A Man From the Past
Felix glanced at the display of his smartphone immediately after leaving Olaf Meiden's office. Of course, a new message was there barking its fangs at him. He didn't read it. It wasn't from anyone connected to his work. At least currently. And if Olaf found out that he was still in contact with this person, he would probably fire him.
Although it's not like Felix wanted to be pestered with these incessant text messages filled with pleas to meet.
The simplest solution would have been to block the number, but not the safest. There are some people you need to have under your surveillance even if it interferes with your personal life or work. As long as the messages are begging, you may be at ease, but if they start demanding, then you will have to be on guard.
