"It is not so dreadful or so full as I should like it to be," said Dan, in his calmest manner, "but there is sufficient set down to warrant the interference of the authorities. If that confession comes into the hands of the Scotland Yard officials, they can lay hands on the gang;" he was bluffing when he said this, as he was not quite sure if Curberry had not let Mrs. Jarsell know that the confession--as Curberry thought--had been destroyed. "I think the police should know," said Mrs. Jarsell, rising. "Thank you for nothing," said Dan, following her example, "but, if I move in the matter, I run the risk of death. Besides, I may accept the offer of the society. Who knows?"

"Don't do that," implored Mrs. Jarsell, so earnestly that Dan was convinced Curberry had not told her of any confession, "it's so wicked."

"Perhaps it is. However, if the society leave me and Miss Moon alone, the confession won't be opened and the gang is safe. Otherwise----" "Otherwise the whole association will be exposed to the danger of arrest," said Mrs. Jarsell, lightly, "well, it sounds all very dreadful to a country lady as I am. I wish you had not told me. Why did you tell me?"

"Because," said Dan, ironically, "I look upon you as a friend." Mrs. Jarsell's face cleared and she smiled. "I am your friend," she said in an emphatic way, "and, believe me when I say that I am sure Miss Moon is safe."

"Thank you," replied Dan, agreeably, "I am sure also." Then they parted with mutual compliments, smiles and handshakes.

CHAPTER XVII

[AT BAY]

When Dan left Mrs. Jarsell he was very well pleased with the promise she had given concerning the safety of Lillian. He fully believed that she, in her role of Queen Beelzebub, would keep that promise faithfully, if only because her own interests demanded such honesty. The fact that the confession of Penn was in the hands of a third party, to be made use of should anything happen to Miss Moon, prevented the Society of Flies from carrying out the threat made to him at the secret meeting. To save their own lives, the members would be forced--much against their will no doubt--to spare those of Lillian and himself. Dan chuckled at the way in which he had circumvented the deadly organization. But he had only scotched the snake; he had not killed it, and, until he did so, there was always that chance that it would strike when able to do so with safety. But, while Penn's confession remained in Laurance's hands, all was well. One thing struck Halliday as strange, and that was the persistence with which Mrs. Jarsell kept up the comedy of having-nothing-to-do-with-the-matter during so confidential a conversation. She knew that Penn had been a doubtful member of her gang; she knew that he had been despatched--as Dan truly believed--because he was not to be trusted, and now she knew that he had left a confession behind him, which was in the hands of her enemies. Also, she was aware that the man who spoke to her had read the confession and must have guessed that her name, as Queen Beelzebub, was mentioned therein. This being the case, it is to be presumed that she would speak freely, but, in place of doing so, she had pretended ignorance, and for his own ends he had humored her feigning. Either she doubted that such a confession existed, or she guessed in whose possession it was, and intended to regain it. "Queen Beelzebub knows well enough that Freddy is my best friend," thought Dan, as he returned to the Peacock Hotel, "and it would be reasonable for her to believe that he had Penn's confession, which is certainly the case. I should not be at all surprised if Freddy was inveigled into a trap as I was, so that he might be forced to surrender the document or rather what remains of it. If that were managed, Queen Beelzebub would revenge herself on Lillian and on me, since there would be nothing left to shield us from her spite. And, in any case, Freddy is in danger, as I am certain she guesses that he holds the confession," he mused for a few moments, and then added, aloud, "I shall return to town at once and see him." The more he thought the more he saw the necessity of doing this. Mrs. Jarsell's first move to counterplot him would be to seek out Lord Curberry and learn what she could, relative to what Penn had left behind him. Certainly Curberry would assure her that he had burnt the confession, in which case Queen Beelzebub would think that she would be free to act. But Halliday believed she was of too suspicious a nature to be quite convinced that he had only bluffed. Before taking any steps, she would decidedly ascertain for certain--although in what way it was difficult to say--if there really was any compromising document in Laurance's hands. To do so, she would, as Dan had thought a few minutes before, set a trap for him, and browbeat him into stating what he knew and what he held. Therefore, for Freddy's sake, it was necessary to go to London, and report in detail the conversation on the moor. Then the two could arrange what was best to be done. They were dealing with a coterie of daring scoundrels, who would stop at nothing to secure their own safety, and it behoved them to move warily. "We are walking on a volcano," was Halliday's concluding reflection. Of course, as it was useless to alarm the ladies, Dan said nothing of his meeting with Queen Beelzebub on the moor. However, on being questioned, he confessed the sudden thought which had sent him out of doors, and both Lillian and Mrs. Bolstreath agreed that it was entirely probable that Mrs. Jarsell did travel in up-to-date aeroplanes, like a mischief-making fairy. Then, in turn, they told him that Mildred had stayed for quite a long time and was altogether more charming each time she appeared. She suggested many trips and Mrs. Bolstreath was inclined to stay at Sheepeak longer than she intended, in spite of the near menace of Queen Beelzebub. Lillian was delighted with the lovely scenery, so gracious after the drab hues of London. "I don't see why we shouldn't get a house here after we are married," she said to her lover, "one of those delicious old manor houses of faded yellow stone. I could live quietly with Mrs. Bolstreath, while you ran up to business on your aeroplane."

"And all the time you would be fretting lest any harm came to him," said the chaperon, shaking her head, "besides, my dear, when you are married, you won't want me to be with you."

"Dear Bolly, I shall always want you, and so will Dan."
