With so many different versions of the truth teller/liar plot coming out, it is hard to remember them all. Now imagine a system that allows you to do this and more with barely anything to remember because you will KNOW if they are lying or telling the truth! Without logic puzzles, predetermined questions or psychological forces, you will be able to accurately determine someones lies and their truths and track the whereabouts of objects, thoughts and… well, whatever you want really!

Imagine you display three coins of different denominations and one drinks bottle cap. You instruct a spectator to place the cap over one of the coins and then, with the other two coins, to place one in each hand. You instruct them to either lie to you or to tell you the truth and after a couple of questions and their best poker face, you reveal where each coin is and whether they were telling you lies or the truth!

The book is laid out with practise scenarios so that you can test yourself, which makes the learning of the system an absolute breeze!
