Abstract
An examination of the nature of investigative work describes the range of activities conducted by private investigators, the personal qualities needed by a professional investigator, and basic components of an investigation. An analysis of information lists both potential sources of information and methods of obtaining information. The use of contacts and informants, government and private sector sources of printed information, published sources of information, and methods of obtaining and filing information are described. Guidelines on observation focus on the uses of the senses, psychological aspects of observation, the factors which affect perception and memory, identification of specific head features and facial characteristics, and body features and characteristics. An explanation of report writing focuses on the identification of the purpose of the report, preparation for writing the report, the format to use, the processes of writing and editing, and the need for practice. Illustrations, chapter notes, an index, and 40 references are provided.
