Part 10

"These flowers are in it," she said. "The Cardinal Moth must play its part with the rest. There will be no rest until the Moth is back again over the altar in the temple of Ghan. You wonder perhaps how I know all these things, but the blood of all nations contrives to make the mystery that is called Isa Benstein. Now I want you to bring General Pearson to me; I want you to stay here whilst we go away for a dance together. Sir Clement, and perhaps another man, will be looking for me. Say that I shall be back here in ten minutes to see you. You need say no more than that."

Angela went away, wondering but obedient. The handsome old soldier would be delighted. He had been looking for his next partner for a long time. He was quite distracted by her absence. They walked away together, leaving Angela behind. Presently in the distance she could see the figure of Frobisher wandering in and out of the crowd. Angela walked smiling up to him.

"Hide-and-seek," she cried gaily. "You are looking for somebody?"

"Even the Queen of the Rubies," Frobisher responded in a similar strain. "A handsome reward will be paid to anybody giving information as to her present whereabouts."

"You may keep your beloved money," Angela said. "I am above such things. Mrs. Benstein is dancing with General Pearson, and in ten minutes she has asked me to meet her under the lamps yonder. And here comes Count Lefroy, as if he were looking for somebody, too."

Angela slipped away as Lefroy came up, showing his teeth in a queer, uneasy smile. He was trembling, too, as if he had run a long distance. Frobisher suppressed a disposition to snarl.

"You have finished, then?" he asked. "My rubies were worthy of a closer inspection."

"And would have had the closer inspection only Lady Frobisher was called away," Lefroy replied. "Her ladyship would have left me alone with them but I implored her not to place so fierce a temptation in my way. She does not know that I share your passion for those stones, especially large ones."

"Like the Blue Stone of Ghan, for instance?" said Frobisher, with a sharp indrawing of his breath. "It would be good to get hold of that, eh?"

Lefroy's eyes grew a trifle harder and more uneasy. He seemed to be miserably uncertain in his mind, divided in opinion as to whether he should stay where he was or go away on some errand of his own. The crowd became slightly more thick as the strains of music ceased and the dance came to an end. In spite of everything, the rooms were growing unpleasantly warm, and the guests were seeking cool corners. Mrs. Benstein came presently, leaning on the arm of her military escort. Her face was turned away, so that neither of the two men watching her could see her features.

Lefroy drew a deep, long breath. The time had come, he would have to stand up and fight Frobisher, the secret that he had half deemed his own was on the verge of exposure.

"Mrs. Benstein is going into the conservatory," he said meaningly. "I propose to follow her wise example and do the same thing. A sybarite like you does not care for robust air. I presume, therefore, that you are going to stay where you are."

Frobisher hooked his arm quite affectionately through that of his companion.

"On the contrary, I feel that a tonic would do me good," he said sweetly. "I am distressed for your sake. There is a nervousness about you to-night that alarms me; I could not enjoy myself thinking about it. What should I do, where should I be without my Lefroy? Orestes and Pylades, Damon and Pythias _et hoc_, where are you all alongside of Lefroy and Frobisher?"

He led the way into the conservatory close to where Mrs. Benstein and her companion were seated. By accident or design, Isa Benstein had her back to them. She seemed to be chatting gaily and without a trouble in the world to the General, who rose presently and proceeded back in the direction of the ballroom on ices bent. Then Mrs. Benstein rose and sauntered to the door of the conservatory. Both the men there watched her breathlessly--the time had come, and they both of them knew it.

She wheeled round suddenly as if conscious of their presence and smiled gloriously.

"I am admiring the flowers," she said. "They are exquisite. But I must have a word with Miss Lyne, whom I see in the distance. If my distracted General misses me, pray tell him that I shall be back at once. I trust you to do this for me, Sir Clement?"

Frobisher nodded with his mouth wide open, even he felt at a loss for words. There stood the lady of the rubies, her dress glistening with the gems, but her fair broad brow was clear as day, there was no vestige of a stone to mar its pure symmetry.

"It's a wonderfully warm night," Frobisher gasped.

