What to expect

This audiobook features an exclusive introduction from Susie Dent, and an exclusive Q&A between Susie and Youtube's Jack Edwards.

When an anonymous letter is delivered to the Clarendon English Dictionary, it is rapidly clear that this is not the usual lexicographical enquiry. Instead, the letter hints at secrets and lies linked to a particular year.

For Martha Thornhill, the new senior editor, the date can mean only one thing: the summer her brilliant older sister Charlie went missing.

After a decade abroad, Martha has returned home to the city whose ancient institutions have long defined her family. Have the ghosts she left behind her been waiting for her return?

When more letters arrive, and Martha and her team pull apart the complex clues within them, the mystery becomes ever more insistent and troubling. It seems Charlie had been keeping a powerful secret, and someone is trying to lead the lexicographers towards the truth. But other forces are no less desperate to keep it well and truly buried.

Excellent story - easy to absorb and be absorbed. Wonderful narration of different character voices. I enjoyed the feminist theme highlighting how women historically and present day, continue to be overlooked and underestimated. Have recommended to friends.

A very enjoyable read, especially for anyone interested in words. Fun and engaging with some emotional and intellectual content. A wee dose of literary apricity!

Crime mystery with real heart. This is a wonderful book, crammed - as you’d imagine - with fascinating insights into the stories behind words - but also a solid plot, well drawn relatable characters, and a proper mystery to solve. Looking forward to the promised sequel.

I really enjoyed this book, to the extent that I did a few extra laps round the building on my way to work in order not to stop just as a key point arrived.

On the whole, the characters are well written. Keep going at the end to hear the interview with the author where she describes how she tried to avoid taking them too far. The odd little irritations with them are actually what makes them more real.

The plot is good and moves along well. There are bits where I began to suspect things, which again, makes the interview at the end more interesting.

I enjoyed the "wordy" bits. The definitions and explanations worked well interspersed with the story. You couldn't really expect anything else in a book about dictionary editors.

There is discussion of a sequel, which I very much hope comes along soon. I'd like to hear more about some of the minor characters as well as the main players.

All in all, I would heartily recommend this to anyone who likes mysteries, words and Oxford.

Guilty by Definition by Susie Dent.

I was a little apprehensive about reading a celebrity written book because they often are not great or extremely formulaic. While the story might be good, the writing often leaves something to be desired. Also, I really like what I have seen of Susie Dent and I didn't want my opinion spoilt.
However, the book is delightful. The story was good but in addition, it was informative about how dictionaries are created and the etymology of words. I remember reading about the early days of the OED with the input from an inmate of Broadmoor and this gives a more contemporary take on it.
For all these reasons and more, I would recommend this book to anyone who likes a mystery especially if you are a word nerd.
