Janice Hallett Books in Order

Janice Hallett grew up in an outlying suburb of London, where, by her own account, pony books had to stand in for actual ponies. She started writing young, and at fourteen she joined the Raglan Players in Northolt, west London. That early love of amateur theatre would turn out to be useful later.

She studied English at UCL, graduating in 1990, and later took an MA in screenwriting at Royal Holloway. Before novels, her working life moved through magazine editing, award-winning trade journalism, and government communications. For years she wrote for beauty industry magazines, then produced articles and speeches for departments including the Cabinet Office, the Home Office, and the Department for International Development.

She came to crime fiction later than many writers do.

By then she had already built a solid career in other forms. She wrote plays, including NetherBard, and co-wrote the feature film Retreat. But she has said that the slow, uncertain business of getting screen projects made pushed her toward novels, where she could control the whole structure herself. Once she found the right format, the work clicked.

That format was the document-driven mystery. The Appeal, her debut, is built from emails, texts, letters, and case files, and it made an immediate impression. Set around a village theatre group, a fundraiser, and a murder, it won the CWA New Blood Dagger in 2022. Her second novel, The Twyford Code, turned voice-note transcripts into a code-breaking mystery and won the British Book Award for Crime and Thriller Book of the Year in 2023.

What readers tend to love about Hallett is not just the puzzle, though the puzzles are a big part of the fun. She is very good at groups under pressure. An amateur dramatics society, an art course, a pub quiz crowd, rival true-crime writers, siblings sorting through an attic box, she likes places where people talk too much, hide too much, and accidentally reveal themselves in the smallest messages.

Her books are brainy, but they are never cold.

In The Mysterious Case of the Alperton Angels, The Examiner, and The Killer Question, she keeps finding new ways to turn ordinary paperwork into suspense. WhatsApp chats, essays, police interviews, quiz sheets, and manuscript excerpts all become clues. Even when the setup sounds playful, the emotional stakes are real, and the tension usually comes from something very human: guilt, ambition, shame, class anxiety, or the need to be believed.

In 2025 she moved into children's fiction with A Box Full of Murders, bringing the same found-document energy to a younger audience. It feels like a natural step. She trusts readers to keep up, and she likes giving them enough information to solve things for themselves. Hallett lives in London and has written about how much travel matters to her, from Madagascar to the Galapagos and from Guatemala to Japan. That curiosity shows on the page. Her stories invite you to snoop, compare notes, and notice the detail everybody else missed.
