Stephen Fry and I are thrilled to be working with Mari on bringing the extraordinary Kate Daniels to life - Gina Carter.

Mari Christmas!

As the year draws to a close, I’d like to say a big thank you to everyone who’s visited here, followed me on Twitter or written to me. If you’ve borrowed or bought my books in 2016 – discovered DCI Kate Daniels or met DS Matthew Ryan – I hope you’ve enjoyed reading my work as much as I've loved writing it.

Have fun over the festive season and all the best for 2017.

I have news!

Thrilled to be able to share that I'm taking over as Reader in Residence at the Theakstons Old Peculier Crime Writing Festival. This means that I'll be taking the Big Read on the road to libraries across the north of England. I'll be celebrating the work of a much loved writer, PD James. The title chosen this year is a cracker: An Unsuitable Job For A Woman. For a full list of venues and dates visit my events page.


Coming later this year . . .

For those who’ve waited patiently for news of Kate Daniels 6, I can now share the cover of Gallows Drop and a little hint of what's to come . . .

At dawn on a lonely stretch of road, a body is found hanging from an ancient gallows the morning after a country show. Hours earlier, DCI Kate Daniels had seen the victim alive. With her leave period imminent, she's forced to step aside when DCI James Atkins is called in to investigate. There's bad blood between them. 

When Kate discovers that Atkins' daughter was an eyewitness to a fight involving the victim, the two detectives lock horns and he's bumped off the case. It's the trigger for a vicious attack on Kate, exposing a secret she's kept hidden for years and unearthing an even darker one. 

Shaken but undeterred, Kate sets out to solve a case that has shocked a close-knit village community. As suspects emerge, she uncovers a curious historical connection with a hangman, a culture of systematic bullying, a web of deceit and a deep-seated psychosis, any one of which could be motive for murder.

The novel will be published on November 17th 2016 and is available for pre-order by clicking the cover image.


Happy holidays.

Before the mania begins - whether or not you celebrate Christmas - I'd like to welcome new visitors from home and abroad and take a moment to thank the many librarians, bloggers, booksellers and readers who have contacted me in 2015. You are truly generous. 

I haven't written a poem, short or long story, self-published a special ebook for Christmas or named my favourite books of the year - there simply hasn't been time. I have enjoyed receiving your emails, laughed out loud and ocassionally shed a tear reading your wonderful posts on social media. 

If I have not kept up with your news, it is not for the want of trying. My year has had its ups and downs, but it has been an amazing one professionally and there is more good news to come in the New Year. Many thanks if you have read and reviewed my books. Your support means everything. Mari x


What the press are saying about The Silent Room 

A vivid new hero in this satisfyingly dark and tense thriller. The Independent

Voted by the Queen of Icelandic Crime Yrsa Sigurdardottir as one of her Best Books of 2015 for the Sunday Times Crime Club. Compelling characters, a gripping plot, superb pacing and heart, something many books in the genre sorely lack. 

Taut storytelling and razor-sharp dialogue. The Mail

Named as one of Marie Claire's Best Thrillers of 2015: Read it on your commute and you'll be looking over your shoulder the whole way home.

High drama and thrills kept credible by well-drawn characters. Sunday Times Crime Club

Pacey stand-alone thriller . . . delicious twists and turns. S Magazine

A hard-as-nails standalone thriller. Peterborough Telegraph

The Sun: A rollercoaster ride involving corruption, surveillance and espionage as Ryan uncovers an international conspiracy of the highest order. 

Masterful plotting and superb characterisation. Could The Silent Room herald the start of a very special new crime series? Lancashire Evening Post.

I'd like to thank all of the above and the many crime bloggers who have reviewed the book.



Whatever you say to a publisher is confidential, right?

My confession is on the Pan Macmillan site. This is a fun post ahead of publication next week of THE SILENT ROOM. I hope you enjoy.

PS: No animals were hurt in the process of this Q&A.

Some friendships just work.

A symbiotic relationship, a formidable team. That's the way I described my relationship with independent bookseller Helen Stanton ahead of IBW 2015. Head over to Indie Bound to read more.



Hot news! Just in: the cover image for my new standalone THE SILENT ROOM. Thanks to Justine Anweiler - Pan Macmillan art department - who has done an amazing job. I think it looks stunning.

THE SILENT ROOM will be published in hardback on 19th November 2015 - see press release below. Available to pre-order now.