"Sultry," Lefroy said meaningly, "very sultry. Deprives you of your wits, doesn't it? Weren't you saying something just now about the Blue Stone of Ghan? Or did I dream it? Come along."

"Where to?" Frobisher asked, like a man in a dream.

"Why, to the smoking-room, to be sure," Lefroy said with polite mockery. "As you told me just now with such tender consideration for others, you are not quite yourself. A little brandy, the brandy you know, and a small soda. You seem to want it badly."

"Egad," Frobisher burst out bitterly; "egad, I fancy we both do!"

*CHAPTER XVIII.*

*A DEFENSIVE ALLIANCE.*

Lefroy's face, on the whole, was the more composed of the two. It was not often, in public at any rate, that Frobisher allowed his passion to get the better of him, but for the moment he was utterly taken aback. He had planned his scheme so neatly, the whole cunning skein had reeled off so splendidly that the startling disappointment was all the more maddening.

"Nothing like the old brandy," Lefroy sneered. "You will find it a sovereign cure."

But Frobisher was recovering himself slowly. He was not the man to show his hand for long. The dry, hard smile was on his face now, the passionate desire to hurt something had passed away. Ignoring Lefroy's remark, he passed on in the direction of Mrs. Benstein.

"I have been looking for you everywhere," he said. "One does not usually have to hunt for the sun, but in this case the planet would seem to be a retiring one. Does my house afford such poor attraction that you should bore yourself in this lovely spot?"

"I am not in the least bored," Mrs. Benstein said, with one of her most brilliant smiles. "On the contrary, I have been enjoying myself immensely. I am merely resting."

Frobisher said something appropriate. Nobody could do that kind of thing better when the mood was upon him. At the same time, his deep-set eyes were looking for signs, that might be conspired into something useful. Lefroy contented himself by standing behind and smiling vaguely.

"Your gems are all I expected them to be," Frobisher went on. "I felt certain that rubies would suit you to perfection. But you want something, a certain finish. A star or cluster on the forehead to finish. Don't you agree with me, Count?"

He flashed a wicked grin at Lefroy, who said nothing. Isa Benstein gave no sign. She smiled as she arranged the flowers, the Crimson Moth that seemed to fascinate Lefroy.

"I thought so at first," she said. "In fact, I was wearing something of the kind when I came here. But on mature consideration I decided that it looked too overpowering. Several of your splendid mirrors confirmed that impression; consequently, I removed it."

"It is in a safe place, I trust?" Lefroy said carelessly.

"Really, I suppose so. Not that it matters, seeing that it is of no particular value. It was the only sham thing that I had about me. It is with my fan somewhere."

Lefroy urged the point no further. It was not policy to say too much. The two men went off together presently, as Isa Benstein was claimed for another dance.

"The man who finds that fan will be lucky," the Count said meaningly.

"The man who finds that fan will find nothing else," Frobisher replied. "How on earth it has happened I don't know, but that woman has discovered everything. Did you see her face as we were leaving? I did. She came here in blissful ignorance of the little comedy or tragedy, or whatever you like to call it; but she has had a warning from somebody since supper. Lord bless you, she knows all about it. We couldn't ask any prying questions without arousing her suspicions, though I am of opinion that she is quite aware of the way that she has baffled us. Oh, she is a clever woman."

"Clever as they make them. But she is only a woman, after all, my friend, and liable to make mistakes like the rest of her sex. She has got that stone about her."

Frobisher's eyes gleamed. He had been thinking much the same thing. Followed by Lefroy, he repaired to the smoking-room and proffered his hospitality. For some time the Count smoked and drank in silence, waiting for a lead from his host. There was bound to be some kind of explanation between them, and Lefroy preferred the lead to come from the other.

"Silence is golden," Frobisher said, with one of his sudden grins.

"In this case," the other said. "Perhaps you would like to deal the first hand. I shall sit tight for the present."

