Robin Cook's latest plot--the threat of an anthrax [bacterium] turned loose in a New York government building and in Central Park--is ripped straight from the headlines, and as such it may be charitably described as having a certain lumpish quality in the prose and an overabundance of cuteness in the lead characters. Jack Stapleton and Laurie Montgomery, the dueling forensic pathologists who bounced off each other in Cook's Chromosome 6, collide and combine once again as a mad Russian cabdriver, who used to work in a Moscow bioweapons factory, comes up with a plan to punish America for not welcoming him with open arms. The cabby forms an unlikely alliance with two firemen who happen to be white supremacists; they fund his anthrax research to further their own lunatic schemes. Cook is, as ever, best at creating scenes of perfectly realized medical terror which plug into the paranoia of the moment. But if you want deep characters and sensitive description, read Fay Weldon. --Dick Adler
