I did not think this book was very good. It is mostly how to use a confederate to help you do card tricks. There are too many ways to divine what playing card someone is thinking of to resort to using a confederate. I was really hoping for some secret coding systems that could be used for much more interesting things. But Angelo Stagnaro seems obsessed with card tricks. There was some good stuff in there, but overall it was a disappointment. It does at least provide some food for thought if you're not very familiar with partner codes.
