“Well, it’s based on this idea: whoever they are that want to frighten us away, they plan their attacks for only the times when we girls are alone in the house. Evidently, then, there is no hope of using the boys to help catch them. Neither do I think there is any chance of our doing anything, against men; we’d only get into trouble. So our one salvation lies in getting two or three of the boys to disguise themselves as girls, and go after them.”

“Splendid!” cried Ethel, approvingly. “But wouldn’t they recognize their voices?”

“Yes, if it is necessary to do any talking. I thought we might work out some such scheme as this—have Jack, disguised as a girl, and me sleep all night at the house; and have John and maybe one or two of the others,—either hidden or disguised—outside. I really haven’t worked out the details of the plot a bit, because I thought Jack and John could do much better than I could.”

“It’s wonderful!” cried Ethel, in growing admiration. “I’m sort of jealous of you, though—being the only girl—”

“I’d include you, Ethel, if I thought it were wise. But it seems to me we better not have too many, and of course it would be best for me because Jack is my brother. But we won’t decide anything definitely until I talk it over with Jack and John at the tea-house this evening.”

The girls continued to discuss the subject until Marie Louise and Florence came up on the porch, and then they dropped it for discretion’s sake. The whole effectiveness of the plan would be lost if the disguise were to be common knowledge.

At luncheon the scouts all asked Marjorie what she intended to do in regard to the warning she had received.

“I don’t know yet,” she replied, truthfully. “I want to talk it over with the boys and make some arrangements for staying again all night at the tea-house.”

“No! No! Marjorie!” cried Marie Louise, aghast at the idea. “Oh, please take the warning seriously, and stay away from there at night!”

Marjorie smilingly shook her head.
