Do you love mystery stories, such as the Sherlock Holmes stories and those of Edgar Allan Poe and Agatha Christie? Do you ever yearn to be a good writer of mysteries, or just like to read them and know about how they're written? Carolyn Wells was a prolific author of mystery novels. In this detailed book, she teaches the history, types, principles, devices, plots, and structures of mystery writings. She gives advice to would-be authors of this genre, including ghost and riddle stories as well as detective and crime mysteries. This is virtually a crash course in creative writing of the mystery story. But also very interesting for readers of crime and mystery, not just writers.
