"Did your brother say why the diamonds were brought to this country in the first instance?"

"Yes; the Sultan and his advisers seemed to think the work of cutting them could be performed more safely and expeditiously here than anywhere else. Even the Turk has a high regard for the manner in which law and order are maintained in Britain. Yet the sequel has shown that the diamonds and their guardians were perhaps in greater danger here than they would have been in Constantinople."

"Was that the only reason?" said Brett, who had apparently made up his mind with reference to the pattern of the carpet, and was now gazing into the bright fire which danced merrily in the grate, for the day though fine was chilly.

The girl wrinkled her brows in thought before she answered: "I think I do remember Jack saying that he believed there was some State business mixed up in the affair, but I am quite sure he did not know the exact facts himself."

"Can you recollect any of the special precautions taken to protect the gems? Your brother may have mentioned some details in conversation, you know."

"Oh, I think I know all about them. In the first instance, the house at Albert Gate had previously been tenanted by a rich banker, and it was well defended by all ordinary means against the attacks of ordinary burglars. But, in addition to this, before the diamonds left the safe at the Bank of England, the building was practically torn to pieces inside by workmen acting under the direction of the Commissioner of Police. It was absolutely impossible for anyone to enter except through the front door, unless they flew out of the second storey window. Servants and workmen, like everybody else, had to use this door alone, as the windows and doors in the bas.e.m.e.nt had all been bricked up. Inside the entrance-hall there were always twelve policemen, and an inspector in charge.

"Every one who left the house was searched by the inspector on duty, and Jack used to say that he was very glad he invariably insisted upon this examination, although the police were at first disinclined to meet his wishes in the matter, he being, so to speak, their direct superior for the time. Beneath the entrance-hall were rooms occupied by several Turkish and other servants. Mehemet Ali himself, in the presence of his secretaries, used to open the door leading to the suite of apartments in which the diamond cutters worked, and two of the Turkish gentlemen would remain there all day until the men left in the evening. The Envoy and both secretaries used to meet Jack when he visited the place, and for the last three weeks he had nothing to do but see the diamonds, count them, drink an excellent cup of coffee, and smoke a wonderful cigarette, made of some special Turkish tobacco, cultivated and prepared only for the Imperial household."

"Ah!" sighed Brett, with a note of almost unconscious envy in his voice.

He knew exactly what that coffee and those cigarettes would be like. "I beg your pardon," he went on, perceiving that Miss Talbot did not understand his exclamation. "Will you tell me as nearly as you can the occurrences of Monday evening?"

"They were simple enough," said the girl. "My brother dined at home. We had one or two guests, and were all in the drawing room about 10 15, when a note came for him from Mehemet Ali. I know exactly what was in it. I looked over his shoulder whilst he read it. The words were: 'I wish to see you to-night on important business. Come, if possible, at once.' I have to tell you that it was in French, but this is an exact translation."

"Your brother was quite sure that it was from Mehemet Ali himself?" said Brett.

"Quite sure," was the reply. "He knew his handwriting well, having had several communications from him during the progress of the business."

"Did your brother leave the house immediately?" asked Brett.

"That instant. He went downstairs, put on his overcoat and hat, and got into a cab with the messenger who brought the note."

"Do you know who this messenger was?"

"One of the policemen on duty in the house itself."

A slight pause ensued, and Brett was about to take his departure, having no further questions to ask at the moment, when some one was heard hastily ascending the stairs, talking to a companion as he advanced.

"This is my uncle," exclaimed Miss Talbot, rising to go to the door.

Before she could reach it an elderly gentleman entered, bearing upon him all those distinguishing tokens that stamp a man as a retired major-general.

He exclaimed impetuously--

"I have brought a gentleman from Scotland Yard, my dear." Then he caught sight of Brett. "Who is this?"

Edith was about to explain, when another man entered--a strongly-built, bullet-headed man, with keen eyes and firm mouth, and a curious suggestion in his appearance of having combined pugilism with process-serving as a professional means of existence. His face extended into a smile when his eyes fell upon the barrister.

"Ah, Mr. Brett," he cried. "Now we have something to do that is up to your mark. You are on the spot first, as usual, but this time I can honestly say that I am glad to see you."

