“Good girl.” Vicki sighed. “I’d much rather you’d fly out of here with me in the morning. It would be surer and safer.”

“I—I can’t.”

“Well, the morning you hear the telephone signal, you’re to meet me at noon. Promise, Lucy?”

The girl took a deep breath. “Promise. But I’m scared.”

“I’ll come back as soon as I can.”

They whispered good night and Lucy crept back to her room.


CHAPTER X
The Signal

Vicki’s departure the next morning did not go well. For one thing, Mrs. Heath was suspicious when Vicki “repaired” the plane engine. “So easily?” she said—and Vicki wondered how much the woman guessed. For another thing, Lucy was fearful again this morning when Vicki hinted, “It’s such a fine, clear day. Just come for a little flight, Lucy.” One look at Lucy’s face showed she longed to leave.

Mrs. Heath said quickly to Lucy, “I’m not feeling well again this morning. Please don’t leave me alone.”
