Hunting Season by P. T. Deutermann

Enjoyable story forgotten as quickly as it's read.  Would read another title by this author. Edwin Kreiss is a former FBI agent whose discovery of a Chinese espionage ring made him a lot of enemies and resulted in his early retirement. Now his daughter is missing, and nobody, least of all a junior G-woman named Janet Carter, is going to keep him from finding her. Browbeating the one clue to her disappearance out of a terrified college student, Kreiss follows his daughter's trail to a deactivated federal arsenal in southwestern Virginia, where a fanatic whose son was immolated at Waco is cooking up a plan to blow the ATF to bits.
