About Infernal Affairs
The Infernal Affairs series by Sherrilyn Kenyon blends urban fantasy, supernatural crime fiction, dark humour, and mythological intrigue into a world where the forces of Heaven and Hell operate alongside modern law enforcement. Centred on the exiled son of Lucifer and a detective with secrets of her own, the novels explore demonic conspiracies, supernatural criminal investigations, and the dangerous politics of the underworld. Set primarily in Savannah, Georgia, the series introduces a distinctly unconventional investigative partnership with the fate of humanity frequently hanging in the balance.
Lucian “Luke” Tievel is no ordinary investigator. As the son of Lucifer and a hellhound, he was once the favoured heir to Hell’s throne, enjoying considerable power and privilege within the infernal hierarchy. His position collapses when he is unexpectedly banished from Hell without an explanation. Stranded among humans, Luke becomes determined to discover who betrayed him, reclaim his former status, and punish those responsible for his exile.
Surviving in the mortal world, however, requires an occupation. Luke finds himself working for Infernal Affairs, a secretive law enforcement division responsible for investigating supernatural crimes and dealing with dangerous beings who threaten humanity. Its responsibilities extend beyond conventional policing, including determining whether supernatural offenders belong in ordinary custody or should be returned to the underworld.
His new partner is Detective Sorcha O’Malley, an experienced investigator whose determination and suspicious nature make her particularly resistant to Luke’s arrogance and demonic impulses. Assigned to keep him under control, Sorcha quickly discovers that working alongside Lucifer’s son presents challenges far beyond those of an ordinary police partnership.
Yet Sorcha is hardly an uncomplicated representative of humanity. Her background contains secrets she prefers to conceal, and her unexpected familiarity with demonic beings raises troubling questions about her own identity. Their partnership consequently develops around mutual suspicion, competing priorities, and a growing recognition that neither fully understands the other’s history.
The opening novel, Hell to Pay (2026), establishes this relationship through a disturbing investigation involving the deaths of college students in Savannah. Evidence increasingly points toward Luke as the perpetrator, suggesting that someone is deliberately manipulating events to implicate him. Already desperate to identify whoever engineered his exile, Luke must now confront an adversary whose knowledge of his circumstances makes the threat intensely personal.
The investigation places Sorcha in a difficult position. Her professional responsibilities require her to confront the evidence against her partner, while their shared experiences reveal the possibility of a conspiracy extending beyond the immediate crimes. The resulting tension combines elements of a supernatural detective mystery with Luke’s larger struggle against enemies connected to his infernal heritage.
Hell’s Half Acre (2026) expands the conflict from individual criminal investigations into a confrontation involving competing supernatural factions. As ancient powers begin manoeuvring for control, both Luke and Sorcha become targets. Forces associated with Heaven and Hell threaten the mortal world, creating a situation in which Luke must reconsider his ambitions and decide whether reclaiming his inheritance matters more than protecting humanity.
This development gives the series an important underlying contradiction. Luke initially regards Earth as an unwanted place of exile, yet his experiences increasingly challenge his attitude toward the imperfect human world. His resistance to being manipulated by powerful supernatural factions becomes inseparable from his determination to preserve his independence.
A third instalment, Hell Hath No Fury, is scheduled for 2027, continuing Luke and Sorcha’s investigations with another supernatural case.
Kenyon’s approach draws upon characteristics familiar from her paranormal fiction, particularly protagonists carrying painful histories, powerful beings governed by complicated hierarchies, and conflicts involving personal freedom. Infernal Affairs, however, places greater emphasis on investigative procedure and the uneasy working relationship between two recurring central characters.
Rather than treating supernatural creatures solely as romantic or mythological figures, the series places them within a functioning system of law enforcement, punishment, and competing jurisdictions. This provides opportunities for both dangerous confrontations and irreverent humour, especially through Luke’s irrepressible personality and Sorcha’s determination to maintain professional control.
Beneath the demonic conspiracies and supernatural investigations, Infernal Affairs examines loyalty, identity, betrayal, and the question of whether a person’s origins must determine their choices. Luke may be Hell’s intended heir, but his greatest challenge lies in deciding what kind of person he wishes to become when the powers that shaped his existence no longer control his future.
