Book Review: Guilty by Definition by Susie Dent – an enthralling mystery for word lovers

How to head up a book’s chapters is a big decision for any fiction author. Do you give them enticing titles or apposite quotes, or just leave them numbered? Susie Dent begins each of the chapters in Guilty by Definition with an interesting word and a dictionary-style description. Some are really old, like “mathom, noun (Old English): a precious thing; a valuable gift”; others more recent, like the verb “broggle (seventeenth century): to poke with a pointed instrument”; and there’s one or two that are quite new, like “zugzwang, (twentieth century): the obligation to make a move, but every move is detrimental”.

The main characters in the novel are lexicographers, editors for the Clarendon English Dictionary, so words are their thing. Not just words and their meanings, but their history, their earliest known usage and how they have changed over time. This alone would have been quite interesting as the characters are all engaging, have secrets and things happening in their personal lives. The team of four are headed by Martha, whose sister Charlie was a PhD student who went missing a decade before. Martha had escaped to Germany for a decade and hasn’t been long home, slotting back into the house she grew up in with her widowed father.

She’d known there would be ghosts in Oxford. Martha wasn’t afraid of any headless horsemen, or nuns haunting the local ruins; it was Charlie, always Charlie she was afraid would find her. There had been times in the first year after her sister’s disappearance when Martha’s heart would stop as she spotted her through the crowd: the long blonde hair, the shapeless cardigan draped over a thin cotton dress. She’d hear a laugh, throaty and sudden, or catch a movement, a walk, a twist in the shoulders, and she’d be certain. Just for a moment. Then the illusion would shatter and the person she knew to be her sister would resolve into a stranger.

Also working at Clarendon we have Alex, a stylish older woman with a penchant for nice things; Safiya, a lively young woman who shares a flat with others her age; and Simon, who misses family life since his divorce. Their boss is Jonathan, a Shakespearean expert who is television’s go-to commentator for all things to do with the bard. He has good looks and charm in spades, perfect for the media.

They’re all just puddling along, lost in the rarified world of words, when a cryptic letter, penned by someone calling themselves Chorus, has them reaching for their pencils to decipher its clues. The letter starts them off on a quest to investigate Charlie’s disappearance, something Martha feels very sensitive about, as you might expect. Charlie was the golden girl of the family, and with Martha’s mother now dead, her father is still apparently grieving all this time later.

Then there are the postcards. This Chorus seems to be sending them not just to the core group at Clarendon, but other witnesses they visit to ask about Charlie. Seemingly quotations from Shakespeare, some of them verge on “poison pen”. There are more letters, and some wonderful scenes as Martha and co. delve into archives, visit old acquaintances, and uncover some disturbing facts about Charlie. We see Oxford in all its glory – old ruins and scholarly institutions, May Day celebrations, cafés and watering holes, leafy parks ideal for cycling. I was often googling as I read for images so I could imagine the settings all the better.

It all adds up to a wonderful read, erudite and witty, but not without its darker moments, as you’d expect of a good whodunit. Which this is. If you love cryptic crosswords, this will be a delight, but there’s still plenty to enjoy without trying to figure out the clues. I am thrilled to see that Martha will be back next year in another mystery in the series – Death Writ Large, out next March. Guilty by Definition is a four-and-a-half star read from me.
