"She did more than that," said Claudia, looking very sick and white. "She tried to implicate my father and Edwin when she knew they were innocent."
"Oh, that was a part of my game," said Lady Wyke, lightly. "But you know now why I went to buy a motor. It was to make Edwin's acquaintance. Then Neddy gave me the letter he had taken from the hall table, and I knew that I had the upper hand of your lover. I must say that, seeing how I could have ruined him, he was brave to stick to you, Claudia. As to that pirate Lemby----"
"That's enough," said Sergeant Purse, suddenly. "I have heard all that I want to hear. Now come to Redleigh Gaol."
"One minute," said Lady Wyke, staring across the water. "There is the aeroplane, sergeant. Won't you wait for its arrival, and let we say good-bye to the man I love, and for whose sake I have ruined myself?"
"No. Come along," and Purse laid his hand lightly on her arm, never thinking but what she would obey, "come to Redleigh Gaol."
"Death rather!" shrieked Lady Wyke and, handcuffed as she was, sprang down the path in a moment. How she kept, her balance was a wonder but keep it she did, and before the two on the cliffs could gather their senses together she was down on the beach. The aeroplane came nearer and nearer.
"She means to drown herself!" cried Claudia, and sprang in pursuit, while Purse, wholly taken by surprise, blew his whistle loudly.
At once three or four men came running from the coastguard station, and followed the sergeant down the path. But Claudia, determined to prevent her rival from escaping punishment, was already in pursuit. She soon dropped to the level of the beach, and scrambled over the boulders on to the smooth sands. Lady Wyke was speeding ahead like a swallow, but lingered when she saw Claudia at her heels. The girl got within touching distance of her, when the woman, with an insulting laugh, darted off again. Claudia followed unthinkingly, and almost before she knew what had happened, found herself in the middle of the fatal quicksands, which had been pointed out to her by Neddy.
Lady Wyke was already sinking fast, and laughing loudly. "I've got you; you are trapped! No Redleigh Gaol for me, and no Edwin for you! I'm not beaten yet, I'm not beaten yet!"
Claudia shrieked as she felt herself in the grip of the cruel sands. Purse and the coastguards uttered shouts of dismay, for it appeared to be impossible to save the two women. At once two of the men scrambled back up the cliff to get ropes and boards for the rescue. But all the time Claudia and the rival who had lured her to destruction were sinking deeper and deeper, Lady Wyke, in particular, going down swiftly, as she had ran on to the sands first. Claudia was following quickly. All at once both women heard the buzz of the machine, and looked up to see the aeroplane directly overhead. Edwin dropped swiftly downwards as he recognised the peril, and soon came near enough to recognise who were in danger. With a white face, but perfectly calm, he dropped the rope coiled on the pilot seat, and guided the aeroplane down a short distance above the heads of the two. Lady Wyke uttered a cry of rage as she saw Claudia grasp the rope, and cling to it for dear life.
