It's a good book, but a lot of theory, not a lot of presentation stuff. I own the book, but haven't got round to reading it yet. From what I can gather, it's split into sections. Something like 'Vanishes', 'Productions', 'Transpositions' etc, with each section broken down into theories as to how the effect is achieved, for example, 'Productions' is split into 'the item was already there, but concealed', 'the original item was not there, but brought into play during some misdirection' etc.
Basically it's how magic is done, but not explaining the sleights or apparatus involved.
I think I've explained that OK.
