Thunderstorm

Emily was late. That was the first clue Derek had that something was wrong. Emily was rarely ever late. For her to not show up on Thursday night, and then to follow it up by being late for work.

Something was definitely very wrong. But she was still not answering her phone, so Derek had no idea what it could be. 

Had she fallen ill? Had something happened to her mother? Or maybe she had been robbed and that was why she was not replying to anything. Did that mean that he had to call the police?

Or maybe phone in to different hospitals to see if she had been admitted. 

Derek was just seriously beginning to consider calling the authorities when there was a knock at his door.
