“And Marj’s plans always work!” exclaimed Ethel, admiringly.

“And—your plan—involves just girls?” asked John, in a disappointed tone.

“My plan,” announced Marjorie, “involves at least three people—and maybe more—myself, and my brother, and another boy!”

“Bravo!” cried Jack, grasping Marjorie’s shoulder in approval. “I’m with you to the end, Sis!”

“And so am I!” added John, quietly.

CHAPTER XVI
ANOTHER DISAPPEARANCE

It was not until the following day, when Marjorie faced a free morning, that she had an opportunity to go over the events of the previous day and weigh their significance. Then, with the excitement of the picnic behind her, she was able to think calmly.

The more she thought of the strange voice she and Ethel had heard in the cellar, the more anxious she was to learn its source. Now she felt angry with herself for running away; she wished that she had accepted the boys’ offer to return immediately and explore the cellar. It had been ridiculous to allow such an opportunity to pass.

She took her fancy-work and went down on the porch, hoping that Ethel, who was also free that morning, would join her. She longed to talk the matter over with her, and to tell her of the plan she was formulating.

She did not have to wait long, for in a few minutes Ethel appeared, with two or three magazines. But Marjorie had no intention of allowing her to read.
