The boy Mohammed was proud and very happy. He had not been in a motor-car, for he had not got to Touggourt; but it was glorious to have travelled far north, almost out of the dunes, and not only to have seen giant women in short skirts with bare legs, but not to be afraid of them, as the grown-up Arabs were. The giant women were Hamish and Angus, and it was a great thing to know them, and to be able to explain them to his father's men from the ZaouÏa.

He was a handsome little fellow, with a face no darker than old ivory, and heavily lashed, expressive eyes, like those which looked over the marabout's mask. His dress was that of a miniature man; a white silk burnous, embroidered with gold, over a pale blue vest, stitched in many colours; a splendid red cloak, whose embroidery of stiff gold stood out like a bas-relief; a turban and chechia of thin white muslin; and red-legged boots finer than those of the Spahis. Though he was but eleven years old, and had travelled hard for days, he sat his horse with a princely air, worthy the son of a desert potentate; and like a prince he received the homage of the marabout's men who rushed to him with guttural cries, kissing the toes of his boots, in their short stirrups, and fighting for an end of his cloak to touch with their lips. He did not know that he had been "kidnapped." His impression was that he had deigned to favour a rather agreeable Roumi with his company. Now he was returning to his own people, and would bid his Roumi friend good-bye with the cordiality of one gentleman to another, though with a certain royal condescension fitted to the difference in their positions.

Nevill was in wild spirits, though pale with heat and fatigue. He had nothing to say of himself, but much of his aunt and of the boy Mohammed. "Ripping little chap," he exclaimed, when Saidee had gone indoors. "You never saw such pluck. He'd die sooner than admit he was tired. I shall be quite sorry to part from him. He was jolly good company, a sort of living book of Arab history. And what do you say to our surprise,—the twins? My aunt sent them off at the same time with the telegram, but of course they put in an appearance much later. They caught me up this morning, riding like devils on racing camels, with one guide. No horses could be got big enough for them. They've frightened every Arab they've met—but they're used to that and vain of it. They've got rifles—and bagpipes too, for all I know. They're capable of them."

"I can't tell you how glad I am to see you, Wings," said Stephen, "and only a little less glad to see those big fellows with their brave faces." Then he mentioned to Nevill the apparition of that mysterious caravan which had appeared, and vanished. Also he described the behaviour of the ZaouÏa men when they had looked south, instead of north.

"Oh, that's all right, I'll bet," exclaimed Nevill, exuberant with the joy of success, and in the hope of coolness, food and rest. "Might have been any old caravan, on its own business—nothing to do with us. That's the most likely thing. But if the marabout's mixed up with it, I should say it's only because he couldn't bear to stop at home and wait in suspense, and I don't blame him, now I've made acquaintance with the kid. He'd be too proud to parade his anxiety under our noses, but would lurk in the distance, out of our sight, he probably flatters himself, to welcome his son, and take him back to Oued Tolga. Not unnatural—and in spite of all, I can't help being a little sorry for the man. We've humiliated and got the better of him, because we happen to have his secret. It's a bit like draining a chap's blood, and then challenging him to fight. He's got all he can expect now, in receiving the child back and if I can judge him by myself, he'll be so happy, that he'll be only too thankful to see our backs for the last time."

"He might feel safer to stick a knife in them."

"Oh, lord, I'm too hot to worry!" laughed Nevill. "Let's bid the boy Godspeed, or the Mussulman equivalent, which is a lot more elaborate, and then turn our thoughts to a bath of sorts and a dinner of sorts. I think Providence has been good to us so far, and we can afford to trust It. I'm sure Miss Ray would agree with me there." And Nevill glanced with kind blue eyes toward the shut door behind which Victoria had disappeared with her sister.

When at last the little Mohammed had been despatched with great ceremony of politeness, as well as a present of Stephen's gold watch, the two Englishmen watched him fade out of sight with his cavalcade of men from the ZaouÏa, and saw that nothing moved in the southern distance.

"All's right with the world, and now for a wash and food!" cried Nevill, turning in with a sigh of relief at the gate of the bordj. "But oh, by the way—Hamish has got a letter for you—or is it Angus? Anyhow, it's from my fairy aunt, which I would envy you, if she hadn't sent me on something better—a post-card from Tlemcen. My tyrant goddess thinks letters likely to give undue encouragement, but once in a while she sheds the light of a post-card on me. Small favours thankfully received—from that source!"

