In her sixth spellbinding adventure, Carlotta Carlyle, the 6'1" redheaded P.I. from Boston, takes on a case that draws her into the mysterious shadova and of computer technology, where information is cheap, and privacy may be a thing of the past. Part-time cabbie Carlotta is entering the modern age of investigation. With the help of her sometime lover, mafioso, and computer-hobbyist Sam Gianelli, she invests in her first "hardware," a cheap personal computer. And at the urging of her ex-boss, Boston Police Lt. Mooney, who decries the stopping power of her .38 S&W, she decides to upgrade her arsenal. Both types of hardware come in handy when Carlotta is hired by Gloria, owner of G&W Cab, to investigate the brutal robberies that are causing her cabbies to quit in record numbers, and the violence and unanswered questions escalate.
