39914471.499 Cook, Robin VECTOR Doctor Cook, King of the Mind-bending Medical Thriller (from Coma to Invasion to Toxin), returns with a swoon-worthy killer-poison more dangerous than any before it.. A vector, as in the title, is a carrier that transmits an infectious agent from one host to another. Back from Chromosome 6 (1997) are Drs. Jack Stapleton and Laurie Montgomery, forensic pathologists in the New York Chief Medical Examiner’s office. The first victim to come under their scope is Jason Papparis, a rug dealer who inhaled a fatal dust sent to him in a small box—how grisly, how amusing, a rug dealer murdered by dust! Also on hand at the morgue is dead and mutilated young skinhead Brad Cassidy, victim of the People’s Aryan Army, which has been recruiting skinheads as shock troops and “tapping into that well of hatred and violence the music has engendered” (in Cookprose, music can engender a well). The pathologists find that Papparis died of anthrax. As it happens, a disaffected Russian, Yuri Davydov, once a low-level worker in a Russian bioweapons lab, has managed to get himself into the US and turn Manhattan cab driver. An anti-Semite, Yuri feels dismissed as a human being by American Zionists and has set up a bioweapons lab in his basement in Brighton Beach, undertaking what he calls Operation Revenge. Meanwhile, he falls in with ex-military noncoms Steve Henderson and Curt Rogers, who are now NYC firemen as well as followers of the People’s Aryan Army. The three hatch a plot to avenge Ruby Ridge by releasing Yuri’s anthrax into the ventilation system of the 40-story Jacob Javits building, while Yuri also really wants to stick it to Manhattan’s Jews by encircling Central Park with a ring of the incredibly infectious toxin. What can a mere pair of pathologists do to stop this crew of nuts? Cook himself believes that a bioterrorist event is, without question, locked into our future. Not really a thought to minimize, as his cautionary tale observes.