Inside the courtyard, the Highlanders were watching the three Arabs who had travelled with them and their master, attending to the horses and camels. These newcomers were being shown the ropes by the one servant of the bordj, Stephen's men helping with grave good-nature. They all seemed very friendly together, as is the way of Arabs, unless they inhabit rival districts.

Hamish had the letter, and gave it to Stephen, who retired a few steps to read it, and Nevill, seeing that the twins left all work to the Arabs, ordered them to put his luggage into the musty-smelling room which he was to share with Stephen, and to get him some kind of bath, if it were only a tin pan.

Stephen did not listen to these directions, nor did he hear or see anything that went on in the courtyard, for the next ten minutes. There was, indeed, a short and characteristic letter from Lady MacGregor, but it was only to say that she had finished and named the new game of Patience for Victoria Ray, and that, after all, she enclosed him a telegram, forwarded from Algiers to Touggourt. "I know Nevill told me that everything could wait till you got back," she explained, "but as I am sending the twins, they might as well take this. It may be of importance; and I'm afraid by the time you get it, the news will be several days old already."

He guessed, before he looked, whence the telegram came; and he dreaded to make sure. For an instant, he was tempted to put the folded bit of paper in his pocket, unread until Touggourt, or even Biskra. "Why shouldn't I keep these few days unspoiled by thoughts of what's to come, since they're the only happy days I shall ever have?" he asked himself. But it would be weak to put off the evil moment, and he would not yield. He opened the telegram.

To-day was the 25th.

---

When he looked up, the courtyard was empty, and quiet, save for the quacking of two or three forlorn ducks. Nevill had gone inside, and the Highlanders were waiting upon him, no doubt—for Nevill liked a good deal of waiting upon. The Arabs had left the animals peacefully feeding, and had disappeared into the kitchen, or perhaps to have a last look at the vanishing escort of the marabout's sacred son.

Stephen was suddenly conscious of fatigue, and a depression as of great weariness. He envied Nevill, whose boyish laugh he heard. The girl Nevill loved had refused to marry him, but she smiled when she saw him, and sent him post-cards when he was absent. There was hope for Nevill. For him there was none; although—and it was as if a fierce hand seized and wrenched his heart—sometimes it had seemed, in the last few hours, that in Victoria Ray's smile for him there was the same lovely, mysterious light which made the eyes of Josette Soubise wonderful when she looked at Nevill. If it were not for Margot—but there was no use thinking of that. He could not ask Margot to set him free, after all that had passed, and even if he should ask, she would refuse. Shuddering disgustfully, the thought of a new family scandal shot through his mind: a breach-of-promise case begun by Margot against him, if he tried to escape. It was the sort of thing she would do, he could not help recognizing. Another cause cÉlÈbre, more vulgar than the fight for his brother's title! How Victoria would turn in shocked revulsion from the hero of such a coarse tragi-comedy. But he would never be that hero. He would keep his word and stick to Margot. When he should come to the desert telegraph station between Toudja and Touggourt, he would wire to the Carlton, where she thought of returning, and explain as well as he could that, not expecting her quite yet, he had stayed on in Africa, but would see her as soon as possible.

"Better hurry up and get ready for dinner!" shouted Nevill, through a crack of their bedroom door. "I warn you, I'm starving!"

By this time the Highlanders were out in the courtyard again—two gigantic figures, grotesque and even fearful in the eyes of Arabs; but there were no Arabs to stare at them now. All had gone about their business in one direction or other.

Stephen said nothing to his friend about the enclosure in Lady MacGregor's letter, mentioning merely the new game of cards named in honour of Miss Ray, at which they both laughed. And it seemed rather odd to Stephen just then, to hear himself laugh.

The quick-falling twilight had now given sudden coolness and peace to the desert. The flies had ceased their persecutions. The whole air was blue as the light seen through a pale star-sapphire, for the western sky was veiled with a film of cloud floating up out of the sunset like the smoke of its fire, and there was no glow of red.

As the two friends made themselves ready for dinner, and talked of such adventures as each had just passed through, they heard the voice of the landlord, impatiently calling, "Abdallah! Abdallah!"

There was no reply, and again he roared the name of his servant, from the kitchen and from the courtyard, into which he rushed with a huge ladle in his hand; then from farther off, outside the gate, which remained wide open. Still there came no answer; and presently Stephen, looking from his bedroom, saw the Frenchman, hot and red-faced, slowly crossing the courtyard, mumbling to himself.

