"On Monday evening, sir," he said, "about eight o'clock, his Excellency and the two secretaries were dining downstairs, and matters had, thus far, gone on with the same routine as was observed every preceding day. The workmen quitted work at six o'clock. The three gentlemen went out for a drive as soon as everything was locked up, and came in again at a quarter to eight. They did not change their clothes for dinner, so there was no occasion to search them, as no one had gone upstairs since they had descended soon after six. They had barely started dinner when some one called at the front door, and I was sent for. The door bell, I may explain, was always answered by one of the house servants, and he, if necessary, admitted any person who came, closing the door; but the visitor had to be examined by the policeman stationed in the passage before he was permitted to come any further. On this occasion I went out and found three gentlemen standing there. They were Turks, as could be easily seen by their attire, and appeared to be persons of some consequence." "What do you mean by the words 'their attire'?" interrupted Brett. "Were they dressed in European clothes or in regular Turkish garments?" "Oh," said the inspector, "I only meant that they wore fezzes; otherwise they were quite accurately dressed in frock coats and the rest, but they were unmistakably Turks by their appearance. Two of them could speak no English, and the third, who acted as the leader of the party, first of all addressed me in French. Finding I did not understand him, he used very broken, but fairly intelligible, English. What he wanted was to be taken at once to his Excellency, Mehemet Ali Pasha. I said that his Excellency was dining and that perhaps he had better call in the morning, but he replied that his business was very urgent, and he could not wait. He made me understand that if I sent in the cards of himself and his companions they would certainly be admitted at once. I did not see any harm in this, so I took the three cards and gave them to Hussein, who was crossing the hall at the moment." "As the cards were printed in Turkish characters you could not, of course, tell what the names were," said Brett. A look of blank astonishment crossed the inspector's face as he replied: "That is a good guess, but it is so. The hieroglyphics on the piece of pasteboard were worse than Greek. However, Hussein glanced at them. He appeared to be surprised; he went into the dining-room, returning with the message that the gentlemen were to be admitted. Of course I had nothing else to do but to let them in, which I did, accompanying them myself to the door of the dining-room, and making sure, before the door was closed, that their presence was expected." "How did you do that?" said Brett.
