In the chill grey gloom of the fields — damp, depressing, and misty — with the wreckage of the airship piled up around him, and the insensible woman lying at his feet, Dan stood bewildered, his nerves jangling like ill-tuned bells. The twenty feet fall had not harmed him in limb or body; but the violent contact with the earth, broken in some measure by the fact that his enemy’s aeroplane had been underneath, resulted in a displacement of his normal powers. He felt battered and bruised, deadly sick and wished to lie on the wet grass, indifferent to everything and everyone. But with a dangerous creature at his elbow, this was not to be thought of, even though that same creature was unable to exercise her wicked will. Moreover, The Grange was only a stone’s throw distant, and doubtless Mrs. Jarsell had been watching for the coming of her friend. If this were the case, she would come out with help — for Queen Beelzebub that is. How Halliday would be treated he was much too muddled in his brain to consider. Finally, he dropped on his knees, longing for brandy to pull him together, and began to think with difficulty.

This woman was not Mrs. Jarsell, but Miss Armour. Seeing that he knew her to be old, feeble, and paralysed, this was most remarkable. Curberry had called her Queen Beelzebub, so Miss Armour, and not Mrs. Jarsell, was the head of the Society of Flies, and the cause of all the trouble. In a weak way, Dan considered that she evidently was not so old as she had made herself out to be, and certainly she was not paralysed. No woman without the use of her limbs could have escaped so swiftly, or have worked the aeroplane so dexterously. Miss Armour, the delicate, kind-hearted old lady, was the infernal Queen Beelzebub who had spoken behind the mask when in the darkness the scarlet light had made an accursed halo round her head. And now she was dead — stone dead.

A moment’s reflection assured him that he could not be certain on this point without examination, so he tore open her dress, and laid his hand on her heart. It beat feebly, so he knew that she was still alive, although she was crumpled up in a heap amidst the wreckage. This knowledge restored Halliday more positively to his senses. She was so dangerous that, even helpless as she appeared to be, he could not tell what devilry she might not make use of to get the upper hand. She still had the piece of steel tipped with the deadly snake poison, and even a feeble woman could inflict death with that. The idea made Dan search in her pockets to secure the subtle weapon of defence, but even while he fumbled and hunted, he was pulled violently backward.

“Mr. Halliday!” gasped Mrs. Jarsell, holding a lantern to his white face; “hold him,” she added to a couple of men who were beside her.

“I’ve — I’ve caught Queen Beelzebub red-handed,” muttered Dan, striving to get on his feet, and thinking in a muddled way that Mrs. Jarsell had seen the arrival of the aeroplanes, the battle in the air, and the catastrophe. She must have come stealthily across the intervening fields with her myrmidons, and thus he had been caught unawares. He knew well that once in her grip, since she was an accomplice of Queen Beelzebub’s he could expect no mercy, and what was worse, Lillian would be in danger. He therefore in a weak way, fought his best to escape. If he could only reach Mrs. Pelgrin’s hotel he would be safe. But the men were too strong for him, and he was beaten to his knees. Then, what with the hunger that gnawed him, the bitter cold, the fall, and the general surprise of the situation, his senses left him. He uttered a weary sigh, and slipped to the ground, limp and unconscious.

Then again, as had happened when Penn had drugged him in the taxi-cab, he felt himself swallowed up in gloom; felt himself falling interminably, and lost sight of the physical world and its surroundings. To all intents and purposes he was dead, and from the moment he closed his eyes in that misty meadow he remembered nothing more.

When his eyes opened again, they shut at once, for the blaze of light was painful. Dimly he fancied that he heard a telephonic voice give an order, and he felt that some ardent spirit was being poured down his throat. The fiery liquor put new life into him; his heart began to beat more strongly, and he felt that his weak limbs were regaining a fictitious strength. With a thankful sigh he opened his eyes again, and a bewildered look round made him understand that he was in the barbaric sitting-room of The Grange. He saw the violent contrasts of red and yellow and black; he realised the glare and glitter and oppressive splendour of the many lamps, and his nostrils were filled with the well-known Sumatra scent. Reason came back to him with a rush, and he knew in what a dangerous position he was placed. Here he was in the power of Queen Beelzebub and her factotum, Mrs. Jarsell — at their mercy completely, as it were, although he was assured that he would receive none at all. He had hunted down the gang; he was breaking up the gang; and now in his hour of triumph he was at the mercy of the gang. Queen Beelzebub was top, tail, and bottom of the society, and he was in her grip. She would not relax it, he knew very well, until the life was squeezed out of him.