Press Release

News I've been sitting on for months has finally been released. Pan Macmillan are to publish my standalone thriller THE SILENT ROOM in November of this year. I'd like to take this opportunity to say a big thank you to them and to my agent Oli Munson at AM Heath who was behind this project all the way.

Writing something new was a personal challenge for me. I had an idea for a book that simply wouldn't have worked as a Kate Daniels novel and so I decided to create a whole new set of characters to tell the story. I hope this intrigues and excites you as much as it did me when I was writing it.

As always, thanks for the tremendous amount of support I continue to receive from around the world via email and on social media. You make the hard work worth it.




Publishing Director Wayne Brookes has acquired UK commonwealth rights including Canada to the first standalone thriller from Mari Hannah. Hannah has already received critical acclaim for her series of novels featuring DCI Kate Daniels with TV rights recently sold to Sprout Pictures owned by Gina Carter and Stephen Fry. The Silent Room which features a whole new cast of characters will be published in hardcover in November of this year with a mass market paperback edition to follow in September 2016.

Mari Hannah commented: ‘I’m thrilled that I can finally talk about this standalone. It’s an exciting departure for me, the sixth novel to be published by Pan Macmillan in a relatively short space of time. The buzz around this book shows confidence on all sides. I continue to work hard on my series but I’m immensely proud to have been offered this opportunity. This thriller just flew onto the page.’

Wayne Brookes said: ‘Mari Hannah is an incredibly gifted storyteller and this novel shows exactly how talented she is. The Kate Daniels series is crime-writing at its best, but this new novel shows that she knows exactly what to do with a bigger canvas. The characters are rich in depth and the plotting is flawless. Her current fans will love this book, and it’s sure to bring many more on board.

Oli Munson, Mari’s agent, added: ‘THE SILENT ROOM – as with all of Mari’s novels – has that unputdownable quality which is the hallmark of all great thrillers. I’m delighted that Wayne and the Pan Macmillan team will be publishing and taking Mari to new heights’

 Mari Hannah

Mari Hannah was born in London and moved north as a child. Sponsored by the Home Office, she graduated from Teesside University before becoming a Probation Officer, a career cut short when she was injured while on duty. Thereafter, she spent several years working as a film/television scriptwriter. During that time she created and developed a number of projects, most notably a feature length film and the pilot episode of a crime series for television based on the characters in her book, the latter as part of a BBC drama development scheme. She lives in Northumberland with her partner, an ex-murder detective. In 2010, she won the Northern Writers' Award. She has had five novels published: The Murder Wall (which won the Polari prize), Settled BloodDeadly Deceit, Monument to Murder and Killing for Keeps.

Mari Hannah was on the 2014 shortlist for The CWA Dagger in the Library which honours an author’s whole body of work to date.

More news for Kate . . .

For visitors here who are not on Twitter, I'd like to share some exciting news. I've been shortlisted for the prestigeous CWA Dagger in the Library. The announcement was made by Dead Good Books who sponsor the award. You can view the shortlist by clicking here.

The Dagger in the Library award is all the more special because it is readers who decide which authors make the longlist. Beyond that, it was judged this year by past winner, Steve Mosby, UK librarians - Mobeena Khan, Stewart Bain, Jennifer Stewart, Sue Wilkinson - and the director of the Crime Writers' Association, Lucy Santos. I'm honoured to have made the final cut and would like to thank everyone who voted for me.

The winner will be annouced in London at the beginning of December - time and venue to be confirmed.



A double celebration!

I've been sitting on some amazing news and finally I'm able to share the press release . . .

Television rights in Mari Hannah’s Kate Daniels crime series have been optioned by Gina Carter and Stephen Fry at Sprout Pictures. The deal was negotiated by Daniel Nixon at Blake Friedmann on behalf of Oliver Munson at AM Heath & Co. 

Gina Carter says: ‘Stephen and I are thrilled to be working with Mari on bringing the extraordinary Kate Daniels to life.  I loved Kate from the start, her personal life is as captivating, intriguing and as complex as the cases she investigates.’ 

Mari Hannah says ‘From the moment I began talking to Sprout Pictures I knew we were the right fit for each other. Gina’s enthusiasm and vision for the series blew me away. The prospect of working with her and Stephen is almost too exciting for words.’ 

Four books in the award winning Northumberland based series have been published by Pan Macmillan with a fifth, KILLING FOR KEEPS, due in December.  Wayne Brookes at Pan Macmillan has also contracted Hannah for a further two more Kate Daniels books, the first of which will be published in 2016.

All I can say is, go Kate!
