Suddenly Drexel paused. A tense excitement dawned upon his face.

His strange look drew Sabatoff to his feet. “What is it?”

Drexel tried to speak calmly. “Was not Borodin, when first arrested, held in some other prison?”

“Yes, in the Central Prison.”

“And the reason you did not know where he was, was because he had been secretly removed?”

“Yes.”

“These removals are common, are they not? Especially into a stronger prison?”

“Yes.”

“Is there a stronger prison in Russia than Peter and Paul?”

“None.”
