As he hacked the fragments of tissue from the torso the fiend carefully deposited each in the huge cask. At such times a faint boiling sound was heard, and there arose an effluvium that bade fair to overcome even the monster engaged in the foul work. At last the limbs and head had been entirely removed. The Professor evidently decided that the trunk should be left whole, and he put his entire strength into the job of getting it into the cask. It was almost more than he could negotiate, but finally a dull splash told that he had succeeded.

At this moment Jimmie O'Hara came out of his trance. The horrible proceeding had left him faint and shaken, and he wished heartily that he could leave the disgusting place as fast as his legs could carry him.

But there was still work to be done and he resolved to get it over.

The lantern! First he must put that out of commission. The maniac would then be at his mercy. Slowly, steadily he stole through the doorway, his eyes glued to the Professor's back. Now he was within a yard of the lantern, and he drew back his foot for the kick.

Next moment Jimmie found himself gazing into the glaring eyes of his intended victim. Instinctively he struck out with the clubbed automatic, but the blow must have fallen short, or else the Professor had developed an uncanny agility. Now to his horror he saw the flashing blade of the bloodstained ax raised on high. He had no time to dodge the blow. He pressed the trigger of the Colt from the position in which he held it.

The bullet grazed the upraised arm. The ax fell toward O'Hara from fingers lacking strength to retain it, and he grasped it by the handle in midair. The next moment the a.s.sa.s.sin collected his wits and sprang at him. Silently, the breath of both coming in gasps, the two men strove, each clawing desperately at the other's throat. The reporter fought with the knowledge that should he lose he would never again see the light of day, the other with the fear of the justice that would deal with him.

The maniac hugged his arms tightly about Jimmie, pinioning him so tightly that the reporter could not use his gun. At length their convulsive movements brought the men close to the lantern, and the next instant the cellar was plunged in darkness. A second later the Professor tripped over some hidden obstruction and fell, dragging his opponent with him to the earthen floor. To Jimmie's surprise there was no further movement from the body beneath him. Could the old villain be playing possum? He cautiously shifted his hold and grasped the hidden throat. He pressed the Professor's windpipe for a moment, but there was no answering struggle. Slowly the truth dawned upon him. The heavy fall to the floor had rendered the older man insensible.

He must work fast. Reaching into his pocket he brought out the ever handy electric torch and flashed it over the features of his prisoner.

Kell was breathing heavily. With dexterous hands O'Hara swiftly went through the old man's pockets, removing all which might tend to make that worthy dangerous--an ugly looking pistol of large caliber, a blackjack similar to his own and a small bottle.

The latter item Jimmie examined curiously, finally uncorking it and inhaling the contents. He inhaled, not wisely but too well. The fumes from the vial were nigh overpowering, and he reeled back nauseated. The cork he hastily replaced. Just what the nature of the powerful stuff was he never attempted to discover. One acquaintance was enough.

He staggered to his feet and got the lantern lighted, then sat, gun in hand, waiting for his prisoner's return to his senses. This was becoming increasingly imminent, judging by certain changes in the Professor's respiration. Finally there came a series of shuddering movements as the man attempted to raise his battered body.

"Get up, you d.a.m.ned butcher," ordered Jimmie, "and march upstairs. And just remember that I've got you covered; don't make any false moves." He prodded the prostrate form of the by now glaring fiend before him. The stench of the place was nearly overcoming him, and again he felt an overwhelming desire to dash madly from that den of evil, and once more breathe G.o.d's fresh air. Under the stimulus of several shoves the Professor finally won to his feet and stumbled up the stairs. Jimmie was taking no chances and kept the automatic sharply digging into the ribs of his prisoner. The fight, however, seemed temporarily to have been all taken out of the old man, and he made no resistance as the reporter drove him on up to the laboratory.

The room he found exactly as he left it. At a word from him Norma Manion came from her hiding place in the horrible room where she had been kept prisoner.

With an hysterical scream she fell limply to the floor. The sight of her father's murderer had proved too much for her. Forgetting his prisoner for the moment Jimmie sprang to the girl's side.

Kell chose this moment to make a dash for freedom. His footsteps, however, were not as noiseless as he had intended, and O'Hara whirled just in time to see his quarry about to throw open the hall door. Jimmie dove for his gun, only to encounter the Professor's mysterious vial, which, though forgotten, still lay in his pocket. With no time to think, he acted purely upon instinct. His arm drew back and the bottle flew straight for the Professor's head.

By a miracle the missile missed its mark. Came a shivering crash, as the bottle struck a stud in the ma.s.sive door. Of a sudden recalling the terrific potency of the contents of that particular bottle, Jimmie gasped in dismay. Norma Manion's safety drove every other thought from his mind. At any cost he must remove her from the proximity of those lethal fumes.

Hastily and without a backward glance, he gathered the girl into his arms and dashed into the room where he had first found her. Ascertaining that she had but swooned he placed her gently on the bed. In some perplexity as to his next move he stared at the beautiful face now so wan and white. Queer that he hadn't noticed the fact before--she was beautiful. He even took a second look, then noting a continued absence of all sound from the laboratory decided to investigate.

Gingerly he pushed open the door, sniffing the air cautiously as he advanced. To his nostrils gradually came a slight scent, which though almost imperceptible made his senses reel. As he approached the hall door he found the atmosphere heavy with the soporific vapors from the broken vial, and he staggered drunkenly.

He gave a start of surprise. On the floor, lying in a grotesque huddle which suggested a most unpleasant possibility, was the inert body of Professor Kell.

