After the storm came the calm, and with the spring a realisation of Mr. Halliday’s hopes concerning his future. Sir John Moon no longer objected to Dan as the husband of his niece, and was indeed profoundly thankful that she had escaped becoming Lady Curberry. The story of the Society of Flies, and the wickedness of Queen Beelzebub and the blowing up of The Grange was a nine day’s wonder. The papers, for some weeks, were filled with little else, and “The Moment” almost doubled its circulation when the able pen of Mr. Frederick Laurance set forth the complete story. Halliday became quite a hero, as indeed he was, although he did not appreciate the rewards of his conduct. To be interviewed, to have his portrait, more or less unlike him, in dozens of illustrated papers, to receive offers from music-hall managers, and even proposals of marriage from various enthusiastic ladies, did not appeal to Dan. As soon as he could, he went out of London and took refuge in Sir John’s country seat so as to escape publicity.

Needless to say, Lillian was there, and Mrs. Bolstreath also. Laurance was due within seven days to be Dan’s best man at the June wedding, and with him Mildred was coming at Lillian’s special request. Once, twice, and again the owner of the house had heard the story of the late events, and also had read them more or less garbled in different newspapers. Yet he never wearied of the recital, and admired Halliday greatly for the part he had played. From objecting to Dan as a nephew-inlaw the baronet now urgently desired that he should make Lillian Mrs. Halliday. In fact, when he thought of what the young man had saved Lillian from, the uncle of the girl could not do enough for his estimable young friend. So Dan, having become famous was about to become rich, but neither fame nor wealth appealed to him so much as the undoubted fact that he was on the eve of wedding the girl he adored.

“And I think,” said Lillian, holding on to Dan as if she feared to lose him, “that you and I would be as happy in a cottage as in a palace. Money is a nuisance, I think, dear.”

“You say that because you have never experienced the want of it,” said Dan, in a sententious manner. All the same he slipped his arm round the girl’s slim waist, and kissed her for the pretty sentiment she had expressed relative to a poor but Arcadian existence.

The happy pair, not yet joined in holy matrimony, but to be made one in seven days, were seated in the delightful garden of Sir John’s house, which was situated in the pleasant county of Devon. They had strolled out after dinner, leaving Mrs. Bolstreath to chat with the baronet, who approved of the big placid woman, and enjoyed her society. Lillian and Dan, however, liked to be in one another’s company without any third person to spoil their pleasure, and on this occasion — being humoured as lovers — they were entirely alone. The garden sloped down to a yellow beach, which was the curve of a tiny bay, and under the orb of a brilliant May moon, the waters of the vast sea murmured softly almost at their feet. There was a marble bench here, with a marble statue of Cupid near at hand, perched on a pedestal, so the spot was quite that which lovers would have chosen. Dan chose it, because the screen of shrubs and trees quite shut off the nook they occupied from the many windows of the great house, and he could kiss Lillian when he wished to without any uneasy feeling that someone was looking on. It is quite unnecessary to say that he frequently availed himself of his privilege. The about-to-be bride fully approved of his ardour in this respect.

“But you really must be serious,” said Miss Moon sedately, after the last embrace given out of compliment to her love-ina-cottage sentiment. “I want to ask you a few questions.”

“Ask what you will, I can deny you nothing.”

“It’s about the Society of Flies,” hesitated the girl.

“My dear,” said Dan patiently, and coaxing a loose leaf round his cigar, “I don’t want to be disagreeable, but I am really tired of the Society of Flies.”

“Only a few questions,” said Lillian, nestling to his side, “and then we can forget all about the matter.”

“That won’t be easy for me to do,” replied Mr. Halliday, rather grimly, “I can never forget what I suffered when I was expecting to be tortured by that fiend.”

“Queen Beelzebub?”

“She could not have chosen a better name, my dear. I sometimes doubt if she was a human being at all.”

“Poor, misguided woman,” murmured Lillian, resting her head on Dan’s shoulder.

“Don’t pity her, dear. She does not deserve your pity. Now, Mrs. Jarsell — I have always been sorry for her.”

“So have I,” said the girl, promptly, “she was very good to you, dear.”

“Good is a weak way of expressing what I owe her,” retorted Halliday, “think of what she saved me from.”

“Perhaps Queen Beelzebub would not have tortured you, after all.”

Dan laughed incredulously. “I shouldn’t have cared to have trusted to her mercy. I tell you, Lillian, as I have told you before, that already the implements of torture were being made ready. They would have crowned me with a red-hot circlet of steel, and pinched my flesh with red-hot pincers, and —”

“Don’t, oh, don’t,” Lillian turned pale, “it is really too dreadful! And to think that I was with Bolly at Mrs. Pelgrin’s quite ignorant of the peril you were in. I wish I had been with you.”

