Hi there! the effect is explained in FULL in the book. The DVD is a performance only piece plus an interview. Its very well layed out and explained so I don't think there will be any trouble with learning from the instructions. I can also recommend checking out Masterminds Volume 1 which is the same effect but Sinful is updated more.
