CATFISH GURUIt should have been a quiet week lecturing at a biotech symposium in the northern Michigan resort town of Traverse City. But when Mac and his son meet Steve Ferrante during a walk on the beach, it triggers anything but a quiet week. Only an hour after hinting he might be interested in hiring Mac to analyze the toxicological data he has accumulated during his catfish research, Mac finds Ferrante dead, face down in Grand Traverse Bay.