Nevill had not quite finished his toilet, for he had a kind of boyish vanity, and wished to show how well and smart he could look after the long, tiresome journey. But Stephen was ready, and he stepped out, closing the door behind him.

"Can't you find your servant?" he asked the keeper of the bordj.

"No," said the man, adding some epithets singularly unflattering to the absent one and his ancestors. "He has vanished as if his father, the devil, had dragged him down to hell."

"Where are the others?" inquired Stephen. "My men and my friend's men? Are they still standing outside the gates, watching the boy and his caravan?"

"I saw them nowhere," returned the Frenchman. "It is bad enough to keep one Arab in order. I do not run after others. Would that the whole nation might die like flies in a frost! I hate them. What am I to do for my dinner, and ladies in the bordj for the first time? It is just my luck. I cannot leave the kitchen, and that brute Abdallah has not laid the table! When I catch him I will wring his neck as if he were a hen."

He trotted back to the kitchen, swearing, and an instant later he was visible through the open door, drinking something out of a bottle.

Stephen went to the door of the third and last guest-room of the bordj. It was larger than the others, and had no furniture except a number of thick blue and red rugs spread one on top of the other, on the floor. This was the place where those who paid least were accommodated, eight or ten at a time if necessary; and it was expected that Hamish and Angus would have to share the room with the Arab guides of both parties.

Stephen looked in at the twins, as they scornfully inspected their quarters.

"Where are the Arabs?" he asked, as he had asked the landlord.

"We dinna ken whaur they've ta'en theirsel's," replied Angus. "All we ken is, we wull not lie in the hoose wi' 'em. Her leddyship wadna expect it, whateffer. We prefair t' sleep in th' open."

Stephen retired from the argument, and mounted a steep, rough stairway, close to the gate, which led to the flat top of the wall, and had formerly been connected by a platform with the ruined heliograph tower. The wall was perhaps two feet thick, and though the top was rough and somewhat broken, it was easy to walk upon it. Once it had been defended by a row of nails and bits of glass, but most of these were gone. It was an ancient bordj, and many years of peace had passed since it was built in the old days of raids and razzias.

Stephen looked out over the desert, through the blue veil of twilight, but could see no sign of life anywhere. Then, coming down, he mounted into each squat tower in turn, and peered out, so that he might spy in all directions, but there was nothing to spy save the shadowy dunes, more than ever like waves of the sea, in this violet light. He was not reassured, however, by the appearance of a vast peace and emptiness. Behind those billowing dunes that surged away toward the horizon, north, south, east, and west, there was hiding-place for an army.

As he came down from the last of the four towers, his friend sauntered out from his bedroom. "I hope the missing Abdallah's turned up, and dinner's ready," said Nevill gaily.

Then Stephen told him what had happened, and Nevill's cheerful face settled into gravity.

"Looks as if they'd got a tip from the marabout's men," he said slowly.

"It can be nothing else," Stephen agreed.

"I blame myself for calling the twins inside to help me," said Nevill. "If I'd left them to moon about the courtyard, they'd have seen those sneaks creeping away, and reported."

"They wouldn't have thought it strange that the Arabs stood outside, watching the boy go. You're not to blame, because you didn't see the sly look in my fellows' faces. I had the sign, and neglected it, in spite of my resolutions. But after all, if we're in for trouble, I don't know that it isn't as well those cowards have taken French leave. If they'd stayed, we'd only have had an enemy inside the gates, as well as out. And that reminds me, we must have the gates shut at once. Thank heaven we brought those French army rifles and plenty of cartridges from Algiers, when we didn't know what we might be in for. Now we do know; and all are likely to come handy. Also our revolvers."

"Thank heaven and my aunt for the twins, too," said Nevill. "They might be better servants, but I'll bet on them as fighters. And perhaps you noticed the rifles her 'leddyship' provided them with at Touggourt?"

"I saw the muzzles glitter as they rode along on camel-back," Stephen answered. "I was glad even then, but now——" He did not need to finish the sentence. "We'd better have a word with our host," he said.

To reach the dining-room, where the landlord was busy, furiously clattering dishes, they had to pass the door of the room occupied by the sisters. It was half open, and as they went by, Victoria came out.

"Please tell me things," she said. "I'm sure you're anxious. When we heard the landlord call his servant and nobody answered, Saidee was afraid there was something wrong. You know, from the first she thought that her—that Cassim didn't mean to keep his word. Have the Arabs all gone?"