The realisation of his danger and the memory of what his helplessness meant to Lillian, nerved him to recover full control of his consciousness. While there was life there was hope, and as his captors had not murdered him while he was insensible, Dan concluded that they would not do so when he had recovered his wits. Queen Beelzebub would play with him, he fancied, as a cat plays with a mouse, and in that case he might find some means of escape. So far he had beaten her all along the line, and he might beat her still, although she certainly held the winning cards at the moment. As these things flashed across his brain, he yawned and stretched himself, looking round in a leisurely way as he did so. Still feeling a trifle stiff and sore, his thinking powers were nevertheless in good working order, as they at once responded to the command of his indomitable will. Therefore, with wonderful self-control, he smiled amiably, and stared into every corner, in order to spy out the weakness of the land. But he was being watched, as he soon knew, and his thoughts were read.

“No,” snarled a silvery voice, higher in tone than that of Mrs. Jarsell, “I have you and I mean to keep you.”

Queen Beelzebub, alive and well, and as completely in possession of her senses as he was, sat in her big carved chair near the open fireplace just as she had sat when he paid that long distant visit with Freddy Laurance and Mildred. Her face was as wrinkled as ever, but instead of being of the ivory hue which had impressed him on a former occasion, it was deadly white, and looked particularly venomous. Her white hair had been smoothly brushed and she wore a loose cloak of scarlet velvet, which fell to her feet. But in the fall she had suffered, since Dan noticed that her right arm was bound up in bandages and splints, resting in a black silk scarf against her breast. His eyes fastened on this, and Miss Armour laughed in a thin, spiteful manner, which hinted at the wrath that consumed her.

“Yes,” she said, in answer to his mute query, “I have broken my arm, thanks to you, Mr. Halliday. You smashed my aeroplane and sent me to the ground.”

“That is what you tried to do with me,” said Dan, drily, and settling himself comfortably in his chair, since he felt convinced that he was in no immediate danger. “Tit for tat, Queen Beelzebub, or shall I call you Miss Armour?”

“The real name or the feigned name, doesn’t matter,” rejoined the lady, very coolly, “you can call me what you like for the time you have to live.”

“Oh!” said Halliday, equally coolly, and aware that the cat-and-mouse torment was beginning, “so that’s it, is it?”

Mrs. Jarsell stood beside her friend’s chair, and was handing her food in an anxious manner. The large and ponderous woman looked like a child overcome with terror. Her eyes were sunken, her cheeks were hollow, and the immense vitality she possessed appeared to be at a very low ebb. She was arrayed in white as usual, but her garb was not so colourless as her face. She even looked smaller than formerly, and was shrunken in her clothes. There was something pitiful in the spectacle of this large phlegmatic female broken down, worn out, and overcome with dread of the future. As she attended to Miss Armour the tears rolled down her face, which had so suddenly grown old. The sight seemed to irritate the other woman, who was much more frail, but who had a much more powerful will. Dan saw in a flash that he had been mistaken in thinking that Mrs. Jarsell was strong. Her strength lay in her imposing looks; but she was the mere tool of that fragile, delicate old lady, whose glittering eyes revealed the iron will, which dominated her weak age-worn body. Here, indeed, was the true Queen Beelzebub, driven into a corner and prepared to fight to the last. Halliday felt, with a creeping of the flesh, that he had come to grips with an evil power, which it would be desperately hard to conquer. Miss Armour saw the shadow in his eyes.

“You’re afraid,” she taunted him.

Dan agreed. “Not physically, you understand,” he said quietly, “but you seem to be so thoroughly wicked that the spiritual part of myself quails for the moment. But it doesn’t matter much, you know, seeing that you have much more cause to fear that I may shoot you at sight,” and he fumbled in his pocket for Curberry’s revolver which he had picked up when leaving the room.

