"Yes," she answered, "Dick told you the story. You would not see the reef, but that the tide is low. But it is not that I wanted to show you. See!" and she stretched out her hand towards the rock pile of Norwithel.

"He is cutting the weed," said I.

"That is the pretence," said she. "But so long as he stays there no one can enter this house without he knows, no one can go out without he knows."

"Unless one goes in or out by the door I used."

"That door is within view of the Castle Down. There will be some man smoking his pipe, stretched on the grass of the Castle Down."

"You have never spoken to them?"

"Yes! They wanted nothing of me. They only watch. I know for whom they watch. I could learn nothing by questioning them."

"Have you asked Captain Hathaway's help?"

Helen smiled.
