About This Book
Forty years ago, Steven Smith found a children's book scrawled with mysterious annotations — the obsession of a teacher who vanished on a class field trip and was never explained. Now out of prison, Steven is determined to unravel what really happened: to the teacher, to the so-called Twyford Code hidden across a series of beloved novels, and to the gap in his own memory that refuses to fill. It's a cold case wrapped inside a cipher wrapped inside a man's uncertain past, and Hallett makes the not-knowing feel genuinely unsettling.
What distinguishes this book is its audacious structural conceit: the entire story unfolds through transcribed voice recordings, giving readers only what Steven chooses — or is able — to share. That unreliable, fragmented format isn't a gimmick; it's load-bearing. Hallett uses it to control tension with precision, letting silences and evasions do as much work as the words themselves. Readers who enjoy piecing together a narrative from incomplete evidence will find this format deeply satisfying, rewarding close attention in ways that a conventionally told mystery simply couldn't.
