Knowlton arose. "Don't bother about that now, Ted," he said. "I know all about the Texas formula—it's all right—do you get me?"
"I think I'd go, Mr. Knowlton," Helen said. "Let me tell him all by myself."
Knowlton bowed and shook her hand. Then he came over to me and offered his hand to me.
"Ted, I'm not much of a talker; this is just to tell you I'm glad."
I took his hand, since he seemed to wish it, and he left the room. I looked around at Helen: "Why did you come to me at the laboratory last night in mediaeval dress when Prospero was trying an incantation?"
Her face clouded, and she hastened to me, laying her cool hand on my forehead.
"Hush, Teddy, sweetheart," she put her face close to mine. I could feel that her eyelashes were wet.
"It was the formula—not an incantation," I went on—"it must have been the signs of the Zodiac that confused me."
"Teddy, do you know me?—it's Helen," she kissed into my ear.
"I know, dear, I know," I said. "I love you, Lady Grey Eyes."
