Before Olga's door Mrs. Hellinger was seized with a paroxysm of despair.
"You knock, doctor," she sobbed, "I cannot."
The old man knocked.
All remained quiet.
He knocked again, and put his ear to the keyhole.
As before.
Then Mrs. Hellinger began to scream:
"Olga, my beloved, my dear child, do open--we are here--your uncle and aunt and old uncle doctor are here. You may open without fear, my love."
The physician pressed the latch; the door was locked. He looked through the key-hole; it was stopped up.
"Have the locksmith fetched, Adalbert," he said.
