I'm Sorry, Samantha

"I've been waiting for you to call, Ms. Larsson." The man's voice lacked the unusual calmness and warmth. Its hoarseness belied his exhaustion.

Samantha pursed her lips and had a bad feeling.

Sure enough, Selby said solemnly the very next second, "I'm sorry, Ms. Larsson."

He hung up as soon as he said that.

All Samantha could hear was the dial tone. Her eyes widened slightly and she calmly dialed the professor's number again. Unfortunately, she was greeted by a robotic notification that said, 'The phone number you have dialed has been switched off!'

Samantha clenched her phone tightly and decided to call Selby's secretary, only to receive the same notification...

She did not try to make any further calls and the light in her eyes dimmed suddenly.

Did he apologize because he had deceived her, or did he apologize because he regretted implicating her in all that?
