Mia Thyme is an agent with OCT-U.
Rather, she will be, once she mostly stops working her previous occupation with is a call-girl. Escort, if you would. That is what she is doing when we meet her in the first recorded adventure. She is one of the top money-earners for Miss Stephanie and as we encounter her, she is pondering what age she will be that night. 26 is what she is in the mood for but then she is told the client is expecting twenty-two year old 'immature, unaware Miranda again'. She might not be thrilled with it but the client does not question it and it's her job 'to fulfil their fantasies'.
It is in the capacity that she will run into a couple of very interesting fellows, one who turns out to be a very unpleasant, dangerous man and the other who surprises her by being a good guy when she was thinking something else. And in the process she will be offered a chance to leave her profession, which she was truly wanting to do, and become part of the Organized Crime Taskforce Unit.
By the organization's name, it is plain to see that it has a crime-fighting mission but in order to achieve the goals of catching a particularly bad man, i.e., one of the fellows mentioned above, they need someone of her ... experience. So they approach her and the dilemma for her is whether to join them or not. What makes these adventures fit into this compendium is that the man in question has moved far outside the normal criminal boundaries and is planning something far worse for her native Australia.
Before she can have a chance of success in the undercover work she will be doing, she has to train in matters other than the one she is already proficient in. Once that is done, she is ready for action.
