UNDER THE MICROSCOPE - PART THREE
________________________________________________________________
In part one of UNDER THE MICROSCOPE I wrote about the Clostridium Botulinum bacteria Sherlock discovers on Carl Powers shoelaces in TGG.
Part two is about the glycerol molecule Sherlock finds when he examines the residue left behind by the shoes of the kidnapper in TRF.
Part three is a comparison of that what Sherlock - and the audience - sees when looking through the lens of the microscope … and some musings about it.
The Great Game
Sherlock looks at Clostridium Botulinum … brightly colored in blue and green on a black background. As I mentioned in part one, bacteria on slides, viewed under a microscope would look most likely a bit different. Propably more similar to the picture on the right. (X)
What Sherlock actually looks at is a colorized picture of Clostridium Botolinum taken from the internet. I found a completely identical one on Microbe Wiki. And because Sherlock looks just at a picture …. nothing moves. It gives the illusion of something that is dead.
TGG is the case that will lead Sherlock to Jim Moriarty at the pool.
The Reichenbach Fall
In this episode Sherlock looks again through the lens of a microscope. And again that what he sees (although diminished in size) is coloured blue and green on a black background.
This time though it is not a motionless picture … the specimen on the slide are rapidly moving around. The audience is given the illusion that Sherlock is watching something that is very much alive.
Immediately after that shot, Sherlock identifies four chemical traces left behind in the footprints: chalk, asphalt, brick dust and vegetation.
When Sherlock starts working on the fifth sample he looks again into the lens of the microscope. Once more the slide is full of rod-shaped, rapidly moving specimen …. but this time they are coloured bright red …and just like the blue ones, they look very much alive.
At this moment Sherlock soflty murmurs to himself: ‘I … owe … you’
…. and he wonders what the fifth substance might be …. ‘it’s part of the tale’ ….
What Sherlock finds is … first glycerol and then PGPR (part two)
Summary:
In TGG Sherlock looks at a picture of bacteria:
- coloured in blue/green/black
- it’s not moving
- it doesn't appear alive
In TRF Sherlock looks at specimen of something that is:
- 1) coloured in blue/green/black 2) coloured in red/black
- the specimen on both slides are moving rapidly
- both samples seem to be very much alive
And something else that strikes me as rather odd is this:
In TGG Sherlock identifies a bacteria …. which is a living organism …. but strictly speaking - in this scene - it is dead, because it’s just a picture Sherlock is looking at. Well, maybe this should suggest that the bacteria in question is 20 years old and already dead? Is Clostridium Botolinum able to survive 20 years on a shoelace? I have no idea but maybe that’s not really the point. Maybe the important bit is that the use of an unmoving picture gives the illusion of 'death’?
In TRF Sherlock identifies at first chalk, asphalt, brick dust and vegetation. Glycerol seems to appear on the computer screen beside him. Appart from vegetation, none of those samples is a living organism and therefore wouldn’t move around. And I don’t expect vegetation to move either. But what Sherlock observes on the slides under the microscope … moves quickly and appears very much alive.
What might be the reason for including shots of those slides … full with brightly coloured, rapidly moving, obviously living specimen … into an analysis of chalk, asphalt, brick dust, vegetation and glycerol? They seem to have no meaning for the story. Sherlock deduces nothing from them. Additionally both shots appear just for a short second. Very easy to miss. So the reason why they have been included is probably not their impressive look either.
But despite of that, someone decided to include them and someone took the time to create those shots. What for? The plot of TRF wouldn’t change one bit if they weren’t there.
Maybe it’s the place where those shots appear that matters? And the colour changing from blue/green to an alarming red? After all, red is THE signal colour …. used to warn, to be cautious, to call attention to an imminent danger.
The first shot of blue/green specimen seems to mark the beginning of Sherlock’s analysis.
The second shot of the red specimen seems to be connected to Moriarty (IOU) and appears exactly before Sherlock deduces the glycerin molekule.
And this last sample will lead Sherlock to the abducted children and subsequently to Jim Moriarty on Bart’s roof. Definitely dangerous!

I leave you to your own deductions. Thanks @callie-ariane for the scripts.
