“That is where Mr. Ives’ library and office are, Peggy said, and I think that she mentioned a safe built into the rock. She said that was why he keeps everybody away from that part of the house.”

“Oh, he does, does he?”

“So Peggy said. She says it’s no temptation to her to go near his ‘old office.’”

Sarita smiled. “Peggy has turned out to be the most enthusiastic member of our ‘triumvirate.’ Do you like her mother?”

“I don’t know what to think of Mrs. Ives. She is lovely to us and she seems to think a great deal of Peggy, if she does turn her over to other people. Perhaps she has to. Do you remember Mrs. Peacock? She didn’t do a thing but preen her feathers and play bridge and golf till the crash came; then she gathered up her kiddies from various schools and went to work to take care of them.”

“Yes. It’s hard to tell about the society women.”

The girls rose as they saw Peggy tripping down the steps with a picnic basket in her hand. They joined her and went toward the path which led around into the rocks. They crossed the path by which they had entered the grounds from their own and the Ives’ woods, crossing also the rocky way with the steps which led down to the dock where the Ives’ yacht was supposed to stay.

On a narrow ledge to their left they had need to be careful, but it led to a small cave which they had discovered before. It was not like one hollowed out by the action of water, but more like a space in the midst of rocks which some giant had been piling, one upon another. There were cracks and fissures, too, and the retreat was large enough to be interesting.

“I’ve got sandwiches and doughnuts, pickles, some shrimp salad, and a blueberry pie,” Peggy announced, “and there is some lemonade in the ‘icy-hot.’” She swung the basket to the rocky floor as she spoke and sat down beside it.

“You are all hot with climbing and carrying that basket,” sympathetically said Leslie. “You should have let me carry it part of the way as I wanted to.”
