Wolfgang smiled and stepped forward. "Hi. I'm Wolfgang." He looked around at everyone. "You probably remember Eric Caldwell?"
Faces went pale, and there were a few nods from the assembled group. Wolfgang continued, "I'm a private investigator, and I was hired by his wife to figure out what happened to him. That's my goal."
also the passage: They shook, and slowly, the blood drained from Wolfgang's face.
Does it mean that he knows he done it (simply put) , was he a party to it? or was he being forced to ignore it? or is he protecting someone else?, maybe Wolfgang picked up on something else entirely which does not relate to the killings but something else sinister?
Love the story so far.. keep going, I'm a fan
