Echoes in Death, the 44th book in JD Robb’s prolific futuristic, science-fiction murder mystery series, opens with Lt. Eve Dallas and her husband, Roarke, discovering a naked and battered woman wandering the frozen New York City streets. After racing her to the hospital they learn that she is the young wife of a prominent surgeon. Once the hospital staff confirm her identity and concur that the young woman has been the victim of a brutal physical and sexual attack; Dallas and her partner, Peabody, arrive at her home to find her husband has been murdered, presumably by the same attacker as his wife.
On the surface the attacks appear to be a rape/murder perpetrated in the course of a home invasion. All evidence points to that conclusion: the home of a wealthy couple invaded, the couple attacked, and the attacker had left only after stealing artwork, cash, and jewelry. As the wife begins to regain her memories of the evening, and Dallas and Peabody interview friends of the couple, information that suggests that the husband abused his wife (and possibly a previous wife) comes to light and the cops have to work out whether she killed in self-defense or if someone else was involved in an elaborate escape plan.
Two fellow NYPD detectives approach Dallas and Peabody with evidence that links two of their cold cases with her murder investigation and all four detectives agree that the three cases are similar enough that the attacker most likely is a serial rapist who has escalated into murder.
Tracing the intricate relationships between the three cases, the team begin to uncover a pattern: the murderer is targeting prominent, wealthy couples in which the wife is extraordinarily beautiful. Dr. Mira, the department psychiatrist and recurrent character in the series, creates a chilling profile that suggests the killer is attacking “surrogates” who reminds him of someone he has long known and long wanted to harm.
Although this series can be formulaic and repetitive, this book felt reinvigorated and the plot and details kept it feeling fresh and fast paced. A dark series, too dark for those sensitive to graphic murder mysteries, but one that has fought to remain vital after forty+ books.
