The investigation of a series of murders of wealthy, elderly women from the Gramercy Park area intensifies when Louis Markowitz, the head of the NYPD Special Crimes Section, is found dead with the third victim. Kathleen Mallory, his adopted daughter and a policewoman assigned to office duty, is beautiful, intelligent, fiercely independent, and obsessed with finding the killer. Mallory's computer skills supplement the street-survival savvy she learned before her adoption and the "wall" of clues and case details left by Markowitz. All of this leads her to seances, magic acts, dysfunctional families, insider trading, and, eventually, the knowledge her father had at his death. Mallory is the major, but not the only, complex and successfully realized character to emerge in this skillfull debut, which has the international publishing world's attention.
