"I always had my doubts," said Halliday drily, "they were lulled by Penn's lies and reawakened when I found the scent at Mrs. Jarsell's. Now I know all about the matter. I place my life in your hands by telling you."

"Is it as serious as that?" asked Laurance uneasily. "Yes. Serious to me and to Lillian also. Read that." The journalist scanned the crimson typewriting, and his eyes opened larger and larger as he grasped the meaning of the message. "Where the deuce did you get this?" he demanded hurriedly. "I found it in my pocket when I got back the other night."

"Where from?"

"From the headquarters of the Society of Flies."

"There is a gang then?" asked Laurance, starting. "Yes. A very well-organized gang, presided over by Queen Beelzebub, the consort of the gentleman of that name, who is the god of Flies."

"Where are the headquarters?"

"I don't know."

"We may be able to trace the gang by this," said Freddy, examining the typewritten paper. "If Inspector Tenson----"

"If Tenson gets hold of that and learns anything, which by the way I don't think he can, from that paper, my life won't be worth a cent; neither will that of Lillian's. I might not care for my own life, but I care a great deal for hers. I want to have a consultation as to what is best to be done to save her from these devils."

"Well, you can depend upon my saying nothing, Dan. It seems serious. Tell me all about your discoveries." Halliday did so, starting with his visit to the cinematograph with Lillian, and his recognition of Mrs. Jarsell in the animated picture. Then he recounted his journey to Hillshire, and what he had learned from Mrs. Pelgrin and her nephew. "So on the face of it," concluded Dan earnestly, "I don't see how Mrs. Jarsell could have got to London. She didn't go by train and could not have gone by motor. Yet, I'm sure she was on the Blackheath grounds."
