Fans of murder mysteries follow an unwritten code: don't give away the ending! Don't even talk about which clue is crucial or which suspects are red herrings.
We do this for the obvious reason that telling someone whodunnit makes the book less suspenseful for them. In many years of reading and chatting about these books, I've never heard anyone do this, and I hope I never do.
I wish I could talk about certain things my sleuth discovers because I think they might attract some readers, and, equally important, they might let other readers know the books are not for them.
Since this is just between you and me, I will say parts of my plots could have been ripped from the headlines. Oddly enough I did not have this in mind while I wrote them. Rather the headlines caught up with me.
I might also mention that a well-known publisher recently announced they will launch a new line of mysteries. Good for them! They also put out a list of requirements for authors wishing to submit: length, restrictions on sex and violence, etc. Again, good for them.
One of their requirements made me decide not to submit to them. They say it's alright to include characters who belong to racial minorities or who are gay so long as their identities do not create problems for them.
I do include such characters, but I am unable to imagine a world in which it doesn't matter if you're gay, or black, or Asian, etc. In my books, it matters.
If you don't want to read about such a world, please enjoy any of the thousands of other mysteries that share this publisher's world view. If want to see the world as I do, please check out my books on Amazon.
