Doris Fein is a part-time agent with the IGO.
I had originally classified her as an adventurer but that is a wildly misleading description. It does fit, sort of, in that Fein absolutely loves adventure. She adores a mystery and will throw herself totally into finding the solution so in that regard she is an adventurer. She also loves her creature comfort and really has never yet dealt with hardship when we first meet her so that is a couple of points in the other direction.
I chose instead to go with her as a part-time agent for the Information Gathering Organization (IGO) which will on several occasions ask her to do a little something for them. It strikes me that she does not completely trust them but since she loves her country and wants to be of help, she complies with the request. Naturally being the adventurous short with an insatiable curiosity, that opens many doors into danger.
Our first encounter with her is when she is still in high school in her home town of Santa Amelia. She is on the school newspaper along with her close friend, Larry Small. It is Small who is the main focus of the first adventure we find Fein in but Fein's role is a vital one and clearly shows how inquisitive she is not to mention how take-charge she can be.
From the next adventure on, Fein, having graduated, is on her own to go wherever and do whatever she wants and a few times that puts her right where the IGO needs someone to be (well, once or twice they nudge her in the right direction).
Fein stands 5'4" and weighs 155 lbs which puts her with "a teensy weight problem" she has had all her life. She also complains a time or two about having mousy brown hair (images shown of her do not agree) but descriptions for others indicate her complexion is nearly flawless and her teeth perfect and for all her perceived physical issues, she always seems to have some good looking fellow or another interested in her.
Fein describes herself as "something of a feminist" which she explains means she does not expect guys to hold her chair or open doors for her and she most certainly does not take to being patronized, something which happens all the time and gets a rise out of her. When a man she was talking to foolishly referred to her as 'honey', she responded sharply, "If you don't want to be called cutey-pie, don't call me honey."
The adventures of Fein take place in the late 70's and early 80's, long before cellphones and social media.
An agent "cannot outthink intuition".
