Dr. Littlejohn started and peered into the wan face lying back on the pillow. Its impassiveness reassured him.

“Why, perhaps--once or twice,” he returned slowly, falling back into his old position, “though rarely--very rarely.”

“Hush! Not yet!” The woman’s insistent hand had pulled him back. “Why am I here? Where is this place?”

There was no answer.
