Diana, prop-maker and zombie, steps back onto a television set with a corpse on the schedule and a Francine Leon dollhouse appearing where it has no business being. That opening is quintessential Courtney Smyth: cozy surface, genuinely unsettling undercurrent, and a puzzle whose pieces refuse to fit in the expected configurations. The Undead Complex audiobook, the second installment in Smyth's Undetectables series narrated by Matthew Lloyd Davies, picks up five months after the events of the first book, with the magical forensic investigation team navigating the uncomfortable gap between having saved their world and not knowing what to do next. Davies handles the full 13-hour-and-41-minute runtime across an ensemble that includes Diana, Mallory, Cornelia, and the steadily deteriorating Theodore, and his facility with the series' tonal range, from comic banter to genuinely dark character work, is one of the recording's most consistent strengths.
This is a book that will work considerably better for listeners who have already spent time with the Undetectables. One reviewer made that point directly: even having read the first book, the sequel's refusal to recap previous events can create temporary disorientation. Smyth clearly trusts her audience's memory, which is a compliment to her readers but a practical note for anyone considering a cold start.
Smyth's particular achievement in the Undetectables series is the way she integrates her LGBTQ+ ensemble into a genre story without turning representation into the plot's primary project. Diana, Mallory, and Cornelia are queer characters in a world with its own magical politics, and the story trusts that their identities are present and meaningful without requiring external validation or conflict to make them visible. The relationships between the three investigators carry a texture of genuine friendship, the kind built on history and friction and humor, and The Undead Complex deepens those dynamics rather than simply restating them.
The mystery construction is the series' most ambitious element. Each new clue in the TV-set murder investigation seems to contradict the previous one, and Smyth is deliberate about creating a puzzle that resists easy solution. The bodies accumulate in ways that violate the expected logic of the genre, which is both the book's structural hook and its most challenging element for listeners who prefer their mysteries to resolve cleanly. The Francine Leon dollhouse thread runs parallel to the main investigation with a patience that suggests Smyth is building toward something that extends beyond this volume. Davies handles these overlapping plot threads with clarity; a less organized narrative performance would allow the parallel storylines to blur into each other, but he keeps the distinctions audible.
Why Listen to The Undead Complex
Matthew Lloyd Davies brings genuine wit to the narration. Smyth's prose has a dry humor that requires a narrator who can deliver punchlines without announcing them, and Davies manages this with consistency. The comic timing in the Undetectables' banter is preserved rather than flattened, which matters because the series' emotional stakes depend on the audience caring about these characters as a group. If the humor fails to land, the darker developments, particularly Theodore's deterioration, lose their counterweight.
The TV-show setting is also a productive creative choice. The Undead Complex, the fictional program the Undetectables investigate, gives Smyth room to explore celebrity, creative industry dynamics, and the peculiar logic of production environments. Diana's history as a prop-maker means her perspective on the set is both professional and nostalgic, and that dual lens provides scenes with an emotional dimension the mystery plotting alone would not generate. Listeners who enjoyed the first book's world-building will find Smyth has extended the Undetectables' environment rather than simply replicated it. The in-world logic of Smyth's magical forensic investigation concept is developed further here than in the first volume; the Undetectables have accumulated enough case history that their methodologies feel established rather than improvised, and the second book benefits from that institutional depth.
What to Watch For in The Undead Complex
Theodore's arc in this volume is the emotional core beneath the mystery surface. His literal deterioration carries a weight that the comic tone of earlier scenes does not entirely conceal, and Smyth is careful about what it means for Mallory to watch someone she cares about come apart in ways she cannot fix. The secrets he is keeping from her are not simple plot mechanics; they reflect a character dealing with something he cannot make legible to the people who matter most to him. That dynamic is handled with more nuance than the mystery-comedy frame might suggest.
The final act moves quickly and introduces complications that are clearly designed to carry consequences into the next book. Readers who found the first volume's conclusion satisfying should expect a somewhat more open-ended resolution here. Smyth is building a series with genuine serial continuity, and The Undead Complex functions as a strong middle chapter rather than a self-contained narrative. One reviewer described the wait for the next book as requiring Diana-level patience, which captures the experience accurately.
Who Should Listen to The Undead Complex
Readers who completed The Undetectables and found the ensemble compelling will get the most from this audiobook. Fans of cozy-adjacent mystery with genuine bite, LGBTQ+ representation that is woven into character rather than announced, and ensemble dynamics with real interpersonal texture will find Smyth's series among the more distinctive offerings in the genre. Those who need their mysteries fully resolved before the final chapter should approach with mild caution. Matthew Lloyd Davies's narration makes the audio format a strong choice for the series, and at 13-plus hours, the runtime gives the world genuine room to develop. Listeners who follow Smyth's work will find that the series has a distinctive tonal signature that the audio format preserves well, and Davies's consistent handling of the ensemble makes the long runtime feel earned rather than indulgent.
- Narration: Matthew Lloyd Davies handles Smyth's dry wit with precision, preserving the ensemble's banter while giving the darker Theodore thread the weight it requires.
- Themes: Queer chosen family, grief and deterioration, identity and secrecy
- Mood: Witty and unsettling in equal measure
- Verdict: A strong second installment for the Undetectables, deeper and stranger than the first, built for an audience already committed to the series.
How does this audiobook handle its LGBTQ+ ensemble?
Smyth integrates the queerness of her characters into who they are rather than making it the plot's primary subject. The representation is present and substantive without requiring external conflict to validate it. The relationships feel like genuine friendships built over time.
Is The Undead Complex audiobook a complete story or does it end on a cliffhanger?
The central mystery receives a resolution, but several threads, including the Francine Leon dollhouse subplot and the consequences of Theodore's arc, are clearly designed to continue. The book reads as a strong series installment rather than a fully self-contained narrative.
How long is this audiobook and is it a commitment worth making for fans of the first book?
The audiobook runs 13 hours and 41 minutes. For listeners already engaged with the Undetectables, that length gives the world and the ensemble room to develop in ways a shorter production could not accommodate. For new listeners, the first book is the better starting point.
