It was night. The mausoleum was in the center of a silent cemetery. The black-clad man moved among the tombstones until he reached a high picket fence.

Like a weird specter coming from the abode of the dead, he swung himself over the barrier and walked along a dirt road. It led to a highway. Farther on glimmered the lights of a little store.

The Shadow was faltering now. His strength had been sapped by the ordeals which he had undergone.

He managed to reach the store.

A man behind the counter was startled by the sight of the tall, black-clad being who entered. The Shadow spoke to him, in a voice that resembled that of Clifford Gage.

"Call me a cab," he said.

Half an hour later, a cab was speeding to New York. In the back seat, a man lay almost invisible, beneath the spreading folds of his black cloak.

He jostled back and forth whenever the cab turned a curve. He was oblivious of his journey until the taxi driver rapped against the window.

"Here we are, sir," he said.

"Wait here," ordered the pa.s.senger.

The cab was standing in front of a house on Ninety-sixth Street. The man in the black cloak climbed the steps and entered. The Shadow went to a room on the second floor. There, in the darkness, he opened a drawer in a table and produced various objects which he distinguished purely by touch. He stowed them in the pockets of his coat.

Then he placed something upon his face and worked nimbly, still in darkness. He threw aside his cloak and hat. He took an automatic from the drawer and pocketed it.

When he again appeared upon the street, his face was that of Clifford Gage. The taximan stared at his pa.s.senger.

Entering the cab, Gage gave him the address of Doctor Heinrich Zerndorff's apartment.

In his apartment, the criminologist stared in amazement at his visitor.

"Where have you been?" he exclaimed. "Have you not found this man that you have sought?"

"The Black Master?" questioned Gage quietly. "Yes, I have found him. Last night -"

He stopped and suddenly picked up a newspaper that lay on the table. It bore the imprint of July 8th.

In huge headlines, it told of the electrocution of the three men who had placed the bombs. It announced that Sforza and Pecherkin would die the next day.

"One week," murmured Gage. Even to The Shadow this was amazing. He realized that he had lain helpless for more than seven days. He recalled the words of The Black Master - "You shall taste of death -"

He glanced at Zerndorff. The German was looking at him sympathetically. He seemed to understand what was pa.s.sing in the mind of Clifford Gage.

"These men," declared Gage, pointing to the newspaper, "are innocent! Innocent, do you understand?

Those who have died were guilty, although they were but tools of The Black Master! We must save these two -"

"Save them?" echoed Zerndorff.

"Yes!" replied Gage. "I met The Black Master! I have found his lair! Cardona was to capture him, but he failed me!"

"Ah!" Zerndorff's eyes lighted in understanding. "He has told me of it, yes. There was a house where he was to go, one night - but he did not go until the next night -"

"And he found?"

"Nothing! An empty house! He believed that it was a hoax. A hoax, yes."

"Where is Cardona now?"

"He has gone from town, I believe" - Zerndorff's eyes lighted suddenly - "but there is evidence at police headquarters. I have received letters, which I have given to the police - letters that have threatened me with bombs.

"They have believed that they have come from friends of these two men - Sforza and Pecherkin. Perhaps this man you call The Black Master - he has sent them?" Doctor Zerndorff picked up the telephone. He called police headquarters and talked to a detective.

"It is Doctor Zerndorff, yes," he said. "Those letters which have come to me - I wish a friend of mine to see them. He will be there soon, yes. His name is Mr. Gage. You understand, yes?"

He hung up the telephone.

"You have no clue?" Zerndorff questioned. "Nothing you have found? We must think of everything, yes!"

"Only this." From his pocket, Gage produced the token of The Black Master. "I had two of them. One was taken away. This was left."

"You must keep it with you!" declared Zerndorff. "It is important! Go, now, to police headquarters."

Gage left. He rode in a cab to headquarters. There he was shown two crudely penciled letters - threats against the life of Doctor Zerndorff. Gage smiled as he studied them.