"I fancy it is my play," Frobisher said thoughtfully. "Fate and the other players push us a long way off our line of policy sometimes. For instance, I never imagined that I should be dragged into an offensive and defensive alliance with you. But for the present it is absolutely necessary. We must get that precious gew-gew----"

"Call it the sacred Blue Stone of Ghan and have done with it," Lefroy growled.

"Very well, though it is hardly diplomacy. Mrs. Benstein came here wearing the Blue Stone. You found it out quite by accident, and it was your game to prevent me from knowing. You tried very hard, but you were a little too much taken by surprise, especially when the Shan was announced."

"That was a very awkward moment for me," Lefroy admitted.

"It was. Directly you came in here I guessed exactly what had happened. As a matter of fact, I had not the least intention of your coming here to-night, indeed I didn't know you were coming. As a matter of fact, also, my wife cordially dislikes you, and I suppose she only asked you out of compliment to me."

"We'll let that pass," Lefroy said. "I was startled when Mrs. Benstein dropped her mask and the Blue Stone stood revealed. Of course, I knew that the stone was pledged to Benstein, and that Mrs. Benstein having it was natural enough. The doting old fool had been wheedled out of it for the evening. But I didn't know that you knew that, and I was most anxious to keep the information from you. But directly I came face to face with you here, I knew that you had some deep scheme, and that you guessed that I had got wind of it. I have worked that out."

Frobisher smoked and sipped his brandy with infinite relish.

"I always like to study a subtle mind, Count," he said. "Will you explain your meaning?"

"Certainly, especially as I shall lose nothing by so doing. Why did you get your wife to ask that woman here at all? I knew you had to use something like force to bring it about. You did it because you knew where the Blue Stone was. You advised Mrs. Benstein as to her dress, you gave her hints on that head. You were quite aware of the extent of Benstein's senile devotion to his wife. And you calculated that if she adopted the ruby suggestion she would borrow the Blue Stone."

"Excellent," Frobisher said cordially. "A capital piece of reasoning. And a very pretty scheme, though I say it myself. It came off, and only your presence prevented my coup. Pray go on."

"There isn't much more to say. Once Mrs. Benstein was here wearing the Blue Stone, you had no intention of her leaving with the gem in her possession. I don't mean to say that you would have used brutal force to get it, but I do mean to say that you would not have hesitated at that if needs must. Once you had the stone you would have forced those concessions from the Shan."

"And exposed the forged ones that you deposited with Benstein," Frobisher said sweetly.

Lefroy winced, and the glass chattered against his teeth. He had not expected that stroke, and his dark face indicated the fact for a brief moment.

"That is certainly one to you," he said. "Only that is not the point for the present. The point is, that your plot has failed, that the woman who came here to-day wearing the Blue Stone out of pure vanity and with no kind of _arriere pensee_ whatever, has been warned of her danger, which she has promptly removed. She knows pretty well everything--the way she received us showed that. She is an exceedingly clever woman, and has a shrewd idea how to take care of herself. Has she got the stone still?"

Frobisher nodded gravely. Lefroy's point was worthy of consideration.

"You mean, has she passed it on to somebody else?" he said. "She might have done that, but I don't fancy so, and I'll tell you why. She has seen enough of the world to teach her not to trust anybody. Naturally enough, she does not want her husband to be ruined, as would be the case unless the stone was restored to Benstein's safe keeping without delay, and so she would trust to her own shrewdness to get away without robbery. On the whole, she has not parted with the stone."

A little reflection assured Lefroy of the soundness of this reasoning. The thing resolved itself into a game of hide-and-seek with a fortune at the end of it with any luck. Up to a certain point these men were compelled to act together, but the alliance might end at any time.

"I can't very well abduct Mrs. Benstein till she parts with the gem," he said.

"No, we can't do it, but we might find somebody who could," Frobisher smiled. "There's the Shan's minister and treacherous servant, Hamid Khan, for instance. He has scant respect for the laws of this or any other country, and he knows quite well that his master has parted with the stone. If we could put our hands upon the amiable Hamid at this moment----"

"Nothing is easier. Hamid is watching in Piccadilly at this very moment."

