'Ah, who can say? It is possible that the matter may end here, and we shall never know, but in my own opinion this Helen Vaughan, or Mrs. Herbert, is only the beginning. She will come back to London, Austin; depend on it, she will come back, and we shall hear more about her then. I doubt it will be very pleasant news.'

Lord Argentine was a great favourite in London Society. At twenty he had been a poor man, decked with the surname of an illustrious family, but forced to earn a livelihood as best he could, and the most speculative of money-lenders would not have entrusted him with fifty pounds on the chance of his ever changing his name for a title, and his poverty for a great fortune. His father had been near enough to the fountain of good things to secure one of the family livings, but the son, even if he had taken orders, would scarcely have obtained so much as this, and moreover felt no vocation for the ecclesiastical estate. Thus he fronted the world with no better armour than the bachelor's gown and the wits of a younger son's grandson, with which equipment he contrived in some way to make a very tolerable fight of it. At twenty-five Mr. Charles Aubernon saw himself still a man of struggles and of warfare with the world, but out of the seven who stood before him and the high places of his family three only remained. These three, however, were 'good lives,' but yet not proof against the Zulu assegais and typhoid fever, and so one morning Aubernon woke up and found himself Lord Argentine, a man of thirty who had faced the difficulties of existence, and had conquered. The situation amused him immensely, and he resolved that riches should be as pleasant to him as poverty had always been. Argentine, after some little consideration, came to the conclusion that dining, regarded as a fine art, was perhaps the most amusing pursuit open to fallen humanity, and thus his dinners became famous in London, and an invitation to his table a thing covetously desired. After ten years of lordship and dinners Argentine still declined to be jaded, still persisted in enjoying life, and by a kind of infection had become recognized as the cause of joy in others, in short, as the best of company. His sudden and tragical death therefore caused a wide and deep sensation. People could scarcely believe it, even though the newspaper was before their eyes, and the cry of 'Mysterious Death of a Nobleman' came ringing up from the street. But there stood the brief paragraph: 'Lord Argentine was found dead this morning by his valet under distressing circumstances. It is stated that there can be no doubt that his lordship committed suicide, though no motive can be assigned for the act. The deceased nobleman was widely known in society, and much liked for his genial manner and sumptuous hospitality. He is succeeded by,' etc., etc.

By slow degrees the details came to light, but the case still remained a mystery. The chief witness at the inquest was the deceased's valet, who said that the night before his death Lord Argentine had dined with a lady of good position, whose name was suppressed in the newspaper reports. At about eleven o'clock Lord Argentine had returned, and informed his man that he should not require his services till the next morning. A little later the valet had occasion to cross the hall and was somewhat astonished to see his master quietly letting himself out at the front door. He had taken off his evening clothes, and was dressed in a Norfolk coat and knickerbockers, and wore a low brown hat. The valet had no reason to suppose that Lord Argentine had seen him, and though his master rarely kept late hours, thought little of the occurrence till the next morning, when he knocked at the bedroom door at a quarter to nine as usual. He received no answer, and, after knocking two or three times, entered the room, and saw Lord Argentine's body leaning forward at an angle from the bottom of the bed. He found that his master had tied a cord securely to one of the short bed-posts, and, after making a running noose and slipping it round his neck, the unfortunate man must have resolutely fallen forward, to die by slow strangulation. He was dressed in the light suit in which the valet had seen him go out, and the doctor who was summoned pronounced that life had been extinct for more than four hours. All papers, letters, and so forth seemed in perfect order, and nothing was discovered which pointed in the most remote way to any scandal either great or small. Here the evidence ended; nothing more could be discovered. Several persons had been present at the dinner-party at which Lord Argentine had assisted, and to all these he seemed in his usual genial spirits. The valet, indeed, said he thought his master appeared a little excited when he came home, but confessed that the alteration in his manner was very slight, hardly noticeable, indeed. It seemed hopeless to seek for any clue, and the suggestion that Lord Argentine had been suddenly attacked by acute suicidal mania was generally accepted.

It was otherwise, however, when within three weeks, three more gentlemen, one of them a noble man, and the two others men of good position and ample means, perished miserably in the almost precisely the same manner. Lord Swanleigh was found one morning in his dressing-room, hanging from a peg affixed to the wall, and Mr. Collier-Stuart and Mr. Herries had chosen to die as Lord Argentine. There was no explanation in either case; a few bald facts; a living man in the evening, and a body with a black swollen face in the morning. The police had been forced to confess themselves powerless to arrest or to explain the sordid murders of Whitechapel; but before the horrible suicides of Piccadilly and Mayfair they were dumbfoundered, for not even the mere ferocity which did duty as an explanation of the crimes of the East End, could be of service in the West. Each of these men who had resolved to die a tortured shameful death was rich, prosperous, and to all appearances in love with the world, and not the acutest research should ferret out any shadow of a lurking motive in either case. There was a horror in the air, and men looked at one another's faces when they met, each wondering whether the other was to be the victim of the fifth nameless tragedy. Journalists sought in vain for their scrapbooks for materials whereof to concoct reminiscent articles; and the morning paper was unfolded in many a house with a feeling of awe; no man knew when or where the next blow would light.

A short while after the last of these terrible events, Austin came to see Mr. Villiers. He was curious to know whether Villiers had succeeded in discovering any fresh traces of Mrs. Herbert, either through Clarke or by other sources, and he asked the question soon after he had sat down.

'No,' said Villiers, 'I wrote to Clarke, but he remains obdurate, and I have tried other channels, but without any result. I can't find out what became of Helen Vaughan after she left Paul Street, but I think she must have gone abroad. But to tell the truth, Austin, I haven't paid much attention to the matter for the last few weeks; I knew poor Herries intimately, and his terrible death has been a great shock to me, a great shock.'

'I can well believe it,' answered Austin gravely, 'you know Argentine was a friend of mine. If I remember rightly, we were speaking of him that day you came to my rooms.'

'Yes; it was in connection with that house in Ashley Street, Mrs. Beaumont's house. You said something about Argentine's dining there.'

'Quite so. Of course you know it was there Argentine dined the night before-before his death.'

'No, I had not heard that.'

'Oh, yes; the name was kept out of the papers to spare Mrs. Beaumont. Argentine was a great favourite of hers, and it is said she was in a terrible state for sometime after.'