"No use," he said, giving them back to the detective.

"Doctor Zerndorff phoned while you were on the way," replied the man. "He says that his limousine will be outside to bring you back. His man, Otto, has a message that he is to give to you."

Clifford Gage walked to the street door. He was smiling now, and as he stepped into the darkness, he laughed softly.

The laugh was scarcely more than an echo - yet it was a mysterious laugh - the laugh of The Shadow!

The limousine was awaiting its pa.s.senger. Otto stood beside it on the curb.

Clifford Gage reached in his pocket. He withdrew the black disk which he found there. He smiled grimly as he studied the small token of The Black Master.

"Threats," he murmured. "Threats against the life of Doctor Zerndorff. Threats - from whom?"

He dropped the black disk into a crevice beside the steps and his face gleamed with satisfaction as he watched it fall from view.

Then, with a strange, knowing smile on his face, Clifford Gage descended to the limousine. Otto saluted him in military fashion. Gage entered the car.

As the limousine rolled forward, he moved from the back seat and raised the cushion. He turned the ray of a flashlight into the s.p.a.ce. There, in a coverless box, was the reflected surface of a polished bra.s.s bomb - the duplicate of the instrument of death that the police had found in the Financial Building.

"The agents of The Black Master," came a low, whispered voice. It was the voice of The Shadow, issuing from the lips of Clifford Gage. "Their deaths have been timed. They have perished by his design.

Deaths by explosions!

"Those stopped, and to one man came an unexpected fate. Killer Bryan was killed while fighting the police. Like the others, he died at the hand of The Black Master. Now the explosions are to begin again - timed for the arrival of the victim."

His voice ended in a hollow, whispered laugh. There was silence; then came the voice of Clifford Gage, speaking to Otto in the front seat. The man at the wheel responded with a "Ja!" as he received instructions from his pa.s.senger. The limousine turned into a side street. The man in the back seat was silent - thinking - planning!

CHAPTER XXII. THE SHADOW'S TURN.

Resting in his easy-chair, Doctor Heinrich Zerndorff sat waiting. He was lost in deep thought, his hands in the pockets of his dressing gown, his head bowed in contemplation.

It was less than an hour since Otto had left for police headquarters to bring back Clifford Gage. The trip was not a long one. Doctor Zerndorff was expecting news.

The door opened behind the seated man - so silently that Doctor Zerndorff did not hear it. There was a faint rustling. This did not reach his ears.

The first inkling that someone had entered the room came to Doctor Zerndorff when he glanced upward because of a sudden impulse. He found himself staring into the muzzle of an automatic. It was held by a mysterious stranger, a man who wore a black cloak and whose face was obscured by the turned-down brim of a broad felt hat.

"The Shadow!" Doctor Zerndorff raised his hands instinctively as he exclaimed the name.

"The Shadow!" came a whispered echo from the man in the black cloak. "The Shadow, come to claim a reckoning!"

A thin smile played over Doctor Zerndorff's features. He stared at the man before him, as though he could penetrate the disguise that covered that unknown countenance.

"A reckoning?" questioned Zerndorff.

"Yes!" declared The Shadow. "I have found The Black Master! Your deception was a great one, Zerndorff. Tonight I stood within ten feet of death and failure. But, all along, I understood. Now it is you who will meet destruction!"

The German seemed unperturbed.

"Those bombs that you pretended to be a mystery," continued The Shadow. "The key to them lay in the black disks - the tokens of the Master.

"The sensitive mechanism of the bombs responded only to the presence of a metal which contained a mild radium activity. Its glow was concealed by its black surface.

"Each token - and all your followers carried one - set off a bomb when the victim came close to it."

"I should have known it when Perry Warfield entered the office in the Financial Building. But I did not understand it until now.

"The clue to your ident.i.ty was Killer Bryan. He alone, of all your men, died by a hand that did not seem to be The Master's. There was method in it.

