The trio proceeded along old Bond Street.  Quentin Gray regarded the story of Kazmah as a very poor lie devised on the spur of the moment.  If he had been less infatuated, his natural sense of dignity must have dictated an offer to release Mrs. Irvin from her engagement.  But jealousy stimulates the worst instincts and destroys the best.  He was determined to attach himself as closely as the old Man of the Sea attached himself to Es-Sindibad, in order that the lie might be unmasked.  Mrs. Irvin’s palpable embarrassment and nervousness he ascribed to her perception of his design.

A group of shop girls and others waiting for buses rendered it impossible for the three to keep abreast, and Gray, falling to the rear, stepped upon the foot of a little man who was walking close behind them.

“Sorry, sir,” said the man, suppressing an exclamation of pain—­for the fault had been Gray’s.

Gray muttered an ungenerous acknowledgment, all anxiety to regain the side of Mrs. Irvin; for she seemed to be speaking rapidly and excitedly to Sir Lucien.

He recovered his place as the two turned in at a lighted doorway.  Upon the wall was a bronze plate bearing the inscription: 

    Kazmah
    Second Floor

Gray fully expected Mrs. Irvin to suggest that he should return later.  But without a word she began to ascend the stairs.  Gray followed, Sir Lucien standing aside to give him precedence.  On the second floor was a door painted in Oriental fashion.  It possessed neither bell nor knocker, but as one stepped upon the threshold this door opened noiselessly as if dumbly inviting the visitor to enter the square apartment discovered.  This apartment was richly furnished in the Arab manner, and lighted by a fine brass lamp swung upon chains from the painted ceiling.  The intricate perforations of the lamp were inset with colored glass, and the result was a subdued and warm illumination.  Odd-looking oriental vessels, long-necked jars, jugs with tenuous spouts and squat bowls possessing engraved and figured covers emerged from the shadows of niches.  A low divan with gaily colored mattresses extended from the door around one corner of the room where it terminated beside a kind of mushrabiyeh cabinet or cupboard.  Beyond this cabinet was a long, low counter laden with statuettes of Nile gods, amulets, mummy-beads and little stoppered flasks of blue enamel ware.  There were two glass cases filled with other strange-looking antiquities.  A faint perfume was perceptible.

Sir Lucien entering last of the party, the door closed behind him, and from the cabinet on the right of the divan a young Egyptian stepped out.  He wore the customary white robe, red sash and red slippers, and a tarbush, the little scarlet cap commonly called a fez, was set upon his head.  He walked to a door on the left of the counter, and slid it noiselessly open.  Bowing gravely, “The Sheikh el Kazmah awaits,” he said, speaking with the soft intonation of a native of Upper Egypt.