“I removed that when you were insensible,” gasped Mrs. Jarsell, wiping her eyes and turning a heavy white face in his direction.

“Of course,” said Miss Armour, in a hard voice. “I ordered the search to be made in case you had any weapons. Now you are quite defenceless, and at my mercy, you meddling ape.”

“How long have I been insensible?” asked Dan, ignoring the feminine spite which led her to call him names.

“For quite an hour!” sighed Mrs. Jarsell, whose great body was shaking, as if with the ague. “I had you brought here along with Miss Armour. You were both in a kind of faint. Now you are all right, and —”

“And I am all right,” finished Miss Armour, imperiously, “which is much more to the purpose. Better had you died when you fell from the aeroplane, Mr. Halliday, than have recovered so completely as you seem to have done.”

“You mean mischief?”

“Oh, yes, I mean mischief,” replied Queen Beelzebub, amiably, “and I mean torture, such as will make you wince. I’ll prove what sort of a man you are.”

“You had better make haste then,” said Dan, with a shrug, and bracing up his courage to beat this fiend with her own weapons, “by this time the police know all about Curberry.”

“What’s that to me? The police can’t connect me with his death?”

“Not so far as you know, but as my friend Laurance promised to take action at five o’clock if he did not hear from me, I expect with the Blackheath and Hampstead inspectors he is now in Lord Curberry’s house. An explanation from Laurance will soon bring the authorities to this den.”

Mrs. Jarsell burst into hysterical tears. “I knew there was great danger,” she wailed. “I knew that the end had come!” and she sank at Miss Armour’s feet in a fit of despair, the picture of a beaten woman.

“Oh, shut up, Eliza!” said Queen Beelzebub savagely, and her eyes glittered more venomously than ever, “you always play the fool when wits are needed to keep things straight.”

“You can’t keep them straight,” said Dan, calmly, lounging in his chair, “your career is at an end, Miss Armour.”

“We’ll see about that, Mr. Halliday. Oh, you needn’t look at me in that way, my friend! I still have the snake-poisoned lancet, you know, and if you try to spring on me, even though my arm is broken, you will meet with a sudden and unpleasant death.”

“I don’t want to touch you,” retorted Halliday. “I shall leave the hangman to finish you off.”

“That he never shall do,” snapped Miss Armour, her eyes flashing and her nostrils dilating, “not one member of that glorious society I have founded shall ever be done to death by those accursed people in authority. I, and my subjects who obey me so loyally, will vanish.”

“Will you? Not while the ports and railway stations are watched,” sneered Halliday, with contempt, “and I don’t think your friend Vincent can supply aeroplanes in sufficient quantity for you all to get away. Even if you did by some extraordinary chance, the world would be hunted for you.”

“It can be hunted from the North Pole to the South, Mr. Halliday, but neither the members of the Society of Flies nor its queen will be discovered. We will be as if we had never been,” she concluded triumphantly, and as she spoke, the big woman, sobbing at her feet, shivered and shook, and uttered a muffled cry of terror.

Queen Beelzebub kicked her. “Get up, Eliza, you fool!” she said, contemptuously, “you know quite well that I have made ready for everything this long time.”

“But I don’t want to —”

“If you say another word,” interrupted Miss Armour, viciously, “you shall afford sport for the society, as this meddling beast shall do.”

Dan laughed gaily, determined not to show the white feather, although his heart was filled with fear. He did not mind a clean, short, sharp death, but he did not wish to be tortured and mutilated, as he believed this incarnate demon intended he should be. Curiously enough, his laugh instead of exciting Queen Beelzebub to further wrath seemed to extort her unwilling admiration.

“You are a brave man, Mr. Halliday,” she muttered, reluctantly; then burst out furiously, “Oh, you young fool, why did you not accept the offer I made you?”

“The offer you prophesied in this very room would be made,” said Halliday, complacently; “well, you see, Miss Armour, or Queen Beelzebub, or whatever you like to call yourself, I happen to have a conscience.”

“That is your weakness,” said the woman, calmly, “throw it on the rubbish heap, my friend. It is useless.”

“Now it is, so far as joi............
