So I spent a while this morning doing research and deciding that I couldn't possibly write a steampunk Cthulu story for an anthology with that theme, then went for my daily medicinal walk. Lo and behold, I arrived home a few hours later with the whole of just such a tale in my head - main characters, voice, ending, first line, the lot.
But is it any good? I'm always suspicious when a story comes too easily. Appreciative, but suspicious. Mind you, I've only put down that first line so far (it was inspired by a rack of DVDs in front of a shop I passed - one of the titles was Contagion - crossed with something I then read about 5 minutes later on a community notice board). Possibly actually writing the story will throw up enough roadblocks to make me feel suitably tormented and subsequently less leery of it. :)
But now I really, really need to get writing again soon, rather than just thinking about it all the time. My muse has returned to duty, but alas, my writing oomph is still MIA.
