I'm a newbie, but I'm reassured by this committed and correct modding, thank you.
Poor Sarah, and her poor family. My heart goes out to them. My thoughts have turned a little to WC's reputation within the Met and his relationships with colleagues. I wonder whether any internal stuff that might have been a glimpse of a red flag will be unearthed. I'm basing this train of thought a little on how LE reacted and carried out the investigation to this conclusion. Was it conducted in a certain way because of his position and his knowledge, or because there was a crystalizing of something - perhaps innocuous, maybe not - that had gone before.
I have no clue, obviously, but WC apparently had potential or capacity for extreme violence and violent behaviour, and he's working at the heart of LE, with all of its resources and expertise. I'm not suggesting for one moment that police should somehow be able to spot a potential offender on sight, but years of working with someone, when you're trained and experienced in various fields of LE, makes me wonder about what internal stuff might emerge.
