How to develop mental magic by Paul Hadley is a two person code system, a hard cover book including a large learning chart. Without a doubt this books value in terms of knowledge is worth more then the price of the book itself. Although the code can use a facelift it is still possible to perform today.

I really loved the way this book teaches the code and helps you memorize it. The format is that of a text book where on one page there will be a list of objects and you must fill in blank spaces with the appropriate code and on another page a list of codes where you must fill in the name of the coded object. In my opinion this is a powerful method of learning and will help you memorize the code inside out. Even if you do not use this code the method of learning is worth applying to your code work.

This system is for the serious student and will require a lot of practice. The information in this book about practice, staging and performing are worth the books weight in gold. If you are a serious student of 2 person telepathy then this book is a must have.

I gave this book 4 stars out of 5. Even though I said that it is a must have for a serious student of coding because the code will need to be improved to fit modern speech but it is not a difficult task. The presentational tips, staging, and method of teaching are very powerful and will be useful to any student of 2 person telepathy.
