“ Benstein smiled. "I shall like her, but I shall like Miss Lyne a great deal better. And if you try to force her to marry that detestable little Arnott I shall do my best to spoil your hand."
Frobisher's teeth flashed in one of his uneasy grins. He felt like a man who has discovered a new volcano quite unexpectedly. What an amazing lot this woman knew, to be sure; what an extraordinary fascination she must exercise over her doting husband. He followed her glance now to a distant seat under a tree where Angela and Harold Denvers were talking together. ”

“ To Frobisher's pêtit dîner the same evening of that eventful day ostensibly to meet the Shan of Koordstan, Lefroy came large and flamboyant, with a vivid riband across his dazzling expanse of shirt and a jewelled collar under his tie. There was an extra gloss on his black moustache, his swagger was a little more pronounced than usual. He looked like what he was—a strong man weighed down by not too many scruples. ”

“ CHECK TO FROBISHER.
The whole thing struck Angela as strangely unreal. It hardly seemed possible that this swiftly-moving drama could be played amongst the settings of her daily life in this fashion. There was the dreamy music of the band—the Scarlet Bavarian Band of so many big social functions—the familiar fuss and flutter of drapery, the sound of well-known voices. Mrs. Benstein was smiling in the most natural way, the two men appeared to be quite at their ease. And yet here was a moving drama that any one moment might flare into tragedy. Still, Angela played the game mechanically. ”

“ Frobisher said, still laughing in the same noiseless way. "Surely you're not so accomplished a liar that you haven't learned to know the truth when you see it. I pay Mrs. Benstein the compliment of believing every word that she says. We have exposed our hands for nothing, and been outwitted by a very clever woman. You'll gain nothing by losing your temper."
"Who could she have passed the jewel on to?" Lefroy growled.
"Ah, that is the point! Knowing nobody here and all! Madame, I kiss your hand. You have made Clement Frobisher look and feel like a fool. ”

“ Yet the diamonds did not seem in the least out of place on Mrs. Benstein. There was something hard and shaky about her beauty that called for them—blue black hair drawn back in a wave from her forehead, a complexion like old ivory, and eyes suggestive of mystery. Frobisher thought of the serpent of old Nile as he looked at her critically.
A marvellously beautiful woman beyond all question, a woman without the faintest suggestion of self-consciousness. ”

“ Up in the roof, out of a faint cloud of steam, other blossoms of purple and azure peeped.
Complimented upon the amazing beauty of his orchid-house, Sir Clement Frobisher cynically remarked that the folly had cost him from first to last over a hundred thousand pounds. He passed for a man with no single generous impulse or feeling of emotion; a love of flowers was the only weakness that Providence had vouchsafed to him, and he held it cheap at the money. ”

“ Angela led the way. It was fairly light in the great glass tank with its tangle of blooms, but as Denvers entered a great gush of steam shot up from the automatic pipe and filled the dome with vapour. Harold quickly drew the long steps to the centre and mounted. He disappeared in the mist and was quickly lost amongst the tangle of ropes and blossoms. He had to wait for the periodical cloud of vapour to pass away before he could make a searching examination. So far as Angela could see, nobody was in the roof at all, it was as if Denvers had disappeared, leaving no trace behind. ”

“ Mrs. Benstein cried in affected surprise. "Here is one for Mr. Parkford, and there is one for Mr. Denvers. Positively, I see nothing of the shade to suit the colouring of His Highness the Shan. Ah, here is the very thing! Excuse me, Miss Lyne."
The speaker bent down and broke off a little spray of one blossom of the purple orchid from Angela's belt, and herself fixed it in the lapel of the Shan's immaculate coat.
"Who can say that it is not in perfect taste?" she cried. "It is the very shade. We will sit down, and unless Sir Clement Frobisher turns up in time we will proceed without him." ”

“ Denvers returned to the ballroom with a feeling that he would be glad to get away. The whole thing sickened him, the light laughter and frivolous chatter jarred upon his nerves. He had been very near to a dreadful tragedy; he had learnt a hideous truth, and he had not got himself in hand yet. He wanted to know the whole truth without delay. Angela awaited him anxiously.
"My aunt tells me that Mrs. Benstein is gone," she said. "She had an accident with her dress. Harold, you look as if you had seen a ghost."
"I have seen the devil, which is much the same thing," Harold murmured. ”

