught you has caught him even more easily. I have a real sense of humor, Doctor, and before I went out of my way to bring you here, my plans were carefully laid. Mr. Carnes is now on his way here from Washington, lured by my voice. He is rushing, he thinks, to your rescue."
"What--"
Dr. Bird was suddenly silent.
* * * * *
"I am glad you comprehend my plan so readily, Doctor. Yes, indeed, Mr. Carnes knows that I have captured you. He knows the exact location of this cavern and, more important, he knows the location of the power line which feeds my device when it is in operation. He also knows that there is stored in this cavern, fifty pounds of radite, your ultra-explosive. He knows that you are chained close to the explosive and that it is rigged with a detonator, connected with the power line. In only one thing is he in error.
"He thinks, that if he can sever the power line before he attempts to penetrate the cavern, that the charge will be rendered harmless, and that you will be safe. In point of fact, the charge is set with an interrupter detonator which will explode as soon at the power line is severed. It pleases my sense of humor that it will be the hand of your faithful friend, Carnes, that will send you in fragments to eternity."
Beads of sweat shone on Dr. Bird's head as the Russian finished his speech, but his expression of amused interest did not change. Neither did his voice, when he spoke, betray any nervousness.
"And I presume that Carnes is also to be blown into bits by the explosion?" he asked.
"No, indeed, Doctor, that would frustrate one of the most humorous angles of the whole affair. He will cut the line at the base of a large rock, some two hundred yards from here, far enough away that he will not be seriously injured by the force of the explosion. Thus he will witness the explosion and realize what he has done. In order to be sure that he knows, as soon as he cuts the wire, my men will capture him. I, personally, will tell him of it. I wish to see his face when he realizes what he has unwittingly done."
"Then, I presume, you'll kill him?"
"I doubt it. I rather think I'll let him live. He should be useful to me."
"Carnes will never work for you!"
"With Feodrovna in my power, I rather think that Mr. Carnes will be an efficient and loyal servant. If not, he shall have the pleasure of watching me wreak my vengeance on her before he, himself, takes his last long trip."
* * * * *
"Saranoff," said Dr. Bird in a level voice, his piercing eyes boring straight into the Russian's, "I will remember this. Later, when you grovel at my feet and beg for mercy, it will be my friend, Operative Carnes, who will read your doom to you and choose the manner of it. I can promise you that your death will not be an easy one."
The Russian laughed, albeit the laugh had more of uneasiness than humor in it.
"When you have me in your power, Doctor, you may do as you like," he said, "but I do not fear dead men. In another two hours, you will be among the dead."
He turned to the three Russians who stood behind him.
"Seize him!" he cried.
The Russians leaped forward, but Dr. Bird was not caught napping. The first one went down like a felled tree before the doctor's fist. The other two came in cautiously. Dr. Bird sprang forward, feinting. As he leaped back, his foot struck a rod which Ivan Saranoff had thrust behind him. He staggered and fell. Before he could recover his balance, the two burly Russians were on him.
Even then, they had no easy task. Dr. Bird weighed over two hundred and there was not an ounce of fat or surplus flesh on him. First one, and then the other, of the Russians was thrown off him, but they returned to the attack, unsubdued by the crashing blows which the doctor landed on their faces and heads.
Gradually their ardor began to evaporate. With a sudden effort, Dr. Bird strove to regain his feet. A crash as of all the thunders of the universe sounded in his ears, and flashes of vivid light played before his eyes. He felt himself falling down ... down....
* * * * *
He recovered consciousness to find his feet shackled and fastened to rings set in the concrete of the cavern wall. His head throbbed horribly. He raised his hands and found a huge bump on his head, from which thickened blood trickled sluggishly down his cheek. The cavern was flooded with light. On the wall before him, a clock told off the seconds with a metallic tick. He bent down and examined his shackles.
"I'm afraid you can't unfasten them, Doctor," said a sardonic voice.
