And suddenly I had a curious intimate premonition of danger. I had heard nothing, but I swung round instinctively. A shadowy form had crept up behind me. As I turned, it sprang. One hand gripped my throat, stifling any cry I might have uttered. I fought desperately, but I had no chance. I was half choking from the grip on my throat, but I bit and clung and scratched in the most approved feminine fashion. The man was handicapped by having to keep me from crying out. If he had succeeded in reaching me unawares it would have been easy enough for him to sling me overboard with a sudden heave. The sharks would have taken care of the rest.

Struggle as I would, I felt myself weakening. My assailant felt it too. He put out all his strength. And then, running on swift noiseless feet, another shadow joined in. With one blow of his fist, he sent my opponent crashing headlong to the deck. Released, I fell back against the rail, sick and trembling.

My rescuer turned to me with a quick movement.

“You’re hurt!”
