Lassiter and Martinez

Barbara Lassiter and Susan Martinez, two New Mexico homicide detectives, are assigned to investigate the murder of a wealthy Albuquerque socialite. They soon discover that the victim, a narcissistic borderline personality, played a lifetime game of destroying people's lives. As a result, the list of suspects in her murder is extensive. The detectives find themselves enmeshed in a helix of possible perpetrators with opportunity, means, and motive.

In Dark Angel, the second in the Lassiter/Martinez Case Files series, Detectives Barbara Lassiter and Susan Martinez pick up where they left off in Borderline. Assigned to a murder case, they discover that their suspect is much more than a one-off killer. In fact, the murderer appears to be a vigilante hell-bent on taking revenge against career criminals who the criminal justice system has failed to punish.

Called in to investigate a mysterious death in a retirement center, Lassiter and Martinez find themselves entangled in a case that might very well involve multiple murders committed by a psychopathic killer. The deeper they get into their investigation, the more complex and dangerous the case becomes, threatening the lives of the detectives and their loved ones. Political and bureaucratic machinations within the detectives’ department and the involvement of organized crime only make their jobs more difficult.
