Apologies in advance if this has been asked before, I couldn't find anything in search. Anyone who writes this type of mystery story/novel, I'd be interested to hear how much plotting you do in advance. My preference in general is to do a minimum amount of planning, and to just let things sort themselves out as I write, but I can't see how this will work for a mystery. So, how much plot do you have in mind when you start writing? Just the main details- the initial crime, the criminal and the investigator, or do you plan out all of the potential suspects, the red herrings, clues and so on? Cheers!
