STRUCTURE OF CONTENTS
The eight elements of the whole art of detection are represented as an octagon rather than simply as a list, in order to illustrate the fact that they are a system rather than a set. All elements are involved at all times. Each element is related to all other elements, as symbolized by the links between them. Thus INTUITION is the balance of OBSERVATION and DEDUCTION, EXPLANATION is not the fast act of detection but is simultaneous to all other elements, DOCUMENTATION is PREPARATION by creating your own personal history, DOCUMENTATION and COLLABORATION are ways of sub-contracting out some functions so that you are capable of INTUITION, and so on and on.
