I'm a discerning reader, possibly to a fault. A factual slip can throw me out of a story and anything set in the country (or God forbid, on a farm) damn well better have been researched or I'm going to skewer it. In private, of course, but it will be skewered.
I researched for 18 months before writing A MADNESS SO DISCREET. I like to tell people I know so much about lobotomies I could perform one (I don't add that it's not a terribly delicate surgery). When it came to MADNESS, I dove in. Lobotomies, medical treatments for the mentally ill, the history of criminal profiling, the setting per 1890's culture, even speech patterns. I wanted to be thorough.
Originally MADNESS was supposed to have a connection to the 1893 Chicago World's Fair and America's first known serial killer, H.H. Holmes. That was scrapped later on for various reasons, but I had already done so much in-depth work framing the book for the 1890's that I didn't want to deal with a very big roadblock.
Lobotomies as we know them weren't in use until the early 1900's.
A part of my plot hinged on lobotomies and I'd read over a thousand pages concerning them, so I wasn't going to toss everything in the bin. Instead, I needed a feasible reason for a doctor in 1890 to have enough medical evidence to support performing something like a lobotomy... and I found that in the story of Phineas Gage.
I read another thousand pages in relation to Phineas before executing the scene in MADNESS where Thornhollow describes to Grace the function of the frontal lobe and explains the procedure he's about to perform on her.
Thousands of pages of research went into roughly three pages of that book.
In the same vein, I researched water for six months before writing NOT A DROP TO DRINK. I read about the history of water, about the projected water shortage, and even a book concerning - yes, really - water law. I can tell you things about water law that you really, really don't care about.
But in all of my thorough research concerning water I overlooked something vital.
Did you know that? I didn't.
It was something I didn't even think to look into. Most post-apocalyptic movies show plenty of roving bandits on motorcycles and people driving around in cars. Totally wouldn't happen. This was pointed out to me at a conference the year that IN A HANDFUL OF DUST (a book with, yes, people driving cars) released.
I'm not above telling you that it really, really bothers me that any scene in DRINK or DUST that involves gasoline is bogus.
That's how important facts are to me, even as a fiction writer. So important, that one of my favorite quotes from a historical figure found it's way into IN A HANDFUL OF DUST. I'm going to leave it here at the bottom of this post as well, and you will be seeing it pop in my social media feeds as we move forward this year.
