Conjurors' Mechanical Secrets - 137 pages

Sharpe examines the fake, or secret property of the prop used, which accomplishes the deception.  He points to 11 basic ways that a fake can be accomplished.  He also examines what he calls the auxiliary aid which is not part of the actual prop but is hidden and makes the magic happen.In discussing these principles he covers the working of tricks and illusions such as:

Conjurors' Psychological Secrets - 178 Pages

This book examines the mind's contribution to illusion and perception.  One example that Sharpe points out in the book is the Disarming Time Lapse, where he explains that when a card is returned to the deck there is period time that the spectator is expecting some trickery, and the magician is wise to let this time pass prior to attempting any moves.  As magician's we are quick to buy the latest trick or DVD, but the student of magic is wise to study the psychological aspects of magic to make illusions that much more convincing or deceptive. 

Sharpe says in his introduction:

We are inherently incapable of accurately describing what we see, and must always fill in such details as will accord with the particular explanation which appeals to us most. In fact we see with our mind as much as with our eyes, since experience, memory, and belief add expectation to the picture presented to our physical vision.  In consequence, it would sometimes be true to say that"believing is seeing," especially at spirit seances.

Sharpe covers the following subjects:

• Objective Illusions
  • Visual Illusions
  • Auditory Illusions
  • Illusion of Touch, Taste, and Smell
• Subjective Illusions
  • Illusions of Mental Time
  • Illusions of State
• Influence by Suggestion
  • Creating Atmosphere
  • Influencing Choice - Forcing
  • Misdirection
