and came down. Did he come? Has he been here? Have you caught him? Oh! why don't you answer me, instead of staring at me like this? Can't you see how nervous, how frightened, I am? Dear Heaven! will no one tell me what has happened?"

"Nothing has happened, miss," answered Petrie, catching her eye as she flashed round on him. "You'd better go back to bed. Nobody's been here but Sir Horace. The noise you heard was me a-grabbing of him, and he and Mr. Narkom a-tumbling over something as they went down to look at the furnace."

"Furnace? What furnace? What are you talking about?" she cried agitatedly. "What do you mean by saying that Sir Horace came down?"

"Only what the superintendent himself will tell you, miss, if you ask him. Sir Horace came downstairs in his pyjamas a few minutes ago to say as he'd recollected about the flues of the furnace in the cellar being big enough to hold a man, and then him and Mr. Narkom went below to have a look at it."

She gave a sharp and sudden cry, and her face went as pale as a dead face.

"Sir Horace came down?" she repeated, moving back a step and leaning heavily against the bannister. "Sir Horace came down to look at the furnace? We have no furnace!"

"What!"

"We have no furnace, I tell you, and Sir Horace did not come down. He is up there still. I know—I know, I tell you—because I feared for his safety, and when he went to his room I locked him in!"

"Superintendent!" The word was voiced by every man present, and six pairs of eyes turned toward Narkom with a look of despairing comprehension.

"Get to the cellar. Head the man off! It's he—the Cracksman!" he shouted out. "Find him! Get him! Nab him, if you have to turn the house upside down!"

They needed no second bidding, for each man grasped the situation instantly, and in a twinkling there was a veritable pandemonium. Shouting and scrambling like a band of madmen, they lurched to the door, whirled it open, and went flying down the staircase to the kitchen and so to a discovery which none might have foreseen. For, almost as they entered they saw lying on the floor a suit of striped pyjamas, and close to it, gagged, bound, helpless, trussed up like a goose that was ready for the oven, gyves on his wrists, gyves on his ankles, their chief, their superintendent, Mr. Maverick Narkom, in a state of collapse, and with all his outer clothing gone!

"After him! After that devil, and a thousand pounds to the man that gets him!" he managed to gasp as they rushed to him and ripped loose the gag. "He was here when we came! He has been in the house for hours. Get him! get him! get him!"

They surged from the room and up the stairs like a pack of stampeded animals; they raced through the hall and bore down on the picture-gallery in a body, and, whirling open the now closed door, went tumbling headlong in.

The light was still burning. At the far end of the room a window was wide open, and the curtains of it fluttered in the wind. A collection of empty cases and caskets lay on the middle table, but man and jewels were alike gone! Once again the Vanishing Cracksman had lived up to his promise, up to his reputation, up to the very letter of his name, and for all Mr. Maverick Narkom's care and shrewdness, "Forty Faces" had "turned the trick" and Scotland Yard was "done!"

III

Through all the night its best men sought him, its dragnets fished for him, its tentacles groped into every hole and corner of London in quest of him, but sought and fished and groped in vain. They might as well have hoped to find last summer's partridges or last winter's snow as any trace of him. He had vanished as mysteriously as he had appeared, and no royal jewels graced the display of Miss Wyvern's wedding gifts on the morrow.

But it was fruitful of other "gifts," fruitful of an even greater surprise, that "morrow." For the first time since the day he had given his promise, no "souvenir" from "The Man Who Called Himself Hamilton Cleek," no part of last night's loot came to Scotland Yard; and it was while the evening papers were making screaming "copy" and glaring headlines out of this that the surprise in question came to pass.

Miss Wyvern's wedding was over, the day and the bride had gone, and it was half-past ten at night, when Sir Horace, answering a hurry call from headquarters, drove post haste to Superintendent Narkom's private room, and passing in under a red and green lamp which burned over the doorway, entered and met that "surprise."

Maverick Narkom was there alone, standing beside his desk, with the curtains of his window drawn and pinned together, and at his elbow an unlighted lamp of violet-coloured glass, standing and looking thoughtfully down at something which lay before him. He turned as his visitor entered and made an open-handed gesture toward it.

"Look here," he said laconically, "what do you think of this?"

Sir Horace moved forward and looked; then stopped and gave a sort of wondering cry. The electric bulbs overhead struck a glare of light down on the surface of the desk, and there, spread out on the shining oak, lay a part of the royal jewels that had been stolen from Wyvern House last night.

"Narkom! You got him, then—got him after all?"

"No, I did not get him. I doubt if any man could, if he chose not to be found," said Narkom bitterly. "I did not recover these jewels by any act of my own. He sent them to me; gave them up voluntarily."

"Gave them up? After he had risked so much to get them? God bless my soul, what a man! Why, there must be quite half here of what he took."

"There is half—an even half. He sent them to-night, and with them this letter. Look at it, and you will understand why I sent for you and asked you to come alone."

"There's some good in even the devil, I suppose, if one but knows how to reach it and stir it up," Sir Horace read. "I have lived a life of crime from my very boyhood because I couldn't help it, because it appealed to me, because I glory in risks and revel in dangers. I never knew where it would lead me—I never thought, never cared—but I looked into the gateway of heaven last night, and I can't go down the path to hell any longer. Here is an even half of Miss Wyvern's jewels. If you and her father would have me hand over the other half to you, and would have 'The Vanishing Cracksman' disappear forever, and a useless life converted into a useful one, you have only to say so to make it an accomplished thing. All I ask in return is your word of honour (to be given to me by signal) that you will send for Sir Horace Wyvern to be at your office at eleven o'clock to-night, and that you and he will grant me a private interview unknown to any other living being. A red and green lantern hung over the doorway leading to your office will be the signal that you agree, and a violet light in your window will be the pledge of Sir Horace Wyvern. When these two signals, these two pledges, are given, I shall come in and hand over the remainder of the jewels, and you will have looked for the first time in your life upon the real face of 'The Man Who Calls Himself Hamilton Cleek.'"

"God bless my soul! What an amazing creature—what an astounding request!" exclaimed Sir Horace, as he laid the letter down. "Willing to give up £20,000 worth of jewels for the mere sake of a private interview! What on earth can be his object? And why should he include me?"

"I don't know," said Narkom in reply. "It's worth something, at all events, to be rid of 'The Vanishing Cracksman' for good and all; and he says that it rests with us to do that. It's close to
