Concept wise I am thinking about a Toreador of the not entirely usual sort. If acceptable?

Argus was ambraced after his war experience chosen not for his beauty or quality of his art but for his perspective. His early works consisted of art ( sketchings and photographs) depicting every day situations and kindnesses. Later video cameras became affordable and Argus who always loved cinema became a film maker and freelance reporter. He is especially for a Toreador a shy individual that enjoys observing others more then being the center of attention himself.
Most of his serious work he would post online under a pseudonym.

If you are ok with it he could be making a documentary about the people maintaining self help groups in Chicago?
I think it would be a nice way to meet our gangrel.
And cooperating with a detective always sounds like a great idea for a reporter.
