Janice Hallett has carved out a distinctive niche in contemporary crime fiction, and with The Killer Question, she demonstrates why she’s earned the moniker “the new queen of crime.” This is a novel that asks readers to do more than simply follow breadcrumbs—it demands they actively piece together a puzzle from fragments of emails, text messages, quiz sheets, and police transcripts. The result is a reading experience that feels less like passive consumption and more like collaborative investigation, mirroring the very quiz culture at its heart.
The premise is deceptively simple: Sue and Mal Eastwood run The Case is Altered, an isolated rural pub whose fortunes have been revived by their popular Monday night quiz. But when a body surfaces in the nearby river and a mysterious team called The Shadow Knights begins dominating the competition with suspiciously perfect scores, the cozy quiz atmosphere curdles into something far more sinister. Five years later, their nephew Dominic is piecing together what really happened, assembling documents for a Netflix documentary about events that left the pub abandoned and his family destroyed.
The Architecture of Deception
What distinguishes Hallett’s work from traditional crime fiction is her commitment to the epistolary form. There’s no omniscient narrator smoothing over gaps or providing convenient exposition. Instead, readers must navigate a maze of communications, each offering a limited perspective colored by its author’s biases, secrets, and blind spots. The format itself becomes a meditation on how we construct truth from competing narratives and incomplete information.
The novel opens with Dominic’s correspondence with a documentary producer, establishing a frame narrative that allows Hallett to organize her source material into thematic “episodes.” This structure proves ingenious, as it mirrors both the episodic nature of television true-crime documentaries and the round-by-round progression of a quiz night. Each section builds tension while introducing new complications, ensuring that just when readers think they’ve solved one mystery, another layer reveals itself.
The documents themselves are remarkably varied and authentic. Quiz answer sheets interrupt the flow of text messages between rival teams strategizing for victory. Police briefing notes from a past operation called Honeyguide gradually reveal connections to present-day events. WhatsApp group chats capture the petty dynamics and genuine camaraderie of regular pub quiz attendees. Hallett’s ear for different voices is impeccable—the clipped efficiency of police communications contrasts sharply with the verbose emails of eager quiz participants, while text exchanges between younger characters capture contemporary digital vernacular without feeling forced or dated.
The Community of Questioners
At the novel’s center is the rich ecosystem surrounding The Case is Altered’s quiz night. Hallett populates her story with a diverse cast of regulars: Let’s Get Quizzical, a team of elderly friends finding purpose in their weekly competition; The Sturdy Challengers, led by the obsessively competitive Chris who approaches quizzing with military precision; Ami’s Manic Carrots, young college students treating the quiz as social therapy; and the Spokespersons, a cycling club whose athletic discipline doesn’t translate to trivia dominance.
These characters could easily have been mere background noise, but Hallett gives each team distinctive personalities and interpersonal dynamics. The reader comes to understand why these people return week after week, even when they have no realistic chance of winning. The quiz night represents something beyond competition—it’s community, routine, and a refuge from the complexities of modern life. When that community is threatened, first by The Shadow Knights’ inexplicable winning streak and later by far darker revelations, the emotional stakes feel genuinely affecting.
The quiz questions themselves serve multiple narrative functions. On the surface level, they provide authentic texture, demonstrating Hallett’s own extensive knowledge of pub quiz culture. But they also function as thematic commentary, with rounds on deception, identity, and performance echoing the novel’s central concerns. Most cleverly, the questions become plot devices—information conveyed through quiz answers reveals character knowledge, creates suspicion, and ultimately provides crucial evidence.
Layers Upon Layers
Where The Killer Question truly excels is in its construction of nested mysteries, each revelation opening onto deeper questions. The initial puzzle—how are The Shadow Knights cheating?—seems straightforward enough. Quiz regular Chris becomes convinced they’re accessing answers through some technological means, and much of the early novel concerns his attempts to prove their deception.
But Hallett has far more ambitious plans than a simple cheating scandal. The arrival of The Shadow Knights coincides with the discovery of a body, and Sue and Mal’s nervous behavior suggests they’re hiding something significant. Documents from their past as police officers introduce Operation Honeyguide, a failed undercover operation with murky ethical boundaries. The pub’s name itself—The Case is Altered—becomes a meta-textual hint about shifting identities and transformed circumstances.
The novel requires patience and attention. Hallett refuses to hold readers’ hands, trusting them to make connections between documents separated by hundreds of pages. A seemingly throwaway detail in an early email often proves crucial to understanding a later revelation. This demands the same active engagement as solving a particularly devious quiz question—readers must hold multiple pieces of information in mind simultaneously, testing hypotheses and adjusting theories as new evidence emerges.
Performance and Identity
Central to The Killer Question is an exploration of performance, both theatrical and social. Multiple characters have acting backgrounds or training in deception, and the novel continuously interrogates the line between assuming a role and becoming that role. When does pretending transform into reality? Can someone shed an identity once it’s been fully inhabited? These questions resonate beyond the specific plot mechanics, touching on broader themes about authenticity and self-invention.
The quiz night itself becomes a stage where participants perform versions of themselves—the know-it-all, the team player, the gracious loser, the sore winner. Mal’s role as quizmaster carries judicial authority, his pronouncement that “the quizmaster’s decision is final, even if he is subsequently proven to be wrong” taking on darkly ironic undertones as the story progresses. The theatrical metaphor extends to the climactic quiz where landlords arrive in costume, transforming The Case is Altered into a courtroom where truth and deception face off in a battle of wits.
