It was true that each night the girls had been disturbed by loud groans and the sound of gruff voices. Doris had wondered if Cora and Henry Sully were trying to frighten them, for certainly it was not the wind that they heard.
It was lonesome and gloomy in the right wing of the old mansion and the girls had come to dread the nights. They would have been less nervous if Wags had been permitted to stay with them, but he had been consigned to the shelter of the porch.
Several times Doris and Kitty had been tempted to tell the Misses Gates everything they had learned, but knowing how partial the two ladies were to Ronald Trent, they hesitated. It would be better, they decided, to wait for the plotters to make the first move.
Doris had wondered if Dave would visit her at the mansion but she had not dared to hope that he would come for at least a week. On the afternoon of the third day she was, therefore, greatly surprised when she heard the rhythmical hum of an airplane motor.
“I wonder if it can be Dave?” she exclaimed to her chum.
Eagerly they watched as the plane swept closer. Then Doris recognized the familiar craft and scarcely could contain her excitement. The monoplane circled low and Dave waved to them. Finally he dropped a note to Doris telling her that he intended to come to see her soon. After that he turned back toward the airport.
“I suppose he’s just out for a trial flight today,” Doris declared.
When Kitty was not looking, she carefully folded the note and placed it in her pocket for future reference.
The sight of Dave, distant as it was, gave the girls a slight touch of homesickness, and for want of a better occupation they decided to write back to their friends. They had the library to themselves, for as usual Iris and Azalea had taken their Bible with them to the third floor.
“Jake certainly would enjoy this place,” Doris commented as she sat at the desk with pen poised. “He likes mysteries and things that smack of the unusual.”
