"There's everything upstairs," said Pat. "It's all there, all Nick's father's equipment."
"Not tonight! That's final."
The girl's manner changed again. She turned troubled, imploring eyes on Horker. "Dr. Carl," she said plaintively, "I can't leave Nick now." She seized the arm of the silent, dejected youth, who had been standing passively by. "I can't leave him, really. I'd not be sure of seeing him again, ever. Please, Dr. Carl!"
"If these frenzies of yours," rumbled Horker, "are so violent and malicious, you ought to be confined. Do you know that, young man?"
"Yes, sir," mumbled Nick wretchedly.
"And I've thought of it," continued the Doctor. "I've thought of it!"
"Please!" cried Pat imploringly. "Won't you try, Dr. Carl?"
"The devil!" he growled. "All right, then."

"Damnation!" he exploded. "Prussic acid—or cyanide! What in—" He caught sight of Pat's tragic eyes, and suddenly replaced the container. "Pat!" he groaned. "Pat, Honey!" He drew her into the circle of his great arm. "I'll help you, dear! All I can, with all my heart, since it means that much to you!" He groaned again under his breath. "Oh, my God!"
