There is an 8th spectrum, a spectrum of light, which is unknown to man. There are invisible plants, animals and even creatures similar to Humans, they can see us, but we can't see them. What happens when we meet? Does this explain ghost/poltergeists?

Do these creatures have body heat just as we do? Do these creatures help magicians who do real magic tricks? Who are these creatures? How can you see one? What if the creatures in The Secret Spectrum were like chameleons, could they reveal themselves? All this and more will be thoroughly covered and fully explained in the story "The Secret Spectrum".