“I am glad you were not. My one feeling of thankfulness was that you had escaped being hurt in any way. I didn’t mind dying so long as you were all right, my darling, although I much prefer being alive and here. Lillian, my dear, don’t cry; it’s all over weeks ago.”

“I— I— I can’t — can’t help it,” sobbed the girl, clinging to him, “it is all so dreadful. When Mr. Laurance came that day with the police and said you were at The Grange, I thought I should have died.”

“There, there,” Dan soothed her, as he would have soothed a fretful child, “it is all over and done with. By the way, how was Freddy so certain that I was at The Grange? He never quite explained his certainty.”

“Well, dear,” said Miss Moon, drying her eyes with Dan’s handkerchief, “when he did not hear from you in London he went down to Blackheath with Inspector Tenson of Hampstead. They saw the local inspector and called at Lord Curberry’s house, after what Mr. Laurance told. But already a policeman had been summoned by the servants. Lord Curberry was dead of poison, and they found his confession saying how he had taken it because he believed that his connection with the Society of Flies was found out. Then the servants explained how Queen Beelzebub had come in an aeroplane —”

“They did not call her Queen Beelzebub — the servants, I mean,” said Dan, who had heard the explanation before but was glad to hear it again told in Lillian’s soft voice.

“No. They did not know who she was, as she was cloaked and veiled. But they told Mr. Laurance that you had declared this veiled lady had murdered Lord Curberry — that wasn’t true, you know.”

“True enough in one sense,” interrupted Dan quickly, “seeing that she drove him to suicide. Well?”

“Well, then, Mr. Laurance guessed that she was Queen Beelzebub and wondered where you were. He went to the shed where you kept your aeroplane and heard that you had followed her. Those at the shed thought that it was a race.”

“It was,” said Dan grimly, again, “and I won.”

“Mr. Laurance guessed that you had followed her all the way to Sheepeak, although he fancied, and indeed hoped, that both aeroplanes had broken down. He dreaded lest you should get into trouble at Sheepeak.”

“Which I certainly did, although not quite in the way Freddy expected.”

Lillian laughed at the memory of his escape, and rubbed her soft face on the sleeve of his coat. “Mr. Laurance told the police all about the matter, and they wished to telegraph to Thawley, so that the police there might go over to Sheepeak. But Mr. Laurance stopped them, as he fancied you might have been taken captive by Queen Beelzebub, and that if such a move was made, she might hurt you.”

“She intended to hurt me very severely. And then Freddy heard from the police about those numerous telegrams all in the same words, calling thirty people to Sheepeak. It was the similarity of the messages that made the telegraph authorities suspicious and when the police came to ask — knowing where Queen Beelzebub lived from Freddy — they were shown the telegrams.”

“But by that time all those who got the telegrams had come north,” said Lillian, quite excited, “they all went up by the early train.”

“Yes, and the police, with Freddy, followed, delaying action until such time as they thought they could collar the whole gang. By Jove, they just came in time. Freddy was a fool to tell you that I was in The Grange.”

“He was not quite certain, and only thought so because the wrecked aeroplanes were found in the field near the house. Oh, Dan,” Lillian put her arms round her lover’s neck, “Mr. Laurance told me how thankful he was when he saw you running along the road and knew that you had escaped.”

“He might have been thankful also that I caused him and the body of police to halt,” said Dan, quickly, “if they had not, every one would have been blown up. As it was, I very nearly got smashed by the falling sticks and stones and what not. There must have been tons of dynamite in the cellars of The Grange.”

“Who do you think put it there, Dan?”

“Queen Beelzebub, of course. She said that she had made everything ready against possible discovery, and warned poor Mrs. Jarsell that she would have to commit a last crime. Crime, by Jove! Why the best day’s work the woman ever did was to blow up that gang of devils.”

“I suppose Mrs. Jarsell did blow up the house, Dan?”

“Of course she did. Her heart softened for some reason, and she pushed me out of danger. Then she must have gone straight down to the cellar, and set a light to the stored dynamite. The explosion happened so quickly after I was free that I am sure she acted in that way. It was certainly efficacious, for not one of the blackguards, either men or women, remained alive to be hanged.”

“Well, that was a good thing,” said Miss Moon, with a little shudder, “you know that their relatives would have been disgraced?”

Dan nodded. “Quite so, and the names have never become public. This person and that person and the other person disappeared from various neighbourhoods and from various family circles. But when the relatives read about the explosion in Hillshire and Freddy’s brilliant account of that i............