“ As the moisture struck the very coarse Manilla rope it suddenly tightened with the moisture till it hummed again. The same effect was to be seen with a clothes-line after a shower of rain. But the almost diaphanous character of the rope and the heavy discharge of moisture brought the strands up so tight that they seemed to hum in the air.
"There!" Harold cried, "there is the mystery—there is the secret of the priests. The man climbs until he is in a maze of loose rope; the steam is discharged and he is strangled—the life pressed out of him by those cruel cords; one cry and all is over. ”

“ The voice trailed off with a muttered suggestion of wickedness beyond words. Frobisher lay back in his chair with the tangled ropes of blossoms about his sleek head; a great purple orchid with a living orange eye broke from the cluster and hung as if listening. Lopez looked round the bewildering beauty of it all with an artistic respect for his surroundings.
"The devil has looked after his dear friend carefully," he said, with the same calm contempt. Frobisher indicated it all with a comprehensive hand. "Now you are jealous," he said. "Hafid, the other servants are gone to bed? Good! ”

“ Angela coloured slightly; after all, her attentions were not quite disinterested.
"Perhaps it is because you fascinate me," Angela said frankly. "I have never seen any one like you before. I love character. And yet, you seem quite lonely, as if you were apart from the rest."
"Well, so I am," Isa Benstein replied. "The men on occasions like this count for nothing. I never see a lot of men crowded round a pretty woman without a strong temptation to laugh. They look so foolish. ”

“ It seemed almost impossible to identify intrigue and danger with so fair a scene.
The two wandered on together past the dancers and the couples sitting out, talking quietly together as if they had been no more than casual acquaintances. Harold was a dull-dogged Asiatic again, but he kept his eyes about him. The crowd grew less; it was more quiet in the region of the card-rooms. Several parties were deep in bridge here, the Shan of Koordstan amongst the number. There was a pile of gold before him; from the satisfied glitter in his eyes he was winning heavily. Harold gave a sigh of relief. ”

“ Frobisher croaked as he stooped and touched one of the shining taps near the floor. "My word, what a picture for an artist you make!"
He crept away gently, leaving his guest amidst the nodding blooms. They were so fascinating that Mrs. Benstein could think of nothing else for the moment. She had quite forgotten the events of the evening. She turned her lips to a cluster of the glorious blooms.
"They are like beautiful, fascinating snakes," she said to herself. "No wonder the man dares run the risk of having this bewildering beauty in his house. Like lovely snakes, the hiss and all complete." ”

“ As a dry air came in the long strands of the Manilla rope stretched as the moisture warmed out of it, a climber of the Moth dangled over the head of an inspector who pushed it aside, as if it had been poison. Harold produced something that looked like an oblong sack filled with firewood. He proceeded to tangle it in the loops and folds of the rope.
"We will suppose that is a man," he said, "a man who has climbed up to the roof to steal the Moth which is all tangled up. He puts his arm through one loop and his head through another, thinking no evil, when suddenly the steam-hose is turned on. ”

“ Beyond it was a dull baize door, and beyond that an inner hall magnificently furnished. A gorgeous footman took Lopez's hat and coat, and he proceeded to make his way up the marble staircase. There were more baize doors, and as Lopez paused, the murmur of voices grew louder. Lopez came at length to a magnificent double drawing-room, where the electric lights were low and dim under crimson shades, and where a score or two of men were gambling. There was a roulette-table, which was well patronised, with tables for other games. ”

“ And I'll swear that Miss Lyne was not in the secret."
"She was not; her face would have betrayed her. Now you can imagine the pleasure with which I watched Sir Clement and Hamid Khan across the luncheon-table. And you call Frobisher a clever man!"
"He is by far and away the cleverest man I ever met, Madame."
"He is nothing of the kind," Mrs. Benstein said contemptuously. "For depth and cunning he has no equal, I admit. But intellect he has little, and imagination none at all. The fellow generally scores because his plots, as a rule, are laid against honest people. ”

