I think we all can agree that mysteries are hard to write.
Regardless of what category the story falls into-crime fiction, hard boiled thriller, or cozy mystery-the demands on the writer are steep and plenty. Readers expect a horde of red herrings; clues that can't be perceived as clues; a multi-layered plot that is slowly, sinfully, unraveled; tension and suspense being maintained throughout the narrative; a smorgasbord of entertaining suspects; and of course, a unique twist on how to commit a murder. If that doesn't make a writer want to power down their computer and break every number two pencil in sight, they aren't human. Or they're the reincarnated spirit of Agatha Christie.
