He pulled back the curtains and glared out of the window. There was no need to ask any further questions. The house was surrounded. He swung round again at his tormentor and faced the white mask in a blind fury of rage.

"You're clever, aren't you?" he said. "Cleverer than all the police! But you weren't clever enough to save your son from death!"

The masked figure reeled back.

"Ah, that's got you! Little Jack o' Judgment!" mocked the colonel.

"That's got you where it hurts you most, hasn't it? Your only son, too!

And he went to the devil all the faster because of me--me--me!" He struck his breast with his clenched fist. "You can't bring him back to life, can you? That's one I've got against you."

"No," said Jack o' Judgment in a low voice. "I cannot bring him back to life, but I can destroy the man who destroyed him, who blighted his young life, who taught him vicious practices, who sapped his vitality with drugs----"

"That's a lie!" said the colonel. "Crewe picked him up at Monte Carlo, when he was on his beam-ends."

"Who sent him to Monte Carlo?" asked the other. "Who was the gambler who brought him down, and received the wreck he had made with the pretence that he had never met him before? It was you, Boundary?"

The colonel nodded.

"I was a fool to deny it. I pretended to Crewe that I hadn't met him before. Yes, it was I, and I glory in it. You think you're going to pinch me, now, and put me where I belong--on the scaffold maybe. But you can never wipe that memory out of your mind, that you had a son who died in the gutter, that you're a childless old man who has no son to follow you!"

"I can't wipe that out!" said Jack o' Judgment. "O, G.o.d! I can't wipe that out!"

He raised his hand to his masked face as though to hide the picture which Boundary conjured up.

"But I can wipe you out," he said fiercely, "and I've given my life, my career, my reputation, all that I hold dear to get you! I've smashed your schemes, I've ruined you, even if I've ruined myself. They're waiting for you downstairs, Boundary. I told them to be here at this very minute. Stafford King----"

"You'll never see me taken," said Boundary.

Two shots rang out together, and the colonel sprawled back over the bed--dead.

Propped against the wall was Jack o' Judgment, and the hand that gripped his breast dripped red. They heard the shots outside and Stafford King was the first to enter the room. One glance at the colonel was sufficient, and then he turned to the figure who had slipped to the floor and was sitting with his back propped against the wall.

"Good G.o.d!" said Stafford. "Jack o' Judgment!"

"Poor old Jack!" said the mocking voice.

Stafford's arm was about his shoulder, and he laid the head gently back upon his bent knee. He lifted the mask gently and the light of the oil lamp which swung from the ceiling fell upon the white face.

"Sir Stanley Belcom! Sir Stanley!" he softly whispered.

Sir Stanley turned his head and opened his eyes. The old look of good-humour shone.

"Poor old Jack o' Judgment!" he mimicked. "This is going to be a first-cla.s.s scandal, Stafford. For the sake of the service you ought to hush it up."

"But n.o.body need know, sir," said Stafford. "You can explain to the Home Secretary----"

Sir Stanley shook his head.

"I'm going to see a greater Home Secretary than ever lived in Whitehall," he said slowly. "I'm finished, Stafford. Strip this mummery from me, if you can."

With shaking hands Stafford King tore off the black cloak and flung it under the bed.

"Now," said Sir Stanley weakly, "you can introduce me to the provincial police as the head of our department and you can keep my secret, Stafford--if you will."

Stafford laid his hand upon Sir Stanley's.

"I told my solicitor," Sir Stanley spoke with difficulty, "to give you a letter in case--in case anything happened. I know I haven't played the game by the department. I ought to have resigned years ago when I found what had happened to my poor boy. I was Chief of Police in one of the provinces of India at the time, but they wouldn't let me go. I came to Scotland Yard and was promoted--no, I haven't played the game with the department. And yet perhaps I have."

He did not speak for some time.

His breathing was growing fainter and fainter, and when Stafford asked him, he said he was in no pain.

"I had to deceive you," he said after awhile. "I had to pretend that Jack o' Judgment called on me too. That was to take suspicion from your--Miss White," he smiled. "No, I haven't played the game. I stood for the law, and yet--I broke that gang, which the law could not touch.

Yes, I broke them! I broke them!" he whispered. "If Boundary hadn't known me I should have been gone before you came and resigned to-morrow," he said, "but he must have discovered the boy's name. I wonder he hadn't tried before. I smashed them, didn't I, Stafford? It cost me thousands. I have committed almost every kind of crime--I burgled the diamondsmiths', but you must give me your word you will never tell. Phillopolis must suffer. They must all be punished."

Stafford had sent the police from the room, but the police-surgeon would not be denied. He had the sense to see that nothing could be done for the dying man, however, and that a change of position would probably hasten the end. He, too, went and left them alone.

"Stafford, I have quite a lot of money," said the First Commissioner; "it is yours. There's a will ... yours...."

Then he ceased to speak and Stafford thought that the end had come but did not dare move in case he were mistaken. After five minutes the man in his arms stirred slightly and his voice sounded strangely clear and strong.

"Gregory, my boy, good old Gregory! Father's here, old man!"

His voice died away to a rumble and then to a murmur.

The tears were running down Stafford's face. He sensed all the tragedy, all the loneliness of this man who had offered so cheerful a face to the world. Then Sir Stanley struggled to draw himself to his feet, and Stafford held him.

"Gently, sir, gently," he said, "you're only hurting yourself."

The dying man laughed. It was a little shrill chuckle of merriment and Stafford's blood ran cold.

"Here I am, poor old Jack o' Judgment! Little old Jack o' Judgment! Give me the lives you took and the hopes you've blasted. Give them to Jack ... Jack o' Judgment!"

They were his last words.

A year later First Commissioner Sir Stafford King received a letter from South America. It contained nothing but the photograph of a very good-looking man, and a singularly pretty woman, who held in her lap a very tiny baby.

"Here is the last of the Boundary Gang," said Sir Stafford to Maisie.

"It is the one happy ending that has emerged from so much misery and evil."

"Why, it is Lollie Marsh!"

"Lollie Crewe, I think her name is now," said Stafford. "It was queer how Sir Stanley recognised the only human members of the gang."

"Then they got away after all?" said the girl. "I've often wondered what happened at that aerodrome."

Stafford laughed.