"So you have got a little scheme afoot, too," Frobisher laughed. "Upon my word I need all my wits to enable me to get the better of you, Count. How long has this been going on?"

"Ever since the stone left the Shan's possession. Ever since then he has been dogged and watched. Let me go and call Hamid in to our discussion. He knows what has happened, for I scribbled a few lines on a sheet of paper just now when I left your wife, and handed it to one of the smaller spies who are loafing outside. The night is hot, and our absence will not be noticed. Now slip on our coats and assume to be going to smoke a cigar in the garden. From thence we reach Piccadilly by the back way, and surprise Hamid in his dreary vigil. Then he comes back with us here. What do you say?"

Frobisher nodded gleefully; it was an intrigue after his own heart. They passed into the cool air of the garden, and from thence into the narrow lane at the back of the house. It was very late now, and Piccadilly was growing quiet, so that the few lounging figures there were easily seen. A slender, brown-faced man in a dust coat and evening dress came along smoking a cigarette. He did not appear to be in the least interested in anything only for his restless eyes.

"I want you," Lefroy said. "There's work to be done, Hamid."

"Indeed, I am glad to hear that," said the other in a remarkably English tone of voice. "I'm getting sick to death of this eternal loafing. But Sir Clement Frobisher and Count Lefroy together! My dear Count, what are you doing in that galley?"

"Any galley is good enough when your own has been temporarily wrecked," Lefroy growled. "But ask no questions for the present and come with us."

They went back again presently in the smoking-room without having attracted the least attention, or so at least Sir Clement Frobisher flattered himself. It would never do for the Shan to know of Hamid Khan's presence in the house. But there were other watchful eyes besides those of the Shan of Koordstan. Mrs. Benstein had seen the two men go into the garden, and she had seen three return. She was not quite quick enough to get sight of the third, but she had a pretty shrewd idea who he was. She waited till she could have a word with Angela.

"I want you to do something for me, at once," she said. "Sir Clement Frobisher and Count Lefroy are in the private smoking-room with a third person. I want you to open the door and rush in with Sir Clement's name upon your lips as if you are in a hurry for something. Then you can stammer an apology and close the door behind you. The great thing is to get a quick mental photograph of the third person."

Angela nodded, she wasted no time in idle questions. In the most natural fashion she burst open the door and fluttered into the smoking-room, calling upon Frobisher as she did so. Then she stammered an apology and gently closed the door again. The third person had been seated directly opposite to her so that she had a perfect view of his face.

"I see you were perfectly successful," Mrs. Benstein said.

"Oh, absolutely," Angela replied. "It is a slender man with a deep mahogany face and curly hair, quite a handsome Asiatic, in fact; but what struck me more were his eyes, which are a clear light blue. Fancy, blue eyes in a face like that!"

"Capital," Mrs. Benstein murmured. "It is exactly as I expected. No, I am not going to say any more for the present, because I don't want to spoil your enjoyment. Now go off and flirt with that handsome young fraud, called Aben Abdullah, when you have the chance. Only don't go where I shall have to hunt for you in case of dire necessity."

*CHAPTER XIX.*

*WHAT DID SHE MEAN?*

Harold was on the look out for Angela, so that she had not much trouble in finding him. His stolid Asiatic indifference was admirably feigned, and showed nothing of the anxiety within. There was just an interrogative gleam in his eyes for the moment.

"Isn't there somewhere where we can be really quiet for a few minutes?" he said. "I have successfully disposed of my royal rascal for the time, and I want badly to speak to you. Unless I am greatly mistaken, you can give me a good deal of information, Angela."

Angela's smile indicated that she could. There was a small passage behind some heavy curtains leading to a suite of rarely-used rooms, and Angela led the way there. She put the light up for a few moments and disclosed a cosy corner lounge, then she snapped off the switch again.

"I've pulled the curtain back so that it is possible to see without being seen," she explained. "We must not stay long, Harold--I am sure that Mrs. Benstein will want me before long."

Harold slipped his arm round the girl's waist, and kissed her. Stolen moments like this were very sweet. There was just an interval of blissful silence.

