“My God! I knew it!”
“But, of course, you know that I had nothing to do with any attack on a man in whose house I was a guest,” he went on rapidly. “The whole thing is a horrible mystery to us all. Every man in our crowd was in the ballroom dancing.”
“How did you know that?” John interrupted sharply.
“Because I counted them as they entered.”
“You counted them?”
“Yes.”
“Then you were in command of the crowd?” Billy hesitated a moment, and said:
“Yes!”
John drew a deep breath and turned his head away in anguish.
