The Grafton Group is a consortium of investigators, many of whom are specialists in a variety of investigative fields.
Investigators are professionals that provide a service which is based on experience. Like any other professional service provider; doctors, lawyers, accountants etc., you want the experience and skills of someone who has been in practice for some time, yet is constantly looking at, and evaluating, new methods and technologies as a professional. You are making a business decision when you retain any private investigator and you deserve a return on your investment.
