I'm unique for a suspense author in that I don't have a specialty background. A lot of suspense writers used to be lawyers or crime beat reporters. I didn't even know a cop when I started out. I finally figured out that I could visit prisons - I just had to be willing to make the phone calls.
Having the opportunity to follow the market frequently gives you the opportunity to see if you need to reevaluate your portfolio. But reevaluating your portfolio shouldn't trigger a sell signal so frequently.
