Mallory's oracle - Carol O'Connell

When Kathleen Mallory was ten she was a street kid and a thief. Then a cop called Markowitz took her home to her wife to civalize her. . . . Now Mallory is in charge of a complex database and a police officer herself, and someone has just murdered the man she considers her father -the only man she has ever loved. More used to the company of computers than people, Mallory descends into the urban nightmare of New York, to hunt down a cold-blooded killer. MALLORY'S ORACLE is a dangerous chase through the city's underworld, down the fibre-optic cables of high-tech computer networks and behind the blinds of genteel Gramercy Park - and an investigation into the chilly heart of it's damaged and elusive heroine.
