So many creators before me have contributed their thoughts on this idea; now it is my turn to add something to the mix.
Sherlocked is a system that can be used by itself, or in conjunction with other PIN code revelations. While it may take some study initially, once learned, it is easy to recollect and you can use it in virtually any environment - stage, close up, parlor, etc. - regardless of region or language barriers.
It is meant to be a foundation upon which you can build your own glorious performance variations, as many performers and creators already have.
With absolutely no forces, peeks, or awkward unexplained processes, this system will assist you in revealing a participant's freely thought-of PIN code.
You will also learn a variety of old school principles that you can use in many other areas of mentalism which will ultimately aid you in simplifying your methods so that you can work on your presentation.