He looked up to see Saranoff.
"I'm sorry I had to hit you so hard," went on the Russian. "Your half hour of unconsciousness has lessened by that much the time which is yours to indulge in an agony of apprehension. Look."
Dr. Bird's gaze followed the Russian's finger. On the floor, twenty feet from where he was shackled, stood a yellow can with the mark of the Bureau of Standards on its side. He recognized it at once as a radite container, a can of the terrible ultra-explosive which he himself had perfected. He shuddered at the thought of the havoc which its detonation would cause.
"Yes, Doctor, that is a can of radite," said the Russian. "Allow me also to call your attention to the interrupter fuse which is attached to it. When Mr. Carnes cuts the wire outside, you know well enough what will happen. Now, let me invite your attention to the clock on the wall before you. Mr. Carnes arrived at the Bush River station of the P. B. and W. at 2:15 A.M. He had a little trouble getting a boat, but he is now on his way here. It is 2:25. I think he will arrive between 3:30 and 4:00. Perhaps five minutes later, he will find the wire.
"You have a little over an hour in which to contemplate your total extinction, an extinction which will remove from my path the one great obstacle to my domination of the world. I hope you will enjoy your remaining moments. In order to help you to enjoy them, and to realize the futility of human endeavor, I have placed the key of your shackles on the floor here in plain sight, but, alas, out of your reach. I would like to stay and watch your struggle, to see the self-control on which you pride yourself vanish, and to watch you whimper and pray for the mercy you would not find; but I am deprived of that pleasure. I must take personal charge of my men to be sure that there is no slip. Good-by, Doctor, we will never meet again, I fear."
* * * * *
"We will meet again, Saranoff," said Dr. Bird in even tones of cold ferocity which made even Saranoff shiver. "We will meet again, and when you whimper and beg for mercy, remember this moment!"
The Russian started forward with an oath, his hand raised to strike. He recovered himself and essayed a sickly smile.
"I will remember, Doctor," he said in a voice which, despite himself, had a tremor of fear in it. "I will remember--when we meet again."
He ran lightly up the stairs and Dr. Bird heard the floor close above him. With a grunt, he bent down and examined his shackles closely. They were tight fitting and made of hardened steel. A cursory examination showed the doctor that he could neither force them nor slip them. He turned his attention to the key which Saranoff had pointed out. It lay on the floor, about ten feet, as nearly as he could judge, from where he stood.
He knelt and then stretched himself out at full length on the floor. By straining to the uttermost, his groping fingers were still six inches from the key. Saranoff had calculated the distance well.
Convinced that he could not reach the key by any effort of stretching, Dr. Bird wasted none of his precious time in vain regrets or in useless efforts to accomplish the impossible. He rose to his feet and calmly took stock of the room, searching for other means of freeing himself. The shackles themselves offered no hope. He searched his pockets. The search yielded a pocket knife, a bunch of keys
, a flashlight, a handkerchief, a handful of loose change, and a wallet. He examined the miscellany thoughtfully.
* * * * *
A light broke over his face. He tied one end of the handkerchief to the knife and again took a prone position on the floor. Cautiously he tossed the knife out before him. It fell to one side of the key. He drew it back and tried again. The knife fell beyond the key. Slowly he drew it back toward him by the handkerchief. When it reached his hand, he saw to his joy, that the key was a good inch nearer. With a lighter heart, he tried again.
His toss was good. The knife fell over the key, and again he drew it to him. To his disgust, the key had not moved. Again and again he tried it, but the knife slid over the key without moving it. He looked more carefully and saw that the key was caught on an obstruction in the flooring.
With careful aim, he threw his knife so as to drive the key further away. He threw the knife again and tried to draw the key to him from its new position. It came readily until it reached the inequality in the floor which had stopped it the first time. All of his efforts to draw it nearer were fruitless. He give vent to a muttered oath as he looked at the clock. Thirty minutes of his time had gone.
