About Fiona Red
Blake Pierce’s Fiona Red series builds its serial-killer investigations around forensic entomology, giving its central FBI agent access to evidence that most investigators barely notice. Fiona spends much of her professional life in laboratories and at crime scenes, examining the insects attracted to human remains. Their species, life cycles, and stages of development can help establish when a victim died, whether a body was moved, and which environment may have concealed it before discovery. For Fiona, a corpse is never silent; it has already become part of a living system capable of preserving the killer’s mistakes.
Her ease around death began long before she joined the FBI. Fiona grew up in a family that operated a funeral parlor and once expected to enter the business herself. That path ended after her sister was abducted during their teenage years and never found. The disappearance transformed Fiona’s familiarity with bodies into an obsession with uncovering what happened before death, particularly when conventional evidence has disappeared. Her career becomes both a use for her unusual abilities and a continuation of the search her family could never complete.
Let Her Go introduces Fiona as a brilliant but isolated forensic examiner who expects to remain behind the scenes while field agents pursue a new serial killer. When a victim is found in rural woodland covered with insects that do not fit the apparent crime scene, Fiona recognizes that the body’s condition is telling a different story from its location. Her insistence on following that discrepancy draws her out of the laboratory and into direct contact with an offender capable of anticipating the investigation.
That movement from specialist to active investigator shapes the larger sequence. Fiona is most comfortable when evidence obeys biological rules: insects develop according to temperature, decomposition follows recognizable stages, and environmental traces can be compared. Human behavior is less orderly. Killers manipulate scenes, alter conditions, choose victims for private reasons, and sometimes leave biological clues deliberately. Fiona must learn when her scientific conclusions are reliable and when an offender is using her expertise to guide her toward the wrong interpretation.
The cases repeatedly exploit unusual relationships between bodies and their surroundings. Victims may be found in forests, wetlands, abandoned structures, or carefully controlled environments where decomposition becomes part of the mystery. Rare insects, unexpected infestations, concealed remains, and misleading timelines allow Fiona to reconstruct events that occurred before the body was discovered. Her knowledge gives the investigations their distinctive mechanism without reducing them to technical exercises; every conclusion carries urgency because another victim may already have been selected.
Fiona’s unresolved family history provides the sequence with emotional continuity. Her sister’s abduction remains more than the tragedy that inspired her profession. It influences how she responds to missing women, how far she will exceed her assigned role, and why she struggles to abandon a case when evidence becomes thin. Her determination can produce insights unavailable to more detached investigators, but it can also make her vulnerable to manipulation and lead her into danger without adequate support.
Each novel presents a new central threat, yet publication order preserves Fiona’s movement from laboratory loner toward a more experienced field investigator. Her professional relationships, confidence, and understanding of her sister’s disappearance develop between cases, while earlier risks shape later decisions. Across thirteen installments, the series remains focused on a woman trained to read the smallest forms of life surrounding death—and driven by the one absence she has never been able to explain.
