I’ve gone through many books and websites researching the craft of mystery writing and also just research for mysteries and crime in general. Here are some of my favorites.
1. Writing and Selling Your Mystery Novel by Hallie Ephron
2. The Writer’s Guide to Weapons by Benjamin Sobieck
3. Now Write! Mysteries by Sherry Ellis and Laurie Lamson
4. Police Procedure & Investigation by Lee Lofland
5. Book of Poisons by Serita Stevens and Anne Bannon
6. Forensics by D.P. Lyle
1. Writing World – They have a great mystery section.
2. Writer’s Digest – A well known site that has articles about writing mysteries and thrillers.
3. Mystery Cozy – Not really updated anymore, but a great place to find other resources.
