Leo Boudreau's books have been out of print for a long time. Now that they are available again electronically, a new generation of magicians can learn and study the subtle methods Leo developed to produce true miracles. Some have said that his effects are the next best thing to real mind reading. I fully agree with this statement. The way he finds out which item the spectator selected is so subtle that it appears as if he is not doing anything. Here is a quote from Leo which Al Mann included in his introduction to Psimatrika:

"I can give a deck of cards to a person and tell him to secretly cut the deck as much as possible and then to deal three cards or more and I can tell him what the cards are! from across the room!!! (You got to be kidding Leo, I thought.) And I have a way of reading the backs of anybody's unmarked deck!!!"

Even if you never do any of Leo's tricks, because they don't fit your style, you will want to know how they are done. Otherwise, one day, somebody will fool you so badly with them that you will beg on your knees to find out how they are done.
Many of the effects Leo describes are based on what mathematicians call a 'De Bruijn cycle' and coding specialists call a 'Gray code' or 'bracelet code'. It has unique properties which are very useful for the mentalist.
