A writer, speaking at a conference I attended, suggested interviewing key characters when it’s tough to decide on the direction one’s writing should take.
So, I asked a character for an interview. He turned me down. I asked again. Same result. Later, he called the police and filed a harassment complaint against me.
I wrote about the incident, thinking my problem solved. He sued me for libel. Acting on the advice of another writer, I killed the offensive character.
I may be just past the point of logic and believability.
