Fox was a Grayson citizen and an officer of the Protectorate Security Detachment.

In 1903 PD, he held the rank of Captain and was assigned to Palace Security; he had been assigned to this post since Protector Benjamin IX had been a child.

Fox met Captain Honor Harrington of the Royal Manticoran Navy when she came over to the Palace for a meal with the Protector and his family. He was a little unnerved about her stature, and about the fact that she brought along her treecat, Nimitz, whom he perceived as a mere pet. He was killed in the line of duty when the Brotherhood of Maccabeus tried to assassinate Benjamin IX. (HH2)
