Cathy Shadow's Doing It For Real, it's from Paul Voodini but while he may have wrote it down it's content is from another. Cathy Shadow is the pseudonym of a reader Voodini met a psychic fair. Which is important, as once you read the thing you may be tempted to balk at your purchase, but these are techniques used by a real worker as convencer of genuine power. She's someone with no magic or mentalism background and as such these demonstrations lack what some would call "the works" most of it boils down to real intuition. Which Voodini has long claimed a belief in. So if you're looking for the next big magic trick you won't find it here. While these pieces can definitely be use as part of a larger routine, I also like the suggestion that doing these causally will help you better understand the thoughts, feelings, and emotions experienced by someone who is actually psychic. And remember that a fail now and then can make you seem more legit and you can always follow up with a sure fire hit.
