Query: Not For Serious Mystery Writers.

It is only 64-page long with images largely occupying every single page.It is probably enough for causal writers who would like to try writing a mystery story once in a while, but for serious writers who want to be published, this isn't one of the best sources to go for. There are far better books attacking this topic thoroughly. such asTelling Lies for Fun & Profit: A Manual for Fiction WritersandHow to Write Killer Fiction: The Funhouse of Mystery & the Roller Coaster of Suspense.