Hallett draws subtle parallels between the performative nature of quiz participation and more sinister forms of deception. Both require knowledge of rules, careful presentation, and the ability to convince others of your authenticity. The novel suggests that we’re all performing to some degree, and the question becomes not whether we perform but what moral lines we cross in our performances.
The Power of Pairs
A recurring theme throughout the novel is the unique strength generated by partnerships. As one character observes, two people working in concert achieve far more than the sum of their individual capabilities. This applies equally to the married couples running the various pubs in the Ye Olde Goat brewery network, the quiz teams combining their knowledge, and more sinister partnerships revealed as the story unfolds.
Hallett explores both the creative and destructive potential of these bonds. Partnerships can represent loyalty, shared purpose, and mutual support—but they can also enable obsession, reinforce dangerous impulses, and provide the courage to cross ethical lines that individuals might hesitate before. The novel is populated with pairs, and tracking how these partnerships function and sometimes fracture provides another layer of thematic richness.
Structure and Pacing
At over 400 pages, The Killer Question is Hallett’s longest work to date, and it requires commitment. The epistolary format means exposition arrives obliquely, through fragments that must be assembled into coherent narrative. Some readers may find the early chapters challenging as they orient themselves to the cast of characters and the novel’s unconventional presentation.
However, those who persevere will find that Hallett’s pacing is carefully calibrated. The middle section, where multiple mysteries converge and the stakes escalate dramatically, achieves genuine page-turning momentum despite the fragmented format. Information that seemed irrelevant early on suddenly becomes crucial, rewarding attentive readers while encouraging rereading to catch details that take on new significance.
The novel’s structure in “episodes” for Dominic’s documentary works beautifully, allowing Hallett to shift between time periods and introduce documentary framing devices like police statements and interview transcripts. This metafictional layer—we’re reading the raw materials that will be shaped into a documentary—adds another dimension to the text’s engagement with truth, narrative, and the construction of meaning from fragmentary evidence.
Minor Quibbles
Despite its considerable strengths, The Killer Question isn’t without flaws. The sheer number of characters, particularly among the quiz teams, can overwhelm in early chapters. While most develop into distinct personalities, a few remain underdeveloped, their perspectives included more for plot logistics than character depth. The novel occasionally includes documents that feel repetitive, covering ground already established elsewhere.
Some readers may find the resolution of certain plot threads slightly convenient, with reveals that depend on characters behaving in specific ways to enable Dominic’s documentary investigation. The framing device of Dominic piecing together evidence sometimes feels like a mechanism to justify the inclusion of particular documents rather than organic storytelling necessity.
Additionally, the book’s length means that momentum occasionally flags in the middle sections. While the payoff justifies the setup, there are stretches where the accumulation of detail can feel exhausting rather than illuminating. Hallett’s commitment to showing rather than telling serves the novel’s themes but occasionally tests reader patience.
A Distinctive Voice in Crime Fiction
Janice Hallett’s previous novels—The Appeal, The Twyford Code, The Mysterious Case of the Alperton Angels, A Box Full of Murders and The Examiner—established her as a master of the epistolary mystery, each finding new ways to exploit the format’s possibilities. The Killer Question represents her most ambitious and fully realized work to date, demonstrating complete confidence in her chosen form while tackling her most complex plot structure.
What makes Hallett’s work so compelling is her refusal to use the epistolary format as mere gimmick. The fragmented presentation isn’t window dressing for a conventional mystery—it’s integral to the novel’s exploration of how we construct truth from competing narratives. In an era of fake news, deepfakes, and information warfare, a novel about the difficulty of establishing objective truth feels remarkably timely.
The quiz setting proves ideal for Hallett’s themes. Quiz culture is fundamentally about knowledge—who possesses it, how it’s deployed, whether it provides advantage or merely creates the illusion of advantage. The novel asks whether knowledge equals truth, whether being right matters more than being believed, and what happens when the questions themselves become weapons. These are concerns that extend far beyond the walls of The Case is Altered.
Final Verdict: A Brilliant, Layered Mystery That Rewards Active Reading
The Killer Question is Janice Hallett at her absolute best—ambitious, clever, and deeply engaged with questions about truth, identity, and the stories we tell ourselves. The epistolary format, which might have felt gimmicky in less capable hands, becomes a vehicle for exploring how narrative itself shapes our understanding of reality. The quiz setting provides both atmospheric charm and thematic resonance, while the nested mysteries ensure that even experienced mystery readers will find themselves surprised.
This is not a book to read passively. It demands attention, rewards rereading, and trusts readers to make connections without authorial handholding. For those willing to engage actively with its puzzles—both the explicit mysteries of plot and the implicit questions about knowledge and performance—The Killer Question offers one of the most satisfying reading experiences in recent crime fiction.
Hallett has created a novel that honors the intelligence of its readers while delivering genuine emotional stakes and a plot that justifies every one of its pages. It’s a book about community, knowledge, and the stories we construct from fragments of truth. Most of all, it’s a testament to the enduring appeal of a good question—and the dangerous power of knowing the answer.