"You wanted Killer Bryan to die with his lips sealed. You notified him - as The Master - to be ready.

You planned that he should kill Cardona, the only detective in New York who might have fathomed your schemes. You were there to slay Bryan in defense of Cardona - a justifiable homicide.

"But for my presence, Cardona would have died before you fired. Had Bryan not confessed, Henry Arnaud would have been hunted as a murderer - another dangerous foe to be destroyed." Doctor Zerndorff let his hand rest upon the arm of his chair. The Shadow permitted the action. He knew that Zerndorff had not been prepared for this visitation; that the man who played the part of The Black Master believed his enemy to be dead.

"I suspected you when I visited you as Clifford Gage," The Shadow continued. "Once you forgot yourself - you slipped momentarily from your dialect.

"Why do you think I pretended to be working with you? Because I knew that if I treated you as a confidant, you would believe me ignorant.

"I told you that I would go into any trap that The Black Master might lay. So you furnished me with clues and prepared the trap.

"You thought I was duped; even when you knew that I had called in Cardona's aid, you did not realize that I had learned your game.

"I understand those threatening letters that you sent to yourself. They were clear to me before I reached headquarters. Otto knew too much about you - or, may I say, you feared that he might know too much?

"By planting a black token upon him, you intended to destroy him in your own car - proof that threats were directed against you. Then I came along - with the disk in my possession - and you seized the opportunity.

"I had not antic.i.p.ated Cardona's failure to be at hand. I know now that you talked with him and learned enough to prepare for my coming, and direct him elsewhere.

"You had your opportunity to destroy me. You did not use it. I escaped from your impenetrable prison.

"I am here now, with one purpose - to save those innocent men. Because of the death that threatens them, I offer you life. But it must be life free from crime. One false step on your part, and our truce will be ended!"

Doctor Zerndorff bowed submissively.

The Shadow drew a paper from his pocket. He extended it to Doctor Zerndorff. It contained a brief confession of the criminologist's crime and an admission of his ident.i.ty.

"Sign," said The Shadow.

Doctor Zerndorff obeyed.

"This," declared The Shadow, "will bring the governor's stay of execution. He is here in New York City tonight. He will be reached.

"As for you, Doctor Zerndorff, I can abide by my promise. I am prepared for any emergency - as I was prepared when I was in the vault where you placed me.

"Your escape is guaranteed. Tonight a fast plane will take you -"

Doctor Zerndorff raised a hand in interruption. The Shadow paused, intuitively knowing that the man had something important to say.

"I have obeyed your commands" - it was the monotonous voice of The Black Master, coming from Zerndorff's lips - "and you have promised me life. But I shall not live! I shall die! "My career of crime will not end! It will continue after I have gone!

"Listen carefully to what I have to say. You will be interested - and powerless.

"I have three types of bombs. Vervick was the man who supplied the additional knowledge that I needed. His weakness was money.

"I acted quickly when the Evening Cla.s.sic offered its reward. I phoned Vervick, telling him I was a reporter who wished to see him. I tipped off the reporter, without his knowing who had called. The understanding was silence, until Vervick reached Raynor's office.

"Meanwhile, Michaels placed the bomb. He was one of three ignorant men who served me. All are dead, as they deserve to be.

"One thing Vervick did not know. He carried the token of The Black Master. He did not know that it contained the metallic element that discharged the bombs.

"That was my invention; Vervick simply followed my instructions. He also made the time bombs and the radio bombs - the other two types. Those are the ones that I am using now!"

The emphasis on the last words had an effect upon The Shadow. He knew that Zerndorff's schemes were not yet ended. He waited patiently, hoping for further information. He was not to be disappointed.

"I have told you this to please myself," declared Zerndorff. "You are the only man who can appreciate my cleverness.

"At this moment, three giant bombs are placed. One is under the base of the Manhattan Bridge. The second is buried in the depths of the vehicular tunnel that leads to New Jersey. The third is in the largest hospital in New York City.
