Environmentalism meets Indiana Jones in these rip-snorting tales of a former wildlife conservation officer. The bad guys here are illegal deer hunters, law-breaking drag-boat fishermen who pilfer the ocean depths, poachers who kill elk, anglers who disrupt historic salmon spawning grounds and other miscreants who feed the flourishing illicit wildlife trade. Grosz has seen them all -- and arrested many -- in his 32 years as a special agent for the U.S. Fish and Wildlife Service and as a California state fish and game warden. A bear of a man -- six-foot-four, over 300 pounds -- Grosz relates his exploits in adventures full of slam-bang action and bravado tempered by a coolheaded sense of humor. Motivated by reverence for God's creation, he comes off as a mixture of guts and heart. In one episode, he sleeps overnight in a California rice field with a feeding flock of several thousand mallard ducks to protect them from commercial hunters. Full of gumption and guile, Grosz readily admits to failings that render him more likably human. He gets seasick and retches while making on-board boat inspections, and in one bust gone bad, a duck hunter sprays his backside with 189 shotgun pellets. Overall, these offbeat tales effectively dramatize the underfunded, underappreciated, dangerous and heroic activities of wildlife agents. (Oct.)
