PRESENTING TWO DR. THEO MACGREGGOR MYSTERIES! NAME YOUR POISON Dr. Theo MacGreggor is the director of the Genetic Toxicology Lab at Green Earth Industries, Inc. When someone plants poison in his laboratory's coffee pot, Mac sets out to solve the murder. An expert on poisons, Mac is an ideal candidate to assist the police and the M.E.'s Office in their pursuit of the killer. As Mac walks the tightrope between corporate politics and a murder investigation, he realizes that one slip could cost him his job...or his life. CATFISH GURU It 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. In a case twisted by buried desires, secret lives and blackmail, Mac may be the only one with the key to unlock its mystery.
