|The Bloody Book
This is a digital recreation of the book soaked in blood which mysteriously appeared in the stacks at the Miskatonic Library. Written in blood were the words "Red Lenses," and a splash of blood obscured the opposite page. When the Amsbarys looked at the page through the red lenses in the spectacles, they were able to read a message which was previously invisible.
If you have a red piece of glass or transparent plastic, like the kind in old-fashioned 3D glasses, you can test this effect for yourself by looking at the image below through a red filter. If you don't have one, click the MORE button to the right to see how the pages look through Hosiah's spectacles.
