The Book

The Book is a mysterious text that The Man uses to create opportunities for his visitors to receive what the desire. During conversations with his visitors, The Man references The Book to see what task the visitor must accomplish to get what they desire and scrawls down the events that transpire as they attempt to complete their task.

Only two people that we know of have seen the contents of The Book, The Man and Doris.

At this point, little is known about the origins of The Book, but there is a brief mention of a third party that has some knowledge of it in the show's second season in conversations between The Man and Doris. The origins of The Book and the mysterious organization will probably be expounded upon if the series is ever picked up for a third season.
