"The danger comes not from the sea! You will be a victim!"

The young man let the boat line fall from his grasp, a fierce light shone in his eyes, and there was a tremulousness, but not of fear, in his voice as he demanded:

"Who sent you to tell me this?"

"It matters not, you are doomed if you go on the yacht to-night! never again will your feet press the hard shore, but the waves will cast you up!"

"Who are you, miss, and why have you come to warn me?"

A moment the girl was silent. She hung her head and appeared lost in thought, but at length, looking up and fixing her magnificent blue eyes upon the young man, she said:

"I do not know who I am, but I do know that if you go out on the yacht to-night, you will never return till the waves wash your dead form to the beach!"

"You must have some reason for coming to warn me?"

"Yes; I would save your life!"

"Why are you so deeply interested in saving my life?"
