"You were not here when I entered," the visitor said, "and I took a seat in that comfortable arm-chair. The warmth of the fire affected me, and I permitted myself to fall asleep."
He indicated, with a sweeping gesture, the big pulpit-backed arm-chair. Olga started and cried out:
"That chair was empty; I remember quite well, when my husband was here. There was no one in it, I am absolutely certain."
Karl was so strangely affected by the stranger's presence that he did not notice Olga's agitation. The other regarded her with his expression of cynical amusement, bowed gravely and said:
"Then I was mistaken, madam."
"Won't you sit down?" Karl said. "Allow me to present you to—but I can't remember your name."
"It does not matter," the other said with an expansive outward gesture of his restless, eloquent hands. "I am a philanthropist, traveling incognito. You may call me anything you like; call me Dr. Millar."
"Dr. Millar," Karl repeated, seeming for the first time to have some doubt as to the character of his guest.
"Oh, you may rest assured my social position is beyond question," the stranger said, as if divining his thought.
