He had been singularly uneasy and watchful all day, listening frequently, with his door slightly ajar, to the downstairs noises of the hotel, sometimes even venturing a few yards down the corridor when the house was more than usually quiet, but retreating quickly to his den at the slightest sound of an approaching footstep. Once he had even penetrated into Captain Ducie's room for a few seconds. "Ah, scélerat! I shall have you yet," he muttered, as he shut himself out of the room after his brief survey.

Now that daylight had faded into dusk, and dusk had deepened into night, his proceedings were still more singular. After finishing his bottle of wine, he proceeded to take off his ordinary outer clothing, and in place of it to induct himself into a tight-fitting suit of some strong dark woven stuff that fitted him like a glove. Round his waist he buckled a belt of dull black leather, and into this belt he stuck a small sheathed dagger. Pendent from the belt was a tiny pouch made of the same material, into which he put some half dozen allumettes, and two small cones of some red material, each of them about four inches in height. This done, his toilette was finished. After a last glance round, he put out the candles, opened the door, and halted on the threshold for a moment or two to listen.

The night was clear and unclouded, and through the staircase window the stars shone brightly in. The corridor was filled with their ghostly light. Midway in it stood the mulatto, black from head to foot, except for his two ferocious eyes that gleamed redly from under his heavy brows like danger signals pointing out the road to death. A pause of a few seconds and then he shut and locked the door of his room--locked it from the outside and put away the key in the tiny pouch by his side.

The quiet starlight seemed to fall away from him affrighted as he moved down the dusky corridor. Now that the door was shut behind him he went on without hesitation or pause. He had only a few paces to go. On reaching the door of number fourteen, he turned the handle, went in, and closed the door softly behind him.

[CHAPTER VI.]

PASTILLE-BURNING.

Rarely had Captain Ducie felt in a pleasanter frame of mind than when he went down to breakfast in the course of the forenoon following the evening on which he had shown Mr. Van Loal and his daughter the Great Mogul Diamond. Several circumstances had combined to render him more than ordinarily cheerful. He had fully made up his mind to propose to Mirpah Van Loal that very day, and he felt little fear that his suit would be rejected. Once married, he would cut his old associations for ever, would probably leave England for several years, and in some remote spot would, with his lovely wife, lead a life such as one sometimes reads of in idylls and romances but rarely sees reduced to practice in this work-a-day world. Mr. Van Loal had appraised the Diamond at a very tolerable sum, and through his influence he would doubtless be able to dispose of it quietly, and in a way that would give rise to no suspicion as to the mode by which it had come into his possession. The proceeds of the sale, judiciously invested, would be productive of an annual income on which it would be possible to live in comfort wherever he might choose to pitch his tent. Lastly, all apprehension as to any results which might possibly have accrued to him from the sudden death of M. Platzoff, and the subsequent events at Bon Repos, had utterly died away. He had got by this time to feel as if the Diamond were as much his own as though it had been given to him or handed down to him as a family heirloom. If any uncomfortable thought connected with the death of Platzoff and his appropriation of the Diamond ever crossed his mind, it was dismissed with ignominy, like a poor relation, almost as soon as it made itself known. Captain Ducie was not a man to let his conscience trouble him whenever it wished to question him respecting any transaction the results of which had proved prosperous to himself. In such cases he bade it begone, turning it out by main force, and shutting the door in its face. But whenever it stole in and began to reproach him for his conduct in any little affair that in its results had proved disastrous either socially or pecuniarily, then did Edmund Ducie bow his head in all humility before the veiled monitress, and cry mea culpa, and bewail his naughtiness with many inward groans, and promise to amend his ways in time to come. But it may be doubted whether in the latter case his regret did not arise less from having done that which was wrong, than because the wrong had proved unsuccessful in compassing the ends for which it was done.

Be that as it may, Captain Ducie's conscience did not seem to trouble him much as he came downstairs this pleasant autumn morning, humming an air from the Trovatore, and giving the last finishing touches to his filbert-shaped nails. He rang the bell for breakfast, and turned over, half contemptuously, the selection of newspapers on the side table.

"Has Mr. Van Loal come down to breakfast yet, do you know?" he asked when the waiter re-entered the room.

"I will ascertain, sir, and let you know."
