"Not to London," interposed Mrs. Bolstreath, "we propose to visit some friends in Scotland." Lillian looked up in surprise, as Hartlepool certainly was not in Scotland, and she thought that Mrs. Bolstreath's geography was at fault. But a significant look from Dan showed her that he understood why the wrong address had been given. Mrs. Bolstreath, with too much zeal, mistrusted Mildred, although she had no cause to do so. Certainly Mildred, in perfect innocence, did she know the actual destination, might tell her uncle, who would assuredly tell Mrs. Jarsell, and, for obvious reasons, it was not necessary that Mrs. Jarsell should know where the city of refuge was situated. All the same, Dan did not think for a moment that Mildred knew anything about the Society of Flies. But he was beginning to fancy that Vincent had some such knowledge, as Mrs. Jarsell financed him, and that she would not do so, he was positive, unless she made something out of the matter. It was very convenient for Queen Beelzebub to have an inventor at her elbow who could construct swift aeroplanes. And it was at this point of his meditations that Dan jumped up so suddenly as to spill his tea. "What's the matter?" asked Lillian, making a dash at the cup and saucer to save breakage. "I've got an idea," said Halliday, with a gasp. "I must go out and think it over," and, without excusing himself further, he rushed from the room. "That's not like Dan," remarked Mrs. Bolstreath, uneasily, "he is calm and cool-headed as a rule. I wonder what is the matter?" "Oh, he'll tell us when he comes back," replied Lillian, philosophically. "I can always trust Dan." Then she turned the conversation in a somewhat heedless manner. "Do you like living here, Miss Vincent?" "Well," admitted Mildred, "it is rather too quiet for my taste. But I have plenty to do in looking after my uncle and his business. He depends so much on me, that I wonder what he will do when I get married." "When do you intend to get married?" asked Mrs. Bolstreath, curiously. She could not disabuse herself of the idea that, living so close to Mrs. Jarsell, and having an uncle who was helped by Mrs. Jarsell, the girl knew something about the Society of Flies. "Next year, the year after--I don't exactly know. It all depends upon my dear Freddy's success. We must have a home and an income. But I suppose we shall marry, sooner or later, and then Mrs. Jarsell can look after Uncle Solomon." "Who is Mrs. Jarsell?" asked Lillian, artfully and cautiously. "She is an old lady who lives at The Grange with another old lady, her former governess, Miss Armour. Both are charming. If you are dull here, perhaps, Miss Moon, you would like to meet them?" "Later, later," put in Mrs. Bolstreath, hurriedly, "thank you for the suggestion, Miss Vincent. Meanwhile, we wish to explore the country. It is a charming neighborhood, although very quiet in many respects."
