Clara I couldn't concentrate, I tried. I really tried. But my mind kept returning to the same place. Alexander. I couldn't feel at ease, not since my suspicions about him had intensified. I paced back and forth in my office, clutching my arms to my chest. I felt anxious, a horrible anxiety that had my heart racing since early morning. I looked at the documents on my desk for the fifth time. The copies Howard had given me—the dates didn't match, nor did the modifications. And then there was the engineer. "I warned Mr. Alexander not to use that elevator." I closed my eyes for a second. I needed something more, something that pointed directly at him, something more than just suspicion. I could still hear that phrase perfectly. I opened my eyes again and let out a shaky sigh.
