“Aside from the—er—electricity in the air, was everything quite as usual?”

I paused for a long moment before replying.

“No,” I said candidly. “I think we were all a little nervous and uneasy on account of the heat and suffocating air. That is, I was. And Dr. Letheny—and Miss Day——”

“But not the others?”

“Well——” It was difficult to define that curious tensity I had felt in the air all the night. “No one seemed quite natural to me. It may have been only I who was a little nervous. I really can’t tell you anything definite.”

“Why did you say definitely that Dr. Letheny and Miss Day were unlike themselves?”

“Dr. Letheny is a rather quick-spoken man—when you know him you will understand what I mean. He goes on his nervous energy, is very high-strung and temperamental. He seemed especially explosive last night. And Miss Day was a little abstracted, tired, I think.”

“I suppose you talked—played bridge—had a little music?”

“Yes. All of that.”

“Any special topics of conversation?”