A second time he knocked the key away and strove to draw it to him with no success. The clock bore witness to the fact that another ten minutes had been wasted. He rose to his feet and carefully surveyed his surroundings.
A cry of joy burst from his lips. On the floor was a tiny metallic thread which he knew for a wire. He bent down and picked it up. It was fine and very flexible. He doubled it three times and strove to bend a hook in it. The wire was too short to offer much hope, but he threw himself prone and began to fish for the key.
The wire reached it readily enough, but it did not have rigidity enough to pull the key over the little bump which held it. A glance at the clock threw him into an agony of despair. A full hour had passed since Saranoff had left him. Carnes might even now be walking into the trap which had been laid for him.
He rose to his feet and thought rapidly, twisting the wire idly around the knife as he did so. He glanced at the work of his hands, and an oath broke from his lip.
"Fool!" he exclaimed. "I deserve to die! The means for liberation were in my hands all the time."
* * * * *
With feverish activity, he ripped open the flashlight. He held the two ends of the wire against the terminals of the light battery and touched the knife to his steel key ring. To his joy, the ring adhered to the knife. Under the influence of the battery, the wire-wrapped knife had become a small electromagnet.
In a moment the doctor was prone on the floor. He tossed the knife out to the key. His aim was good and it fell directly beyond. With trembling hands he drew the knife toward him. It reached the key. Scarcely daring to breathe, he pulled it closer. The key had risen over the ridge which had held it, and was adhering to the knife. In another moment, he stood erect, freed from the shackles which had bound him.
He made for the door at a run, but a sudden thought stopped him. The clock showed him that an hour and twenty minutes had passed.
"Carnes must be nearly here!" he cried. "If I go blundering out, I'm liable to run right into the trap they have laid for him, and then we're both gone. If I yell to warn him, the fool will come ahead at full tilt. What the dickens can I do?"
His gaze fell on the can of radite. The wires leading to the interrupter fuse gleamed a dull gold with a malign significance.
"If Carnes and I are both washed out, there will be only Thelma left. She can't fight Saranoff alone. Carnes knows the man and his methods. There is only one way that I can see to warn him out of the trap."
He shuddered a moment. With a steady step he walked across the cave to the can of deadly explosive. A pair of pliers lay on a nearby bench. He picked them up. He dashed his hand across his face for a moment, but looked up with steady eyes. With hands that did not tremble, he bent down over the can. With a quick snip, he severed the wires leading to the can of radite.

Operative Carnes jumped ashore as the boat reached the bank of Bush River. Before him stretched a dismal swamp, interspersed with occasional bits of higher ground. He looked back over the river for a moment, taking his bearings with great care. A luminous lensatic compass gave him the orientation of the points he had chosen for markers.
"Are you sure we are at the right place?" he asked in an undertone.
"Sure as shootin', Mister," replied the boatman. "It's the only place of its kind in five miles. The rock you're hunting for is about a hundred rods due east."
"It looks right," said Carnes. "Come on, men."
Operatives Haggerty and Dillon scrambled out of the boat and stood by his side.
"Follow me," said Carnes in a whisper.
Both detectives nodded silently. They drew their pistols and fell in behind their leader. Keeping his direction with the aid of his compass, Carnes led the way forward, counting his steps. At five hundred he paused.
"It should be right here," he whispered.
Haggerty pointed in silence. In the starlight, a large rock loomed up a few yards away. With an exclamation of satisfaction, Carnes led the way to it.
"Dig on the south side," he whispered, "and hurry! The damned thing is due to go off in less than twenty minutes. Unless we can find and cut the wire before then, the doctor is a gone gosling."
The two detectives drew intrenching shovels from their pockets and dug feverishly. For five minutes they labored. Dillon gave an exclamation.
"Here it is, Chief!" he said.
Carnes bent down and ventured a short flash from a carefully guarded light. The detective's shovel had unearthed a powerful cable running through the earth.
