Unbelievable! Here I am, having written a short story that effectively put my detective novel on hold for a week, back into the swing of writing on the second night of restarting my project, and I suddenly realize I've made a massive omission: I don't know what the murder victim did for a living. Or anything else, really, about them, save for the fact they got murdered.
But that's OK; I'm inventing that now. I'm actually quite glad I didn't over-characterize this person at the start. Yes. I'm glad I concentrated on plot rather than character. I'm sure it will help keep things fresh.
