Joseph Anthony Travers is a graduate of the Los Angeles County Sheriff’s Department Academy and a former Hawthorne Police Department (California) police officer.  Joseph Travers is the author of Introduction to Private Investigation.


According to the description of Introduction to Private Investigation it “is designed to provide the essential knowledge and procedures needed to operate successfully as a private investigator. It is both an instructional textbook for those individuals desiring a career as a private investigator, and a resource manual that can be an invaluable tool for later reference. The approach is a direct, concise style, which facilitates comprehension by novices as well as experienced private investigators, and makes possible competent and professional performance of all types of private investigation.


The purpose for writing this book is to fill the existing need within the field for a precise comprehensive text detailing the development of skills necessary for professional investigative work. In addition, there is a lack of recent, up-to-date textbooks currently available to individuals wishing to learn about private investigation. Introduction to Private Investigation will help fill this void. This easy-to-read textbook for investigators is filled with practical information and stories that will provide extremely valuable training.


One unique attribute of the book is its commitment to the practice of private investigation in the private business sector as well as the public sector. Another notable quality is its concern with both the portrayal of private investigation as a legitimate professional discipline and the subsequent degradation of the popular, media propagated misconceptions of private investigators. Two new chapters have been added in this second edition, “Criminal Defense Investigation” and “Bioethics, Investigation, and the Occult,” due to a complete lack of material for each subject pertaining to Professional Investigation. It will enable the professional investigator or apprentice to sharpen the skills they use every day.


Be it undercover, surveillance, interviewing, case preparation, or courtroom testimony, even the most seasoned veterans understand the need to be on top of their game in order to provide clients with the best possible results. This book will help you accomplish that understanding. It will provide you with the basic skills, knowledge and required tools before you go into battle with the Scales of Justice. Because the truth never changes. It is “the same, yesterday, today and forever.”
