Descent Into Darkness Season 2 Episode 18

"There was also a curious point in the night where the good Mrs. Nichols showed us a book that she had picked up out of curiosity called something like Giant Women From Mars. While the book seemed to be pure drivel the jacket had the very eye symbol that we had been searching for. She mentioned that there were several books like this in a book store called the Minds Eye, which gives me another location in Boston to search for the members of the Church of Contemplation." - Lance Monroe, June 16th, 1921
