This question came up for me with reference to something on the EMWA e-list, and I'd love to hear what Crimespacers make of it. To cheat by repeating what I said there: Writing courses can teach the new writer about plotting and character arcs, how to use strong verbs and avoid excess adverbs, and a host of other techniques that separate the beginner from the pro. But what is voice if not something ineffable that springs from the depths of our individual creativity? It can't be faked. Can it be deliberately constructed?
