"I'll just stay and see her come to, mum. I won't do her a morsel of harm, mum. Sometimes they faints at the very fust sight of such as we; but we has to bear it. A little more air, if you could, mum;—and just dash the water on in drops like. They feels a drop more than they would a bucketful,—and then when they comes to they hasn't to change theirselves."

Bunfit's advice, founded on much experience, was good, and Lizzie gradually came to herself and opened her eyes. She immediately clutched at her breast, feeling for her key. She found it unmoved, but before her finger had recognised the touch, her quick mind had told her how wrong the movement had been. It had been lost upon Mrs. Carbuncle, but not on Mr. Bunfit. He did not at once think that she had the diamonds in her desk; but he felt almost sure that there was something in her possession,—probably some document,—which, if found, would place him on the track of the diamonds. But he could not compel a search. "Your ladyship'll soon be better," said Bunfit graciously. Lizzie endeavoured to smile as she expressed her assent to this proposition. "As I was a saying to the elder lady—"

"Saying to who, sir?" exclaimed Mrs. Carbuncle, rising up in wrath. "Elder, indeed!"

"As I was a venturing to explain, these fits of fainting come often in our way. Thieves, mum,—that is, the regulars,—don't mind us a bit, and the women is more hardeneder than the men; but when we has to speak to a lady, it is so often that she goes off like that! I've known 'em do it just at being looked at."

"Don't you think, sir, that you'd better leave us now?" said Mrs. Carbuncle.

"Indeed you had," said Lizzie. "I'm fit for nothing just at present."

"We won't disturb your ladyship the least in life," said Mr. Bunfit, "if you'll only just let us have your keys. Your servant can be with us, and we won't move one tittle of anything." But Lizzie, though she was still suffering that ineffable sickness which always accompanies and follows a real fainting-fit, would not surrender her keys. Already had an excuse for not doing so occurred to her. But for a while she seemed to hesitate. "I don't demand it, Lady Eustace," said Mr. Bunfit, "but if you'll allow me to say so, I do think it will look better for your ladyship."

"I can take no step without consulting my cousin, Mr. Greystock," said Lizzie; and having thought of this she adhered to it. The detective supplied her with many reasons for giving up her keys, alleging that it would do no harm, and that her refusal would create infinite suspicions. But Lizzie had formed her answer and stuck to it. She always consulted her cousin, and always acted upon his advice. He had already cautioned her not to take any steps without his sanction. She would do nothing till he consented. If Mr. Bunfit would see Mr. Greystock, and if Mr. Greystock would come to her and tell her to submit,—she would submit. Ill as she was, she could be obstinate, and Bunfit left the house without having been able to finger that key which he felt sure that Lady Eustace carried somewhere on her person.

