About This Audiobook

When lexicographer Martha Thornhill returns to Oxford after a decade away, she expects to immerse herself quietly in the world of dictionary editing at the prestigious Clarendon English Dictionary. Instead, cryptic anonymous letters begin arriving at her office, each containing elaborate word puzzles and coded messages that seem to point toward a devastating family tragedy: the mysterious disappearance of her brilliant older sister Charlie years earlier. As Martha and her team of fellow word enthusiasts decode increasingly complex linguistic clues, they uncover layers of buried secrets that someone desperately wants exposed while others will kill to keep hidden.

The multi-narrator approach transforms this cerebral mystery into a richly textured audio experience. Louise Brealey delivers Martha's emotional journey with nuanced vulnerability, while Susie Dent's own participation adds authentic scholarly gravitas to the lexicographical elements that drive the plot. Jack Edwards rounds out the ensemble with compelling supporting voices that bring Oxford's academic atmosphere to vivid life. The format particularly enhances the puzzle-solving aspects, as listeners can follow along with the word games and etymological detective work that form the story's backbone, making each revelation feel earned and satisfying.
