I am interested, holding this place and I'll edit with my character pitch when I have time.

[hider=Character Concept]
An Internal Security and Vetting agent who caught on to some "inconsistencies" of a rising star in MI5. She pushed too hard and too quickly and the investigation showed "lack of sufficient evidence" on her part, so the person was never questioned or investigated. She was "relieved" of her current job and re-assigned, moreso to push her down and suppress her. Eventually, a scandal revealed that the agent she suspected was a bad egg and was caught up in a lot of bad stuff, but she was never given credit and another agent was given the recognition she deserved. So she is very cynical of MI5, but she still does her job.[/hider]
