So, I am working on a mystery novel these days and could use some advice. I know it might not be the best strategy, but I do not write down my plot or map it all out before writing the novel. I know the general direction I am headed in, and have figured out most of the pertinent plot points, but I let little surprises pop up along the way, especially for the details. That way, the novel never becomes 'old' for me; it's a discovery as I write it, not knowing exactly what's about to happen. In summation, I do not have all the nitty gritty figured out. Now, the question I have is that currently, the police are trying to solve a serial murder, and they're sifting through leads and whatnot. Of course, they're at a deadend when finally, a useful lead turns up. In my current draft, the useful lead turns up in the second chapter. I know this is hard to comment on, but still, do you think that's too soon? Should I develop the characters more and let them wander before they get that lead? Or should I pen this down as is, and come back to it later? Thanks a bunch, folks.
