Quick as a flash, she grasped the man’s felt hat, jamming it down on his head over his eyes. While he was trying to pull it off, Louise also wriggled from his grasp.

The two girls ran to the water’s edge. Their boat had drawn close to shore. Without waiting for it to beach they waded out over their shoetops and climbed aboard.

“Don’t either of you ever come here again!” the gardener hurled after them. “If you do—”

The rest of the threat was carried away by the wind. However, Penny could not resist waving her hand and calling back: “Bye, bye, old timer! We’ll be seeing you!”

“What’s the matter with that man anyhow?” asked the boy who rowed the boat. “Didn’t he want you on the estate?”

“On the contrary, he invited us to remain and we declined,” grinned Penny. “Just temperament, that’s all. He can’t make up his mind which way he would like to have it.”

Allowing the boy to puzzle over the remark, she busied herself pouring water from her sodden shoes. The visit to the estate had not turned out at all as she had planned. She had failed to talk with Miss Kippenberg, and it was almost certain that from now on servants would keep a much closer watch for intruders.

The only vital information she had gleaned resulted from overhearing the conversation between Sylvia Kippenberg and the gardener.

“She talked with him as if they were well acquainted,” mused Penny. “Miss Kippenberg must have thought he knew more about Grant Atherwald’s disappearance than he would tell. And she seems to be afraid the Law will ask too many questions. Otherwise, she wouldn’t have suggested getting rid of the alligator.”

One additional observation Penny had made, but she decided not to speak of it until she and Louise were alone.