Sir Hubert Fitzjames glanced in astonishment from his niece to the barrister. He could find nothing better to say than--

"This, my dear, is Mr. Winter, of Scotland Yard."

CHAPTER III

WHAT THE POLICE SAW

Brett promptly cleared the situation by explaining to Sir Hubert, in a few words, the reason for his unexpected presence, and when the Major-General learnt the name of the distinguished personage who had sent Lord Fairholme to the barrister he expressed a ready acquiescence in the desire to utilise his services. Nor was the effect of such a notable introduction lost on Mr. Winter, whose earlier knowledge of the barrister's remarkable achievements in unravelling the tangled skein of criminal investigation was now supplemented by a certain amount of awe for a man who commanded the confidence of His Majesty's Government.

"Well," said Sir Hubert Fitzjames, with the brisk animation of one accustomed to utter commands that must be instantly obeyed, "we will now proceed to business."

For the moment no one spoke. The Scotland Yard detective evidently wished his distinguished colleague to take the lead. No sooner did Brett perceive this than he rose, bowed politely to Miss Talbot and her uncle, and said--

"The first thing to do is to trace the whereabouts of Mr. Talbot, and this should be a comparatively easy task. The other features of this strange occurrence impress me as highly complex, but it is far too early a stage in the investigation to permit any definite opinion being expressed at this moment."

Every one seemed to be surprised by Brett's att.i.tude.

"Where are you going to, sir?" asked Mr. Winter.

"That depends largely upon you," was the smiling reply. "If you come with me we will go direct to Albert Gate, but if you decide to prosecute further inquiries here, I will await your arrival at my flat."

"That is as much as saying that there are no facts worth inquiring into to be learnt here?"

"Exactly so. Miss Talbot has told me all that is material to our purpose. Her brother was unexpectedly sent for after dinner on Monday night, and left the house hurriedly, without affording any clue to his subsequent proceedings beyond that contained in a brief note sent to him by Mehemet Ali Pasha. Indeed, it was impossible for him to afford any explanation, as he himself was quite unprepared for the summons.

Meanwhile, every moment lost in the endeavour to follow up his movements is precious time wasted."

The barrister's manner, no less than his words, impressed Mr. Winter so greatly that he too rose from the seat which he had occupied, with the intention of conducting a long and careful examination of each member of the household.

"Then I will come with you at once," he said.

"Oh," cried the Major-General, "I understood you to say as we came here that there were many questions which required immediate inquiry in this house, on the principle that the movements of the missing man should be minutely traced from the very commencement."

Mr. Winter looked somewhat confused, but Edith Talbot broke in--

"I think, uncle dear, it would be well to defer to Mr. Brett's judgment."

"Do you really believe," she said, turning to the barrister, "that you will soon be able to find my brother?"

"I am quite sure of it," he replied, and the conviction in his tone astonished the professional detective, whilst it carried a message of hope to the others. Even Sir Hubert, for some reason which he could not explain, suddenly experienced a strong sense of confidence in this reserved, distinguished-looking man. He stepped forward eagerly and held out his hand, saying--

"Then we will not detain you, Mr. Brett. Act as you think fit in all things, but do let us have all possible information at the earliest moment. The suspense and uncertainty of the present position of affairs are terribly trying to my niece and myself." The old soldier spoke with dignity and composure, but his lips quivered, and the anguish in his eyes was pitiful.

Brett and Mr. Winter quitted the house; they hailed a hansom, and drove rapidly towards Albert Gate.

"Do you know," said the man from Scotland Yard, breaking in on his companion's reverie, "you surprised me by what you said just now, Mr.

Brett?"

"I thought you were too old a hand to be surprised at anything," was the reply.

"Oh, come now, you know well enough what I mean. You said you thought it would be a comparatively simple matter to find Mr. Talbot, whilst the other features of the crime are very complex. Now the affair, thus far, impresses me as being the exact opposite to that statement. The crime is simple enough. A clever gang of thieves get into the place by working some particularly cool and daring confidence game. They don't hesitate at murder to cover up their tracks, and they make away with the plunder under the very noses of the police. All this may be smart and up-to-date in its methods, but it is not unusual. The difficult question to my mind is, what have they done with Mr. Talbot, and how did they succeed in fooling him so completely as to make him what one might almost call a party to the transaction?"
