The Gray Man

The Gray Man is a high-ranking member of a top-secret government agency known as the Network, often serving as Frank and Joe Hardy's contact in the agency.

The Gray Man is hard to predict, rarely showing his emotions, often coming across rather cold and uncaring. However, he has proven himself to be unselfish and brave, and has shown a softer side, willing to help people endangered because of their connection to the Network, and giving people respect when they deserve it.

The Gray Man has demonstrated in various books that he is very good at hand-to-hand combat, easily flooring both of the Hardy Boys several times. He is a shrewd, tough, and highly intelligent agent who is good at his job. He is also shown to be an extremely good shot, and carries a 9mm Beretta pistol in a shoulder holster under his suit.

He can blend in with virtually any crowd, and is as a short, balding man with little gray hair, gray eyes, and even a gray tint to his skin. He has been known to wear glasses, and has smoked cigarettes.