"Now tell me what you know," Harold asked presently, "about the Blue Stone."

"I know nothing about the Blue Stone," Angela explained. "Mrs. Benstein has done something with it. All the mischief arose from the fact that she had no idea of the traditional value of the gem. She had not asked her husband about it. As a matter of fact a cunning idea of Sir Clement's----"

"I know all about that," Harold interrupted. "It was very cunning, and came near success, only I nicked in, and you and I spoilt it between us. Lefroy spotted the stone first and tried to keep the knowledge from Frobisher, which was practically impossible. Then luck conspired to force those fellows to make an offensive and defensive alliance. But where is the stone?"

"My dear boy, I haven't the remotest idea. All I know is that it has disappeared from Mrs. Benstein's forehead, and that she seems to be enjoying the comedy."

Harold listened uneasily. He knew perfectly well that Frobisher and Lefroy would not stick at murder even to regain possession of the Blue Stone. If the sacred gem was still in Mrs. Benstein's possession she would never be allowed to reach home with the thing intact.

"I suppose we must wait on events," he said after a pause. "For the present the Shan is not likely to interfere. I have placed him safely at a bridge-table, and there he will sit so long as there is a game, though his kingdom was toppling about his ears. Still, it keeps him sober, and that is the main thing. I suppose Mrs. Benstein did not tell you what she proposed to do?"

"I didn't ask her, Harold. She is so marvellously cool and clever that I felt quite easy in my mind. But there is another foe to fight. I quite forgot to tell you about him."

"Did Mrs. Benstein tell you, or did you find it out yourself?"

"No. It was Mrs. Benstein. She said somebody was closeted in the private smoking-room with Sir Clement and Count Lefroy. I was to pretend that I didn't know, and blunder into the room, taking care to get a good sight of the stranger before apologising. I did it very well."

Harold squeezed Angela's waist affectionately. She laid a loving hand on his.

"Perhaps you know the man," she went on. "He looks like a true Asiatic, but at the same time he has blue eyes. It struck me as such a singular thing."

"I know him perfectly well," Harold muttered. "This thing goes deeper than I expected. The man who is still plotting with these two rascals is Hamid Khan, who calls himself one of the Shan's ministers. He is perhaps the most dangerous foe my pseudo-master has. If he can only prove that the Blue Stone had been out of the Shan's possession there will be a change of dynasty in Koordstan. This is the worst piece of news I have heard to-night."

"I don't quite see why you should be so deeply interested," Angela said softly.

"My darling, there is a good deal of self at the bottom of it," Harold admitted candidly. "I shouldn't take all this trouble and run all this risk for a worthless creature like the Shan, unless I could see some benefit in it. I want to pin him down over those concessions, which will make my fortune. They will give me control over one of the richest tracts of land in Koordstan. In a year or two I shall be wealthy."

"Just as if it mattered," Angela whispered, rubbing her cheek against Harold's, "just as if it mattered, when I shall have so much. But don't forget that you have Mr. Benstein to deal with. You can't rob him of the stone which he has come by honestly in the way of business."

"Oh, I know that. And we must have the stone by ten o'clock to-morrow. But I have found a way out of that difficulty. Between ourselves, Lord Rashburn showed me the way. We have a rich Englishman who will advance the money and benefit politically and secretly at the same time. He runs no risks of losing his capital either, because he is certain to get it back from the Shan in time. When Mrs. Benstein has gone home we shall follow and settle the business out of hand. I wish she would go now."

"I should trust her," Angela said thoughtfully. "She will go in her own time and her own way; she will baffle those scoundrels yet, I am certain of it. My dear boy, do be careful. If you are found out----"

Angela paused significantly. There was a risk of the mine being fired at any moment. There was no more dangerous or cunning foe in Europe than Sir Clement Frobisher, all the more dangerous in that he had Count Lefroy for an ally. And the time before the Shan was getting perilously short.

"Wait upon events a little longer," Angela urged as she arose. "We must go back again, it is not wise to stay here any longer. Mrs. Benstein may want me."
