Pinto leapt the parapet and was following swiftly in its wake. He guessed rather than knew that for once Jack o' Judgment had come unarmed, and a wild exultation filled him at the thought that it was left to him to unveil the mystery which was weighing even upon the iron nerve of the colonel.

The figure gained the shrubbery, and the pursuer heard the rustle of leaves as it plunged into the depths. In a second he was blundering after. He lost sight of his quarry and stopped to listen. There was no sound.

"Hiding," grunted Pinto. And then aloud: "Come out of it. I see you and I'll shoot you like a dog if you don't come to me!"

There was no reply. He dashed in the direction he thought Jack o' Judgment must have taken and again missed. With a curse he turned off in another direction and then suddenly glimpsed a shape before him and leapt at it. He was flung back with little or no effort, and stood bewildered, for the coat his hand had touched was rough and he had felt metal buttons.

"A soldier!" he gasped. "Who are you?"

"Steady," said the other; "don't get rattled, Pinto."

"Who are you?" asked Pinto again.

"My name is Stafford King," said the soldier, "and I think I shall want you."

Pinto half turned to go, but was gripped.

"You can go back to Huddersfield and pack your boxes," said Stafford King. "You won't leave the town except by my permission."

"What do you mean?" demanded Pinto, breathing heavily.

"I mean," said Stafford King, "that the unfortunate man you tried to blackmail must prosecute whatever be the consequence to himself. Now, Pinto, you've a grand chance of turning King's evidence."

Pinto made no reply. He was collecting his thoughts. Then, after a while, he said:

"I'll talk about that later, King. I'm staying at the Huddersfield Arms. I'll meet you there in an hour."

Stafford King did not move until the sound of Pinto's footsteps had died away. Then he began a systematic search, for he too was anxious to end the mystery of Jack o' Judgment. He had followed Pinto when he dashed from the room and had heard the Portuguese calling upon Jack o' Judgment to surrender. That mysterious individual, who was obviously lying low, could not be very far away.

He was in a shrubbery which proved later to be a clump of rhododendrons, in the centre of which was a summer-house. To the heart of this shrubbery led three paths, one of which Stafford discovered quite close at hand. The sound of gravel under his feet gave him an idea, and he began walking backward till he came to the shadow of a tree, and then, simulating the sound of retreating footsteps, he waited.

After a while he heard a rustle, but did not move.

Somebody was coming cautiously through the bushes, and that somebody appeared as a shadowy, indistinct figure, not twenty yards away. Only the keenest eyesight could have detected it, and still Stafford waited. Presently he heard the soft crunch of gravel under its feet, and at that moment leapt towards it. The figure stood as though paralysed for a second, and then, turning quickly, fled back to the heart of the bushes. Before it had gone a dozen paces Stafford had reached it, and his arm was about its neck.

"My friend," he breathed, "I don't know what I'm to do with you now I've got you, but I certainly am going to register your face for future reference."

"No, no," said a muffled voice from behind the mask. "No, no, don't; I beg of you!"

But the mask was plucked away, and, fumbling in his pocket, Stafford produced his electric lamp and flashed it on the face of his prisoner. Then, with a cry of amazement, he stepped back--for he had looked upon the face of Maisie White!

For a moment there was silence, neither speaking. Then Stafford found his voice.

"Maisie!" he said in bewilderment, "Maisie! You--Jack o' Judgment?"

She did not answer.

"Phew!" whistled Stafford.

Then sitting on a trunk, he laughed.

"It is Maisie, of all people in the world. And I suspected it, too!"

The girl had covered her face with her hands and was crying softly, and he moved towards her and put his arm about her shoulder.

"Darling, it is nothing very terrible. Please don't go on like that."

"Oh, you don't understand, you don't understand!" she wailed. "I wanted to catch Silva. I guessed that he was coming north on one of his blackmailing trips, and I followed him."

"Did you come up by the same train?"

He felt her nod.

"So did I," said Stafford with a little grin.

"I followed him to the bazaar," she said, "and then I watched him from a little eating-house on the opposite side of the road. Do you know, I wondered whether you were here too, and I looked everywhere for you, but apparently there was nobody in sight when Pinto came out with Lady Sybil, only a soldier."

"I was that soldier," said Stafford.

"I discovered where Mr. Crotin lived and came up later," she went on. "Of course, I had no very clear idea of what I was going to do, and it was only by the greatest luck that I found the window of the library open. It was the only window that was open," she said with a little laugh.

"It wasn't so much your luck as my forethought," smiled Stafford.

"Now I want to tell you about Jack o' Judgment," she began, but he stopped her.

"Let that explanation wait," he said; "the point is, that with your evidence and mine we have Pinto by the throat--what was that?"

There was the sound of a shot.

"Probably a poacher," said Stafford after a moment. "I can't imagine Pinto using a gun. Besides, I don't think he carries one. What did he throw at you?"

"A knife," she said, and he felt her shiver; "it just missed me. But tell me, how have we got Pinto?"

They had left the shrubbery and were walking to............
