Truly Devious: A Mystery Novel Set in a School

Truly Devious, by Stephanie Perkins, opens at Westminster College, an elite New England boarding school where scholarship student Audrey Rose is trying to balance classes, friendships and a very private ambition. She wants to be a detective. When clues connect the school to the Ellingham murders, her interest becomes personal, carrying her back into a case that also involves her long-missing father.

Perkins structures the novel through two timelines: Audrey’s present at Westminster and events from 1998. This dual narrative lets readers watch a teenager piece together a puzzle while comparing her deductions with those of the people who lived through the original events. The result is a campus mystery that treats routines, status and secrets as genuine sources of danger.

A mystery rooted in school life

Westminster is more than a decorative backdrop. Class schedules, dormitory corridors, common rooms, meals and student rituals shape both the atmosphere and the investigation. Familiar details invite close reading, since a misplaced note or an unusual absence can matter as much as a dramatic confession. The setting gives ordinary school life the tense, enclosed quality found in the best campus mysteries.

Australian readers will recognise prefects, house teams, uniforms and assemblies, even though residential boarding for an entire school year is less common here. Most Australian students attend a local day school and travel home after class, often by bus, train or parent pickup. That difference makes Westminster’s constant supervision and social hierarchy feel deliberately intense.

Two timelines sharpen the search

The alternating timelines provide momentum without requiring confusion. The 1998 material introduces the Ellingham family, the disappearance of evidence and a network of adult secrets; the present timeline follows Audrey as she tests her adult assumptions against what she can uncover. Each visit to the past adds context, while each return to school raises the pressure.

Perkins also understands that a satisfying mystery depends on trust. Readers need room to suspect sensible people, reinterpret harmless exchanges and notice the details Audrey initially overlooks. Her analytical mind is useful, but emotion repeatedly complicates it. Loyalty to friends, curiosity about her father and fear of being excluded can drive her towards mistakes.

Characters hide more than they show

Audrey is more than a clever label. She is ambitious, awkward, loyal and often too self-assured about patterns she can read. Her confidence makes her funny, yet her mistakes prevent her from becoming a remote puzzle-solver. The novel repeatedly reminds us that intelligence cannot replace empathy, especially when judging the motives of people who have grown up under pressure.

Her friends and classmates carry their own masks. Lana is socially astute and fiercely competitive, while David “Joker” Dawes uses hostility to protect a vulnerable position. Their behaviour can look suspicious because each has something to conceal. Perkins keeps moral complexity in view: a secret is not always evidence of guilt, and an irritating person is not automatically the villain.

Clues, puzzles and playful prose

The clues are woven into dialogue, schedules and small physical details rather than delivered as a single grand revelation. Perkins includes messages, library research and coded references that reward the sort of attention many readers give a crossword. A quick Australian “squiz” at the beginning of a chapter can reveal a contradiction, while a reread can expose a line that changed its meaning.

The tone moves easily between suspense and dry humour. Audrey’s inner commentary prevents the darker material from becoming relentlessly grim, and the students’ banter sounds like teenagers trying to sound more sophisticated than they feel. The puzzle remains readable for younger teens, while mature themes—murder, grief, bullying and family dysfunction—make it more suitable for older readers and adults.

A New England story for Australian readers

The American setting requires a little cultural adjustment, and that contrast adds interest for readers in Australia. American private-school traditions, especially an elite residential college, sit differently from the local system of government and non-government day schools. Prefect duties may be familiar, but the novel’s old-money reputation, inherited influence and secret societies feel rooted in a particular version of the United States.

Readers can still map the school rhythm onto familiar Australian routines: an “arvo” tea break, a canteen selling sausage rolls and ice creams, or younger students in polo shirts and tracksuit bottoms. In Melbourne, Sydney and regional centres, public libraries, school reading programmes and community lending schemes provide practical ways to bring the novel into a discussion group.

What makes the mystery worthwhile

The strongest appeal is the way the mystery grows out of relationships. A school is a place where reputation travels quickly, private resentments overlap with public rules and adults may know more than children realise. Perkins uses those pressures to produce suspense that feels rooted in lived experience rather than manufactured danger. Even a locked dormitory or a missed class can carry genuine tension.

It is a good choice for readers who want a puzzle with a distinct voice, and for families willing to discuss why characters make the choices they do. Sensitive readers should know that the story includes death, grief, bullying and manipulation. Taken as a whole, it is clever without becoming mechanical, emotionally engaging and unusually strong on the value of paying attention.
