I was writing a creepy scene where my main character walked through a rather rundown neighborhood in London, England. I had never been to this neighborhood in my life. The last time I was in England, I was twelve and nowhere near this place. So to research I found a walking tour on the internet. It was just visuals, but it gave me a good impression of things. Then I read articles about the neighborhood, just a couple, for flavor. I found out about how the police handled things and what was socially acceptable. After that I picked one image for each of my senses to work into my scene. Then I plotted the whole thing out.
I think the resulting scene is one of my best works. One of the people in my critique group said, “I can really tell you’ve been there.” That made me happy. So bring the techniques of two truths and a lie into your work and see just what it can do.
