Ann was startled. Still more startled to feel the almost irresistible link between them, drawing them together. "I'll remember, Thad," she murmured.

Carlyle slipped something from his pocket. "And just to make sure you don't forget," he said sternly, "you're going to wear this as a reminder. I found it in a wrecked ship, a long time ago. Like it?" He leaned forward to slip the thin silver chain about her neck.

Ann's eyes widened as she accepted the necklace. She held the tiny crystal heart in her fingers as Carlyle snapped the tiny lock.

"I've never seen anything like it!" she breathed. "So crudely cut, and yet every line so perfect. Thad, look! The color of it! There seems to be just a suggestion of pink in the very heart of it—"

Thaddeus Carlyle let the gem fall into his palm, so that the crystal contacted his silver ring. Ann gasped. The suggestion of pink was now a glowing atom of scarlet, as though the heart held one drop of blood. It throbbed and pulsed with life of its own. The heart grew warm against Carlyle's palm—

Suddenly the girl fell back against the chair.

"I—I'm so tired, all of a sudden," she whispered. "Almost too tired—to breathe. Take me—to my cabin—Thad. I think I want—to lie down."

Carlyle swore under his breath. "Fool!" he muttered. "I've been wearing you out with work, and excitement piled on that. You're going to bed, young lady. The ship's surgeon is going to have a look at you, too."

"No, I'm all right," Ann murmured. "Just—tired."

But Thaddeus Carlyle's strong arms were under her, now, and even as he carried her from the cabin she fell asleep. Looking down on her placid features, so like death, he felt a stab of remorse.