Jimmie bent over the body and put an experienced ear to the heart. Yes, there as a faint beat--very faint. Even as he listened he perceived a slight increase in the respiration. Now the breath began coming in great, choking gasps, only to die suddenly to next to nothing. At last with a rueful sigh Jimmie reached to his hip and produced the private O'Hara flagon. He stooped over the Professor's form once more and by dint of much prying at clenched jaws managed to force a sizeable charge of fiery liquid down the old man's throat. Jimmie had just begun to entertain a strong hope that this latter effort would bring the Professor to life, when his keen ear detected signs of a commotion below.

He sprang from his position over the slowly reviving Kell and leaped to a vantage point beside the door. A blackjack miraculously appeared from some hidden part of his anatomy and the ever-dependable Colt also became in evidence. Now came the banging of a door, m.u.f.fled voices, a crash as of a chair overturned in the dark. Up rolled a horrible oath, and the same was rendered in a voice to Jimmie sweetly familiar. Came the sound of footsteps on the stairway and several persons coming along the hall.

"Where in h.e.l.l is Jimmie?" roared a wicked voice. "If he's met with any monkey business in this h.e.l.l-hole I'll see that the d.a.m.ned place burns to the ground before I leave it!"

Delightedly Jimmie jerked open the door.

"Still alive, Chief," he chirped as the Old Man strode into the laboratory. Bland was followed by Perry, who seemed to be in a sort of daze. Bringing up the rear were a pair of plainclothesmen whom Jimmie knew very well--almost too well. One of these gentlemen bore a lantern which reminded Jimmie strongly of some he had seen that night guarding an open ditch in the public highway.

The Professor had fully regained consciousness and was struggling to his feet. As for Norma Manion, she had suddenly appeared, leaning weakly against the door casing, and was surveying the group in great alarm.

After being a.s.sured by O'Hara that they were her friends she smiled wanly. To Bland and the others she was, of course, an unexpected factor in the weird night's doings, and for several moments they regarded her curiously.

At length Jimmie, sensing the question in the Old Man's eyes, elected to offer a few words of explanation.

"Miss Manion has just been through a terrible experience," he said.

"She and her father have been for some time at the mercy of this monster"--indicating Kell--"and her nerves are completely shattered.

We'd better get her out of this as quickly as we can."

"Mike!" Hard Boiled Bland glared at one of the officers. "Don't stand there with your teeth in your gums like that. Take this girl out to my car and let her lie down. She needs a stimulant, too. If you search my car and find any red liquor in the left back door pocket, I don't know a thing about it. And stay with her so she won't be afraid to go to sleep."

She smiled in silent grat.i.tude and allowed the plainclothesman to lead her away from that chamber of horror.

The reporter lost no time in telling Bland of his failure to find Skip Handlon. He went on to acquaint his Chief with the facts of all that had occured while he had been at the Professor's house.

The fiery old fellow listened grimly. When Jimmie came to the story of the corpse and the cask the editor breathed one word, "Manion!"

Jimmie nodded sadly. All eyes turned to the dejected huddle on the floor that was Professor Kell. Finally Bland could wait no longer, but fixed a terrible eye on the murderer and demanded harshly, "Where's Handlon?"

Now the Professor burst into a fit of insane laughter, laughter that curdled the blood of the listeners.

"You ask me that! It's almost too good. Hee-hee! You sent your two precious reporters out to my house to pry into my secrets, and thought to display my name all over your yellow sheet; but you forgot that you were dealing with Professor Anton Kell, didn't you?" The last he fairly shrieked. "A lot of people have tried to intrude upon me before, but none ever escaped me!"

"We know that," cut in Jimmie, for he was getting impatient and the old man's boastings seemed out of place. "You are slated for the rope anyway, after what I discovered down cellar." He jerked his eyes in the direction of the door significantly. "Now we propose to find Handlon, and the better it will be for you if you tell us what you have done with him. Otherwise...."

"You can go to h.e.l.l!" screamed the maniac. "If you are so clever, find out for yourselves. He isn't so far away that you couldn't touch him by reaching out your hand. In fact, he's been with you quite a while.

Hee-hee-hee! Well, if you must know--there he is!" With an insane chuckle he pointed at Horace Perry. And Perry did a strange thing.

"Yes, you fiend, here I am!" Whose voice was that? Was it Perry speaking, or was it Skip Handlon? Most a.s.suredly Perry stood before them, but the voice, in a subtle manner, reminded the group strongly of poor old Skip.

As he spoke Perry had launched himself at the Professor's throat and had to be restrained by the others. Savagely he fought them but slowly and surely they overcame his struggles and placed him, writhing, in a chair.

Of a sudden Bland leaned forward and scrutinized Perry's face sharply.

Had the reporter gone insane too? The pupils of the eyes had taken on a sort of queer contraction, a fixed quality that was almost ludicrous. He looked like a man under hypnosis. He had gone limp in their grasp, but now suddenly he stiffened. The eyes underwent another startling change, this time glowing undoubtedly with the look of reason. Bland was mystified and waited for Perry to explain his queer conduct. The latter seemed finally to come to. Simultaneously he realized that his peculiar lapse from consciousness had been observed by the others.

"Guess I may as well admit it," he said with a wry smile. "Ever since I came back from my a.s.signment with Kell I have had a h.e.l.l of a time. Half the time I have been in a daze and have not had the least idea what I was doing. Funny part of it is that I have seemed to keep right on doing things even while I was out of my head." He told briefly of the visions he had had in which he had seemed to contend with his brother reporter, the horrid sensations as he felt himself overcome, the black oblivion in which he then found himself, and the mysterious manner in which he had left Keegan on that ill-fated a.s.signment.

"What have you done to Handlon?" Jimmie's voice cut in. He was standing over the form of the maniac, rigid and menacing. "You have exactly two minutes to go."
