Decided I wanted to do a series of minimalist chemistry Sherlock graphics. I apologize for the Cyclohexane molecule as I had to draw it myself, so sorry if I got it wrong. I’ve used the same colours as I have on my season/episode t-shirts because, as a synesthetic, that’s the colour each episode is. Either that, or it’s a dominant colour in the episode.
A Study in Pink
Tetrodotoxin—frequently abbreviated as TTK. A neurotoxin for which there is no known cure. Relevance to the episode: while not established as the method of death, I figured some sort of neurotoxin is probably what killed them. Admittedly, I have no training in that area.
The Blind Banker
Dichlorodifluoromethane—Freon-12. A common aerosol spray propellant. Relevance to the episode: spray pant was a definite feature of the episode, so I chose to use an aerosol rather than a pigment.
The Great Game
Pentaerythritol tetranitrate—PETN. An explosive, found in, among other explosives, Semtex. Relevance to the episode: Semtex was Moriarty’s apparent plastic explosive of choice in the Game, putting several victims in bomb vests.
A Scandal in Belgravia
Dopamine—a neurotransmitter responsible for pleasure, including as a result of love. Relevance to the episode: This episode dealt with love on a number of levels, and I personally adore the break-down of love as a chemical reaction from the ending of the episode. Probably the main factor in doing this graphic set.
The Hounds of Baskerville
Cyclohexane—a solvent. Relevance to the episode: Practically zero in reality. It was one of the few in the screenshot of the HOUND experiment records I was able to properly identify (that had a large image-size reference molecular diagram), though it and all the other ones I IDd had practically no medical purpose—most were solvents or used in (if memory serves) the petroleum industry. Why did my favourite ep have to be such a problem child?
The Reichenbach Fall
Calcium carbonate—a substance found in rocks and seashells. Relevance to the episode: One of the more common man-made uses of calcium carbonate is used as one of the ingredients in road paving. This includes sidewalks.
