Jean-Marc Krogman was a Solarian citizen and a competent and well-respected psych adjuster.
He was killed by Henry Thoreau and his partner, who assumed his identity. The new Jean-Marc Krogman registered with Manticoran immigration and established himself in a small but comfortable, and low profile, practice as a licensed psych-adjuster. Krogman primarily worked for the local criminal underground with an occasional freelance job. Krogman and Thoreau were hired to assassinate Crown Princess Adrienne, however the attempt was thwarted by treecats and Thoreau was captured. (HHA2.2: WPD)
