THE LAB

After putting away the important documents I kept in the desk’s drawer, it was time to enter the Laboratory!
I've never left the door open, there are too many stored items that pose a risk to health, so the Laboratory’s door is closed by an electronic device.
To enter the Laboratory, all I had to do was look through the glass at a set of vials that I had strategically organized, it was all I needed to remember the code in case I forgot it!
