In Blacklight Blue, Peter May delivers a compelling continuation of his Enzo Files series, blending forensic science, historical intrigue, and emotional depth into a tightly woven crime narrative. The novel revisits Enzo Macleod, a half-Scottish, half-Italian forensic expert who specialises in solving long-cold cases—often where others have long given up. This instalment stands out not only for its intricate mystery but also for the personal stakes that run beneath the surface.
The story centres on a decades-old disappearance: a young woman who vanished without a trace in France. Her body was never found, and the case went cold—until Enzo took it on. What makes this investigation particularly fascinating is the unconventional method he employs. Using ultraviolet light (the titular “blacklight”), Enzo uncovers hidden evidence that had previously gone unnoticed. This scientific angle is one of May’s strengths, and he handles it with clarity and authenticity, making complex forensic techniques accessible without slowing the pace.
As Enzo delves deeper, the case evolves into something far more sinister than a simple missing persons mystery. The narrative skillfully shifts between past and present, revealing secrets layer by layer. May’s pacing is deliberate but never dull; each revelation feels earned, and the tension builds steadily toward a satisfying climax.
Characterisation is another highlight. Enzo Macleod is not your typical detective—he is intellectual, occasionally abrasive, and driven by a mix of curiosity and personal demons. His relationships, particularly with his daughters and romantic interests, add emotional texture to the story. These elements prevent the novel from becoming overly procedural and instead ground it in human experience. Readers who appreciate character-driven crime fiction will find much to engage with here.
The setting, primarily in rural France, is vividly rendered. May has a gift for evoking atmosphere, and the landscapes—vineyards, quiet villages, and historic sites—become almost characters in their own right. This sense of place enhances the mystery, creating a contrast between the beauty of the surroundings and the darkness of the crime.
One of the novel’s strengths lies in its intellectual puzzle. May doesn’t rely on cheap twists or sensationalism. Instead, he constructs a mystery that invites the reader to think alongside Enzo. The clues are there, subtly placed, rewarding attentive reading. However, some readers may find the pacing in the middle sections slightly slow, as the investigative process takes precedence over action. That said, this is a minor drawback in an otherwise engaging narrative.
Another notable aspect is the thematic depth. Beyond the crime itself, Blacklight Blue explores memory, loss, and the passage of time. It raises questions about how well we truly know the people around us and how secrets can linger long after they are buried.
Overall, Blacklight Blue is a strong entry in the Enzo Files series and a testament to Peter May’s skill as a storyteller. It combines intelligent plotting, rich character development, and a unique forensic angle to create a memorable reading experience. Fans of crime fiction will find this novel both satisfying, thought-provoking and entertaining.
