"Girls of my generation don't have hysterics," I taunted her. By the dyed hair and vestiges of rouge and powder which streaked the battered face I guessed that a sneer at her age would sting like a wasp. I wanted to rouse the woman's temper. If she lost her head, she might show her hand!

"You'll have worse than hysterics, you fool, before I finish," she snapped. "I'm going to make Roger Fane acknowledge me as his wife and give me everything I want—money, and motor cars, and pearls—and, best of all, a position in society. I'm tired of being a free lance."

"He won't do it!" I cried.

"He'll have to—when he hears what will happen if he doesn't. If I can't live a life worth living, I'll die. Roger Fane will go off this yacht under arrest as my murderer."

"You deserve that he should kill you, but he will not," I said.

"He'll hang for killing me, anyhow. You see, the more motive he has to destroy me, the more impossible for him—or you—to prove his innocence. Do you think I'd have told you all this, if any one was likely to believe such a cock-and-bull story as the truth would sound to a jury? But I'm through now! I've said what I came to say. I'm ready to act. Do you want a row, or will you go quietly to the door of Roger's cabin (he must be there by this time) and tell him that his wife, Linda Lehmann, is waiting for him in your stateroom? That'll fetch him!"

I had no doubt it would. My only doubt was what to do! But if I refused, the woman was sure to keep her word, and rouse the yacht by screams. That would be the worst thing possible for Shelagh and Roger. I decided to go, and break to him the news with merciful swiftness.

If I could, I would have turned a key upon the creature, but the doors of the Naiad's cabins were furnished only with bolts. My one hope, that she'd keep to my room, owed itself to the fact that she was too drunk to move comfortably, and that, despite her bluff, the best trump she had was quiet diplomacy with Roger.

Softly I closed the door, and tiptoed to his, three staterooms distant from mine. My tap was so light that, if he had gone to sleep, I should have had to knock again. But he opened the door at once. He was fully dressed, and had a book in his hand.

"Something has happened," I whispered in answer to his amazed look. "Let me come in and explain. I can't talk out here."
