Mindful of recent topics, I'm posting this in an easily accessible forum
As I (finally) near the end of my novel, my idea for the second one is taking shape (probably still WF but edging towards Nicci French territory). However, MC is probably going to be a psychologist.
Now, I work for a mental health charity and over the years I've become pretty familiar with the jargon and I can even follow most of what our (flash git) consultant psychologist is on about and I could probably ask him for clarification of some points if necessary. I can also borrow reading material from work and swot up a bit, but I'm really wary of acquiring just enough rope to hang myself, knowledge-wise.
Any opinions on this? The novel isn't going to be centred on her work, but it will be important at various points - is this potentially too fraught with dangers to be sensible? If you've written about someone whose profession you don't have first-hand knowledge of, how deep into the subject did you go?
As always, any advice welcomed