"Get something to cut on!" cried Carnes.
Haggerty lifted a rock which they had unearthed and thrown to one side. Carnes raised the cable and laid it on the rock.
"Now for your ax, Dillon!" he exclaimed.
He turned on his flashlight. Dillon raised a hand-ax and took careful aim. Sparks flew as the ax fell on the rock, severing the cable cleanly. Carnes rose to his feet.
"The doctor's safe!" he cried.
* * * * *
He started at a run toward the north. He had gone only a few feet when a beam of light flashed across the marsh, picking him out of the darkness. He paused in amazement.
A flash of orange light stabbed the darkness and a heavy pistol bullet sang past his head. The detective raised his weapon to reply, but three more flashes from the darkness were followed by the vicious cracks of large caliber automatics.
"Down, Chief!" cried Haggerty.
Carnes dropped to the ground, the beam of light following his movements. Four more flashes came from the darkness. Mud was thrown up into his face. Dillon's gun joined Haggerty's in barking defiance into the night.
A groan came from Haggerty.
"Hit, Tom?" asked Carnes anxiously.
"A little, but don't let that bother you. Get that damned light!"
He fired again, groaning at he did so. There was a crash from over the marsh and the light went out.
"Good work, Tom!" cried Carnes.
He raised his pistol and fired again and again into the darkness, from which still came the flashes of orange light. A cry of pain rewarded him.
"Come on, men, rush them!" he cried.
He jumped to his feet and dashed forward. A fresh beam of light stabbed a path through the darkness. A volley of fire came from behind it. Haggerty stumbled and fell.
"They've got me, Chief!" he cried faintly.
Disregarding the storm of bullets, Carnes charged ahead, Dillon at his heels. A sudden shout came from his left. A fresh beam of light made a path through the darkness and Carnes could see his opponents lying prone on the marsh. A cry of dismay came from them. Carnes fired again as he rushed forward. The men leaped to their feet and fled away into the darkness.
"Your light, Dillon!" he cried.
Dillon's light shon
e out and picked up one of the fleeing figures. The beam from the left was centered on another.
"Halt!" came a stern voice from behind the light. "You are surrounded! If I give the word to fire, you are dead men!"
"Dr. Bird!" cried Carnes in amazement.
* * * * *
The fleeing man in the beam of Dillon's light paused.
"Drop your gun!" cried Carnes sharply.
There was a moment of hesitation before the man's gun fell and his hands went up.
"Get him, Carnes!" came Dr. Bird's voice. "I've got another one held out here. I hope one of them is the man we want."
As Dillon slipped handcuffs on his prisoner, Dr. Bird came forward, driving another Russian before him. In his hand was a piece of iron pipe.
"Cuff him, Carnes!" he said.
The detective slipped handcuffs on the man while Dr. Bird bent down and examined the face of each of the prisoners with his light. He straightened up with an exclamation of anger.
"These are nothing but tools," he said bitterly. "We had the arch-conspirator himself in our hands and let him escape."
"The arch-conspirator!" gasped Carnes. "You don't mean Saranoff?"
"Yes, Ivan Saranoff. He was here on this marsh to-night. There were four of his men and we got two, letting the most important one get away."
"You've got four, Dr. Bird," said a guttural voice from the dark.
Dr. Bird whirled around and shot out the beam of his light. A third Russian was revealed in its gleam.
"Hands up!" cried the doctor.
"I'm willing to be captured, Doctor," said the Russian. "Your search for Saranoff is useless. He has been gone for an hour. He is not one to risk his own skin when others will risk theirs for him. He fled after he left the cave."
"Do you know where he has gone?"
"I wish I did, Doctor. If I knew, we'd soon have him, I hope."
The Russian's voice had changed entirely. Gone were the heavy guttural tones. In their place was a rich, rather throaty contralto. Carnes gave a cry of astonishment and turned his light on the prisoner.
