What it all amounted to, told disjointedly, was this: Since Monny had had an inspiration the day after our arrival in Cairo, to give Rachel Guest a lot of her new unworn clothes, Rachel had become quite girlish and "flighty." She had lost her puritan primness, and behaved more in accordance with her slanting eyes than with her bringing up. She giggled like a schoolgirl rather than a schoolmistress, tried to make herself look young, and copied Monny in the way she tilted her hat and dressed her hair. No harm in this; but it had seemed to Biddy that Rachel deliberately incited the girl to do things which "Antoun" disapproved. Brigit fancied that Bedr's influence had been at work, for knowing as he did that "Antoun" would gladly have given him marching orders, he took pleasure in thwarting his superior when he could do so with safety. Bedr had been clever in enlisting the girls' sympathy for his soul. As for Biddy, she had disliked him from the first, and imagined that he had tacked himself onto our party as a spy, upon the receipt of orders from America, he having learned most of his English there. The idea appeared so far-fetched that she had abandoned it. Now, however, it was again hovering at the back of her mind.

Bedr had told Rachel stories of the fascination of hasheesh smoking, and had said that no stranger knew Cairo who did not visit one of the "best houses" where hasheesh, though forbidden, was still secretly smoked. He had assured her that there were several which were "perfectly respectable," even for the "nicest ladies and gentlemen;" and Rachel, probably at his suggestion, had tried to persuade Monny to make the expedition. Monny had mentioned it to "Antoun," in the presence of everybody; and as Rachel and Bedr had looked guilty, Biddy guessed that they had wished to keep the plan a secret.

"Antoun" had perhaps too brusquely vetoed the idea. He said that there were no such houses, which could be visited by ladies, and that it was absurd to think of going. That word "absurd" stung Monny. She began to protest that Bedr knew Cairo as well as Antoun did, and was as likely to be right. "I don't see why we shouldn't go, if others do," she persisted, "and I've always longed to know what a hasheesh dream was like, ever since I read De Quincey. A little, just once, could do us no harm, and Rachel says——"

But what Rachel had said was evidently not for publication. Miss Guest stopped her with a hand on hers, and a "Dear Monny, please don't let us think of it any more, if Antoun Effendi disapproves. Maybe it was a silly idea, and we've plenty of amusing things to do every minute."

Monny was apparently contented to let the idea slip, and Brigit had thought that, in the excitement of getting ready for the ball, she and Rachel had really forgotten it. Then, before writing me, she had overheard Rachel say to her friend, "It's for twelve o'clock sharp." And Monny had answered, "Won't it be great! Does Bedr think——" But she had stopped short at sight of Brigit.

Even this did not suggest to Biddy a visit to a "hasheesh den," for various other plans had been broached and discouraged by "Antoun." She did not feel that, as she was not supposed to know his real status, she could go "blabbing" to him; and fearing that mischief was on foot, she had wished for me. When I didn't arrive, she soothed herself by reflecting that, after all, she need only keep a sharp watch over Monny when midnight drew near. None of the party intended to dance, and so it would be easy, Brigit thought, to "have an eye upon the girls."

Monny had bought Oriental costumes for herself and Rachel. They were rather conspicuous, luckily for Biddy's plan, for among the many gorgeous dresses in the Casino she had no difficulty in tracking those two. Until half past eleven, she told herself, she need not be on the alert every instant; but therein had lain her mistake. Sir Marcus Lark had appeared, dressed (more or less) as a Roman officer of the Occupation days, he having heard Mrs. East remark that, "whatever anybody said, it was her favourite period." The lady, of course, had not missed such an opportunity to appear as Cleopatra. She had brought a costume with her from New York; and while Biddy "lost herself" in watching the effect of this magnificence on Sir Marcus, the girls vanished.

Without alarming Mrs. East, Brigit had begun to search. She asked everybody she knew in the ballroom if the girls had gone out, and inquired in the cloakroom; but the two had been seen by nobody. It was as if they had melted into air; and Brigit began to suspect that they must have covered up their brilliant dresses with dominoes smuggled into the Casino. Willis Bailey was at the ball, but he had developed a flirtation with Miss Guest, and Biddy felt that he was not to be trusted as a confidant. Perhaps, too, he had helped the girls to disappear. It seemed cruel to frighten Mrs. East, when the scheme, whatever it was, might be no more than an innocent freak; so Biddy said nothing to Queen Cleopatra or her Roman attendant. She slipped across the garden to the hotel, and sent an Arab messenger off in a taxi with a note to the address "Antoun" had told her would find him. In less than an hour he arrived, and when he had listened to her account of what had happened, he said after a minute's reflection that the ladies had almost surely gone with Bedr to some hasheesh den, or a place masquerading as such. "Antoun" consoled Biddy as well as he could, by saying that no harm would come to Miss Gilder or Miss Guest. Bedr would know too well on which side his bread was buttered to take his clients where insult or danger could reach them. Off "Antoun" went to look for the missing ones though, and assured Biddy that she should have news as soon as possible.

It was not till three o'clock that she had begun to be very anxious, and had disturbed the harmony of Sir Marcus Lark's duet with Mrs. East. Even then she would not have spoken had she not feared that the ball would break up, and there would be no man to appeal to!

Sir Marcus had been inclined to smile at the notion of danger; but he, like Anthony Fenton, was ignorant of any private qualms which troubled Brigit O'Brien. She could not tell him who she was, and that she considered herself far from being a "mascot" to her fellow-travellers. If she had told, and added that she feared enemies who might for certain reasons make a mistake in Monny's identity, he would have laughed his hearty laugh, and said that such melodramatic things didn't happen, even in Egypt.