Nevill was silent, to let Stephen take the responsibility. He was not sure whether or no his friend meant to try and hide their anxiety from the women. But Stephen answered frankly. "Yes, they've gone. It may be that nothing will happen, but we're going to shut the gates at once, and make every possible preparation."

"In case of an attack?"

"Yes. But we have a good place for defence here. It would be something to worry about if we were out in the open desert."

"There are five men, counting your Highlanders," said Victoria, turning to Nevill. "I think they are brave, and I know well already what you both are." Her eyes flashed to Stephen's with a beautiful look, all for him. "And Saidee and I aren't cowards. Our greatest grief is that we've brought you into this danger. It's for our sakes. If it weren't for us, you'd be safe and happy in Algiers."

Both men laughed. "We'd rather be here, thank you," said Stephen. "If you're not frightened, that's all we want. We're as safe as in a fort, and shall enjoy the adventure, if we have any."

"It's like you to say that," Victoria answered. "But there's no use pretending, is there? Cassim will bring a good many men, and Si MaÏeddine will be with them, I think. They couldn't afford to try, and fail. If they come, they'll have to—make thorough work."

"Yet, on the other hand, they wouldn't want to take too many into their secret," Stephen tried to reassure her.

"Well, we may soon know," she said. "But what I came out to say, is this. My sister has two carrier pigeons with her. One has hurt its wing and is no use. But the other is well, and—he comes from Oued Tolga. Not the ZaouÏa, but the city. We've been thinking, she and I, since the Arab servant didn't answer, that it would be a good thing to send a letter to—to Captain Sabine, telling him we expected an attack."

"It would be rather a sell if he got the message, and acted on it—and then nothing happened after all," suggested Nevill.

"I think we'll send the message," said Stephen. "It would be different if we were all men here, but——"

Victoria turned, and ran back to the open door.

"The pigeon shall go in five minutes," she called over her shoulder.

Stephen and Nevill went to the dining-room.

The landlord was there, drunk, talking to himself. He had broken a dish, and was kicking the fragments under the table. He laughed at first when the two Englishmen tried to impress upon him the gravity of the situation; at last, however, they made him understand that this was no joke, but deadly earnest. They helped him close and bar the heavy iron gates; and as they looked about for material with which to build up a barrier if necessary, they saw the sisters come to the door. Saidee had a pigeon in her hands, and opening them suddenly, she let it go. It rose, fluttered, circling in the air, and flew southward. Victoria ran up the dilapidated stairway by the gate, to see it go, but already the tiny form was muffled from sight in the blue folds of the twilight.

"In less than two hours it will be at Oued Tolga," the girl cried, coming down the steep steps.

At that instant, far away, there was the dry bark of a gun.

They looked at each other, and said nothing, but the same doubt was in the minds of all.

It might be that the message would never reach Oued Tolga.

Then another thought flashed into Stephen's brain. He asked himself whether it would be possible to climb up into the broken tower. If he could reach the top, he might be able to call for help if they should be hard-pressed; for some years before he had, more for amusement than anything else, taken a commission in a volunteer battalion and among many other things which he considered more or less useless, had learned signalling. He had not entirely forgotten the accomplishment, and it might serve him very well now, only—and he looked up critically at the jagged wall—it would be difficult to get into that upper chamber, a shell of which remained. In any case, he would not think of so extreme a measure, until he was sure that, if he gave an alarm, it would not be a false one.

"Let's have dinner," said Nevill. "If we have fighting to do, I vote we start with ammunition in our stomachs as well as in our pockets."

Saidee had gone part way up the steps, and was looking over the wall.

"I see something dark, that moves," she said. "It's far away, but I am sure. My eyes haven't been trained in the desert for nothing. It's a caravan—quite a big caravan, and it's coming this way. That's where the shot came from. If they killed the pigeon, or winged it, we're all lost. It would only be childish to hope. We must look our fate in the face. The men will be killed, and I, too. Victoria will be saved, but I think she'd rather die with the rest of us, for MaÏeddine will take her."

"It's never childish to hope, it seems to me," said Nevill. "This little fort of ours isn't to be conquered in an hour, or many hours, I assure you."

"And we have no intention of letting you be killed, or Miss Ray carried off, or of dying ourselves, at the hands of a few Arabs," Knight added. "Have confidence."

"In our star," Victoria half whispered, looking at Stephen. They both remembered, and their eyes spoke, in a language they had never used before.

In England, Margot Lorenzi was wondering why Stephen Knight had not come to meet her, and angrily making up her mind that she would find out the reason.
