It’s that time in my writing year when the manuscript comes back to me with bloopers and queries marked up by the copy editor. Copy editors are essential people in the publishing business. They catch howlers and misspellings, they patiently insert missing commas. But sometimes they go a bit further and make stylistic suggestions and when they do that they cross my personal version of the yellow incident tape the police use to cordon off no-go areas. You can’t write a novel by committee. No-one tells me how my characters speak.