“ Manfred," he yelled. "Lying on the floor in the conservatory, dead. Take it and burn it, and destroy it. Take it and burn it, and destroy it. Take it——"
Frobisher pounced upon the wailing speaker and clutched him by the throat. As the first hoarse words came from Hafid the rest of the party had rushed headlong into the orchid-house. Frobisher shook his servant like a reed is shaken by a storm.
"Silence, you fool!" he whispered. "You didn't kill the man, and I didn't kill the man. If he is dead he has not been murdered. ”

“ He felt pretty sure that my husband would let me have the Blue Stone to wear. I am in danger."
"I don't think you are exactly in danger," Angela said.
"Oh, yes, I am. You don't know everything, I can see. The Shan of Koordstan is here to-night."
"He is here with one of his suite called Aben Abdullah, who, by the way, is my beloved one in disguise. He is Harold Denvers, who is aiding the Shan."
"A romance, a veritable romance, with danger and difficulties clinging to it like an aroma. So I am to play the part of one of Sir Clement's puppets! We shall see. Now tell me everything." ”

“ 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?" ”

“ He grew a little tired of his own company presently and strolled into the ballroom. There the electrics were festooned and garlanded with ropes of roses, the plaintive band could not be seen behind a jungle of feathery ferns, a bewildering kaleidoscope of colour looped and twisted and threaded in a perfect harmony.
A few of the younger and consequently more blasé men lined the walls. A cavalier of sorts with a long, thin scar on the side of his lean head was watching the proceedings. Frobisher touched him on the arm.
"Not dancing, Lefroy?" he said. "Are you past all those fleeting joys?" ”

“ Money seems to be everything. Your poor aristocrat sneers at the monied people. But ain't they just as ostentatious themselves! Don't they rob their creditors and neglect their bills to appear like other people? It seems such a dreadfully snobbish thing to do."
The fine eyes were looking round contemptuously, the breastplate of rubies heaved slowly. The words sounded strange from one so superbly attired, and Mrs. Benstein laughed as she caught Angela's smile. ”

“ I'll show you an orchid when you have time to examine it that will move even you to admiration. But not now; she is too superb a creature for passing admiration. Now I think you will do."
There was no question of Frobisher's taste or his feeling for arranging flowers. The blossoms looked superb and yet so natural as they lay on Angela's breast—white orchids shot with sulphur. They were the theme of admiration an hour later at Lady Marchgrave's charity concert; they gleamed again on Angela's corsage as she sat in the Grosvenor Square drawing-room at dinner. ”

“ It was on the tip of Lefroy's tongue to snarlingly reply that Frobisher knew perfectly well, but that was bad policy under the circumstances.
"You are typical of the spirit of the age," he said. "All the same, I hardly expected to see the wife of a moneylender under your roof. Lady Frobisher——"
"Has progressed rapidly of late in the cult of the proletariat. So Mrs. Benstein is the lady of the rubies. I half expected it from the first—only the wife of a moneylender could sport jewels like that. But she is a beautiful woman, Lefroy, and she is going to make a great social success." ”

“ 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. ”

“ Benstein deceived—by some magnetic process Lady Frobisher had been forced to be polite, and ask her to that fancy-dress ball. Mrs. Benstein had smiled, but she had seen the rooted repugnance in Lady Frobisher's face, the constrained look in her eyes.
"I wonder how he managed it?" she asked herself as she drove along. "And what does that little creature with the brow of a Memnon and the mouth of a tom-cat want to get out of me? Money is at the root of most things, but it can't be money in that quarter." ”

“ 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. ”

“ You have valuable orchids, Sir Clement?"
Frobisher nodded. He was not quite so cool now, and an irritating lump was working at the back of his throat. His quick mind began to see what was behind these apparently innocent questions.
"I have probably the finest collection in England," he replied.
"Many of them would tempt a thief, I suppose?"
"Well, I dare say. There are orchid collectors all over the world, you see. Once a man gets hold of that passion it seldom leaves him. A valuable stolen orchid would be a marketable commodity." ”
