"You hold strong cards, Mr. Arnold Greatson," he said, "but I see their backs only. How do I know that you speak the truth? From whom have you learnt the story of this young lady's antecedents?"
"From Mr. Grooten," I answered boldly.
"I do not know the name," the Baron protested.
"He is the man," I said, "who set Isobel free!"
The Baron said something to himself in German, which I did not understand.
"You mean the man who shot Major Delahaye?" he asked.
"I do!"
"Then I would to Heaven I knew whose identity that name conceals," he cried fiercely.
"You would not dare to publish it," I answered, "for to do so would be to give Isobel's story to the world."
"And why should I shrink from that?" he asked.