As he walked back to his own quarters in Scotland Yard, Bunfit was by no means dissatisfied with his morning's work. He had not expected to find anything with Lady Eustace, and, when she fainted, had not hoped to be allowed to search. But he was now sure that her ladyship was possessed, at any rate, of some guilty knowledge. Bunfit was one of those who, almost from the first, had believed that the box was empty when taken out of the hotel. "Stones like them must turn up more or less," was Bunfit's great argument. That the police should already have found the stones themselves was not perhaps probable; but had any ordinary thieves had them in their hands, they could not have been passed on without leaving a trace behind them. It was his opinion that the box had been opened and the door cut by the instrumentality and concurrence of Lord George de Bruce Carruthers,—with the assistance of some well-skilled mechanical thief. Nothing could be made out of the tall footman;—indeed, the tall footman had already been set at liberty, although he was known to have evil associates; and the tall footman was now loud in demanding compensation for the injury done to him. Many believed that the tall footman had been concerned in the matter,—many, that is, among the experienced craftsmen of the police force. Bunfit thought otherwise. Bunfit believed that the diamonds were now either in the possession of Lord George or of Harter and Benjamin, that they had been handed over to Lord George to save them from Messrs. Camperdown and the lawsuit, and that Lord George and the lady were lovers. The lady's conduct at their last interview, her fit of fainting, and her clutching for the key, all confirmed Bunfit in his opinion. But unfortunately for Bunfit he was almost alone in his opinion. There were men in the force,—high in their profession as detectives,—who avowed that certainly two very experienced and well-known thieves had been concerned in the business. That a certain Mr. Smiler had been there,—a gentleman for whom the whole police of London entertained a feeling which approached to veneration, and that most diminutive of full-grown thieves, Billy Cann,—most diminutive but at the same time most expert,—was not doubted by some minds which were apt to doubt till conviction had become certainty. The traveller who had left the Scotch train at Dumfries had been a very small man, and it was a known fact that Mr. Smiler had left London by train, from the Euston Square station, on the day before that on which Lizzie and her party had reached Carlisle. If it were so, if Mr. Smiler and Billy Cann had both been at work at the hotel, then,—so argued they who opposed the Bunfit theory,—it was hardly conceivable that the robbery should have been arranged by Lord George. According to the Bunfit theory, the only thing needed by the conspirators had been that the diamonds should be handed over by Lady Eustace to Lord George in such a way as to escape suspicion that such transfer had been made. This might have been done with very little trouble,—by simply leaving the box empty, with the key in it. The door of the bedroom had been opened by skilful professional men, and the box had been forced by the use of tools which none but professional gentlemen would possess. Was it probable that Lord George would have committed himself with such men, and incurred the very heavy expense of paying for their services, when he was,—according to the Bunfit theory,—able to get at the diamonds without any such trouble, danger, and expenditure? There was a young detective in the force, very clever,—almost too clever, and certainly a little too fast,—Gager by name, who declared that the Bunfit theory "warn't on the cards." According to Gager's information, Smiler was at this moment a broken-hearted man,—ranging between mad indignation and suicidal despondency, because he had been treated with treachery in some direction. Mr. Gager was as fully convinced as Bunfit that the diamonds had not been in the box. There was bitter, raging, heart-breaking disappointment about the diamonds in more quarters than one. That there had been a double robbery Gager was quite sure;—or rather a robbery in which two sets of thieves had been concerned, and in which one set had been duped by the other set. In this affair Mr. Smiler and poor little Billy Cann had been the dupes. So far Gager's mind had arrived at certainty. But then how had they been duped, and who had duped them? And who had employed them? Such a robbery would hardly have been arranged and executed except on commission. Even Mr. Smiler would not have burthened himself with such diamonds without knowing what to do with them, and what he should get for them. That they were intended ultimately for the hands of Messrs. Harter and Benjamin, Gager almost believed. And Gager was inclined to think that Messrs. Harter and Benjamin,—or rather Mr. Benjamin, for Mr. Harter himself was almost too old for work requiring so very great mental activity,—that Mr. Benjamin, fearing the honesty of his executive officer Mr. Smiler, had been splendidly treacherous to his subordinate. Gager had not quite completed his theory; but he was very firm on one great point,—that the thieves at Carlisle had been genuine thieves, thinking that they were stealing the diamonds, and finding their mistake out when the box had been opened by them under the bridge. "Who have 'em, then?" asked Bunfit of his younger brother, in a disparaging whisper.

"Well; yes; who 'ave 'em? It's easy to say, who 'ave 'em? Suppose 'e 'ave 'em." The "he" alluded to by Gager was Lord George de Bruce Carruthers. "But laws, Bunfit, they're gone—weeks ago. You know that, Bunfit." This had occurred before the intended search among poor Lizzie's boxes, but Bunfit's theory had not been shaken. Bunfit could see all round his own theory. It was whole, and the motives as well as the operations of the persons concerned were explained by it. But the Gager theory only went to show what had not been done, and offered no explanation of the accomplished scheme. Then Bunfit went a little further in his theory, not disdaining to accept something from Gager. Perhaps Lord George had engaged these men, and had afterwards found it practicable to get the diamonds without their assistance. On one great point all concerned in the inquiry were in unison,—that the diamonds had not been in the box when it was carried out of the bedroom at Carlisle. The great point of difference consisted in this, that whereas Gager was sure that the robbery when committed had been genuine, Bunfit was of opinion that the box had been first opened, and then taken out of the hotel in order that the police might be put on a wrong track.
