Murder One ‘It would have been criminal to miss it!’

‘I always love being part of Murder One – it has rapidly become an important fixture in the literary calendar for anyone connected to the  crime and thriller genre. I also enjoy the fact it takes place in a library – it is impossible NOT to quietly look for a body, a dagger and a rapidly disappearing Colonel Mustard’
SIMON TREWIN – Literary Agent

We were thrilled with the success this year of Murder One Fest 2023, which was brought to you with the invaluable support of DLR Libraries. Back in it’s weekend format, October 6th-8th, we welcomed a host of Irish and international authors. We were delighted to have the wonderful Bob Johnston of The Gutter Bookshop on hand supplying everyone with books from both new, and already favourite, authors. Also a big thank you to Paul Sherwood Photography for all the fantastic photos which really capture the spirit of the festival.

Crime is one of the biggest-selling genres in the book business and Ireland boasts some of the world’s top crime writers. The festival showcased the cream of Irish crime writing talent with Tana FrenchJane Casey, Colin Walsh, Catherine Ryan Howard, Steve Cavanagh, Andrea Mara, Sam Blake, and Catherine Kirwan among those appearing on a range of solo events and hot-topic panels.

UK visitors included the hugely popular, Sophie Hannah, 2023 Sunday Times Young Writer of the Year, Tom Benn, Alice Feeney, author of the phenomenally successful Daisy Darker, plus cosy crime specialist, British Book Awards winner Janice Hallett, and highly praised debutante, Alice Bell.

Once a name synonymous with breaking news of high-profile crime cases, Dr Marie Cassidy has turned her hand to crime fiction and she discussed her debut novel, Body of Truth, in conversation with bestselling crime writer, Liz Nugent. 

True crime fans were entertained by award-winning political journalist, Harry McGee whose book, The Murderer and the Taoiseach, retraces the extraordinary happenings in Dublin’s notorious Malcolm Macarthur murder case.

Wherever your tastes in the crime genre lie, we hope you were gripped by the plot of Murder One this year.

Murder One in the Library Event Details:

Deadly Women with Vaseem Khan

Monday 8th November 8pm      FREE but booking required

Both Adele Parks and Jane Casey have stepped into new worlds with gripping psychological thrillers – both with strong female leads. Vaseem Khan, the award winning creator of Inspector Persis Wadia, India’s first female detective, quizzes them on the what, where, and how, and why women make such compelling lead characters.

Adele Parks was born in North Yorkshire. Selling over 4 million books in the UK and translated into 31 languages, she is the author of twenty bestselling novels including the recent Sunday Times Number One hits Lies Lies Lies and Just My Luck. Both optioned for development for TV in conjunction with Netflix producers. She’s an ambassador for The National Literacy Trust and a judge for the Costa. Adele has lived in Botswana, Italy and London, and is now settled in Guildford, Surrey, with her husband, son and cat. Both of You is Adele’s 21st book in 21 years.

Crime is a family affair for Jane Casey. Married to a criminal barrister, she has a unique insight into the brutal underbelly of urban life, from the smell of a police cell to the darkest motives of a serial killer. This gritty realism has made her books international bestsellers and critical successes; while Detective Constable Maeve Kerrigan has quickly become one of the most popular characters in crime fiction.

Winner of the Mary Higgins Clark Award for The Stranger You Know, Jane has been shortlisted four times for the Irish Crime Novel of the Year Award and longlisted for the CWA Dagger in the Library Award. She is a top ten Sunday Times bestselling author. Her No 1 bestseller, standalone thriller The Killing Kind is out now.

Vaseem Khan is the author of two crime series set in India, the Baby Ganesh Agency series set in modern Mumbai, and the Malabar House historical crime novels set in 1950s Bombay. His first book, The Unexpected Inheritance of Inspector Chopra, was a Times bestseller, now translated into 15 languages. The second in the series won the Shamus Award in the US. In 2018, he was awarded the Eastern Eye Arts, Culture and Theatre Award for Literature. Vaseem was born in England, but spent a decade working in India. In 2021, Midnight at Malabar House won the Crime Writers Association Historical Dagger. His latest book is The Dying Day about the theft of one of the world’s great treasures, a 600-year-old copy of Dante’s The Divine Comedy, stored at Bombay’s Asiatic Society.

Murder in Mind: Val McDermid in conversation with Liz Nugent

 Monday 22nd November 8pm   FREE but booking required

Number one bestselling crime novelist, Val McDermid, discusses her new novel, 1979, with our own Liz Nugent in what is sure to be a sparky and marvellously engaging event.  In 1979 Val kicks off her first new series in nearly twenty years with the story of Allie Burns, a young investigative journalist whose work leads her into a world of corruption, terror, and murder.

It’s only January, and the year 1979 has already brought blizzards, strikes, power cuts, and political unrest. For Allie Burns, however, someone else’s bad news is the unmistakable sound of opportunity knocking, a chance to escape the “women’s stories” to which her editors have confined her. Striking up an alliance with budding investigative journalist Danny Sullivan, Allie begins covering international tax fraud and a group of Scottish ultranationalists aiming to cause mayhem ahead of a referendum on breaking away from the United Kingdom. Their stories quickly get attention and create enemies for the two young up-and-comers. Drawing on McDermid’s own experiences as a young journalist, 1979 is redolent of the thundering presses, hammering typewriters, and wreaths of smoke of the Clarion newsroom. A journey to the past with much to say about the present, it is the latest pitch-perfect, suspenseful addition to Val McDermid’s crime pantheon.

Val McDermid’s novels have been translated into forty languages, and have sold over seventeen million copies. A remarkably versatile writer, as well as novels, Val has written radio plays, short stories, non-fiction and even a children’s book and has won many awards internationally, including the CWA Gold Dagger for best crime novel of the year and the LA Times Book of the Year Award. She was inducted into the ITV3 Crime Thriller Awards Hall of Fame in 2009, was the recipient of the CWA Cartier Diamond Dagger in 2010 and received the Lambda Literary Foundation Pioneer Award in 2011. In 2016, Val received the Outstanding Contribution to Crime Fiction Award at the Theakston Old Peculier Crime Writing Festival and in 2017 received the DIVA Literary Prize for Crime.

Before becoming a full-time writer, Liz Nugent worked in Irish film, theatre and television. Her novels – Unravelling Oliver, Lying in Wait and Skin Deep and Our Little Cruelties have been Number One bestsellers in Ireland and she has won four Irish Book Awards (two for Skin Deep). She lives in Dublin with her husband.
