What mattered now was to understand the mystery that lay ahead. I glanced briefly at Dr. Allen, who, indifferent to the interruption, was using a magnifying glass. His attention was focused entirely on our unusual guest, who was engrossed in a puzzle, as if trying to decipher the secret of his existence.
