sure that there's no wolf in sheep's clothing amongst them. With a fellow like that, a diabolical rascal with a diabolical gift

for impersonation, one can't be too careful. Meantime, it is just as well not to have confided this news to your daughters, who, naturally, would be nervous and upset; but I assume that you have taken some one of the servants into your confidence, in order that nobody may pass them and enter the house under any pretext whatsoever?"

"No, I have not. Miss Lorne advised against it, and, as I am always guided by her, I said nothing of the matter to anybody."

"Was that wrong, do you think, Mr. Narkom?" queried Ailsa anxiously. "I feared that if they knew they might lose

their heads, and that my cousins, who are intensely nervous and highly emotional, might hear of it, and add to our difficulties by becoming hysterical and demanding our attention at a time when we ought to be giving every moment to watching for the possible arrival of that man. And as he has always lived up to the strict letter of his dreadful promises heretofore, I knew that he was not to be expected before nightfall. Besides, the jewels are locked up in the safe in Sir Horace's consulting-room, and his assistant, Mr. Merfroy, has promised not to leave the room for one instant before we return."

"Oh, well, that's all right, then. I dare say there is very little likelihood of our man getting in whilst you and Sir Horace are here, and taking such a risk as stopping in the house until nightfall to begin his operations. Still, it was hardly wise, and I should advise hurrying back as fast as possible and taking at least one servant—the one you feel least likely to lose his head—into your confidence, Sir Horace, and putting him on the watch for my men. Otherwise, keep the matter as quiet as you have done, and look for me about nine o'clock. And rely upon this as a certainty: The Vanishing Cracksman will never get away with even one of those jewels if he enters that house to-night, and never get out of it unshackled!"

PULLING THEIR HAIR—RUBBING THEIR FACES WITH A CLEAN HANDKERCHIEF IN QUEST OF ANY TRACE OF "MAKE-UP" OR DISGUISE OF ANY SORT

With that, he suavely bowed his visitors out and rang up the pick of his men without an instant's delay.

Promptly at nine o'clock he arrived, as he had promised, at Wyvern House, and was shown into Sir Horace's consulting-room, where Sir Horace himself and Miss Lorne were awaiting him and keeping close watch before the locked door of a communicating apartment in which sat the six men who had preceded him. He went in and put them all and severally through a rigid examination in quest of any trace of "make-up" or disguise of any sort, examining their badges and the marks on the handcuffs they carried with them to make sure that they bore the sign which he himself had scratched upon them in the privacy of his own room a couple of hours ago.

"No mistake about this lot," he announced, with a smile. "Has anybody else entered or attempted to enter the house?"

"Not a soul," replied Miss Lorne. "I didn't trust anybody to do the watching, Mr. Narkom. I watched myself."

"Good. Where are the jewels? In that safe?"

"No," replied Sir Horace. "They are to be exhibited in the picture gallery for the benefit of the guests at the wedding breakfast to-morrow, and as Miss Wyvern wished to superintend the arrangement of them herself, and there would be no time for that in the morning, she and her sister are in there laying them out at this moment. As I could not prevent that without telling them what we have to dread, I did not protest against it; but if you think it will be safer to return them to the safe after my daughters have gone to bed, Mr. Narkom——"

"Not at all necessary. If our man gets in, their lying there in full view like that will prove a tempting bait, and—well, he'll find there's a hook behind it. I shall be there waiting for him. Now go and join the ladies, you and Miss Lorne, and act as though nothing out of the

common was in the wind. My men and I will stop here, and you had better put out the light and lock us in, so that there's no danger of anybody finding out that we are here. No doubt Miss Wyvern and her sister will go to bed earlier than usual on this particular occasion. Let them do so. Send the servants to bed, too. You and Miss Lorne go to your beds at the same time as the others—or, at least, let them think that you have done so; then come down and let us out."

To this Sir Horace assented, and, taking Miss Lorne with him, went at once to the picture gallery and joined his daughters, with whom they remained until eleven o'clock. Promptly at that hour, however, the house was locked up, the bride-elect and her sister went to bed, the servants having already gone to theirs, and stillness settled down over the darkened house. At the end of a dozen minutes, however, it was faintly disturbed by the sound of slippered feet coming along the passage outside the consulting-room, then a key slipped into the lock, the door was opened, the light switched on, and Sir Horace and Miss Lorne appeared before the eager watchers.

"Now, then, lively, my men, look sharp!" whispered Narkom. "A man to each window and each staircase, so that nobody may go up or down or in or out without dropping into the arms of one of you. Confine your attention to this particular floor, and if you hear anybody coming, lay low until he's within reach, and you can drop on him before he bolts. Is this the door of the picture gallery, Sir Horace?"

"Yes," answered Sir Horace, as he fitted a key to the lock. "But surely you will need more men than you have brought, Mr. Narkom, if it is your intention to guard every window individually, for there are four to this room—see!"

With that he swung open the door, switched on the

electric light, and Narkom fairly blinked at the dazzling sight that confronted him. Three long tables, laden with crystal and silver, cut glass and jewels, and running the full length of the room, flashed and scintillated under the glare of the electric bulbs which encircled the cornice of the gallery and clustered in luminous splendour in the crystal and frosted silver of a huge central chandelier. Spread out on the middle one of these, a dazzle of splintered rainbows, a very plain of living light, lay caskets and cases, boxes and trays, containing those royal gifts of which the newspapers had made so much and the Vanishing Cracksman had sworn to make so few.

Mr. Narkom went over and stood beside the glittering mass, resting his hand against the table and feasting his eyes upon all that opulent splendour.

"God bless my soul! it's superb, it's amazing," he commented. "No wonder the fellow is willing to take risks for a prize like this. You are a splendid temptation, a gorgeous bait, you beauties; but the fish that snaps at you will find that there's a nasty hook underneath in the shape of Maverick Narkom. Never mind the many windows, Sir Horace. Let him come in by them, if that's his plan. I'll never leave these things for one instant between now and the morning. Good-night, Miss Lorne. Go to bed and to sleep. You do the same, Sir Horace. My 'lay' is here!"

With that he stooped and, lifting the long drapery which covered the table and swept down in heavy folds to the floor, crept out of sight under it, and let it drop back into place again.

"Switch off the light and go," he called to them in a low-sunk voice. "Don't worry yourselves, either of you.
