The realization of Millar's trick was like a blow in the face to Olga. She saw now how he had deliberately lied to her, in order that she would certainly repeat her confession of love to Karl. In what a bold, forward, disloyal attitude she had been placed! Her first impulse was of anger, and she ran toward the anteroom.

"Doctor! Dr. Millar!" she called wildly.

The door opened noiselessly and Millar stood bowing on the threshold.

"My—my letter!" Olga stammered.

"Madam, I beg a thousand pardons," Millar said suavely. "My only excuse is that some letters are better undelivered."

He drew from the inner pocket of his coat a letter, and with a smile and a sweeping bow handed it to Karl.

"However, I can now make reparation," he said.

Karl took the letter, looking wonderingly from Olga to Millar. He held it an instant in his hand and was about to open it, when Olga cried:

"Karl, tear the letter up."

Karl instantly obeyed her, tearing the envelope into small pieces.
