Grey’s Investigators have received the name ‘The Grey Men’ through years of excellent surveillance work. This of course being provided by the most skilled operatives in the united kingdom. Given this name by investigation companies throughout England our agents have become extremely well known. This is due to their training from the best training platforms and the fact they have been hand selected. Each of our investigators are certainly trained to blend into EVERY environment, notably along with being undetected whatever their surroundings!
