Today sees the launch of debut cosy crime novel, Death By Numbers, written by friend of the Book Edit Jo Cunningham. We couldn’t be happier for Jo’s publication news. She’s not only hilariously funny - in person and in print - she’s also a thoroughly lovely human being, and we can’t wait to read her book.

When did you first realise you wanted to be a writer?
Glossing over my dubious childhood poetry and notebooks full of random jottings, I didn’t start writing ‘seriously’ until my early thirties. I went on a beginners Arvon course for a week, with no expectations, and by the end of the course I was hooked. One of the tutors on the course recommended the courses at City University for novice writers and…
Who are you currently reading?
I have just finished reading The Misadventures of Margaret Finch by Claire McGlasson which is a beautifully written novel about a young woman in 1930s Blackpool who questions how she observes others, and herself. Next up, is Kala by Colin Walsh – I’m going to hear him speak about the book soon, so that’s exciting. And after that on my TBR pile is Monumenta by Lara Haworth – after hearing Lara’s amazing talk at the recent City Writes event, I had to get her book!
You’ve studied creative writing and also worked hard at the craft of writing on your own. What’s been the most useful thing you’ve learned about writing a novel?
Yikes – just one thing? At the moment, I’m in an editing phase, and as I re-read each scene, I ask myself ‘Does this scene earn its keep?’ – is there enough happening to keep it – does it push the story and the characters forward? If the answer is ‘No’ then I either need to rework the scene or ditch it.
What kind of qualities does a writer need?
Persistence and resilience. It took me many years from starting to write novels to reach the publication stage. The main thing you must do is finish the novel. I know that sounds glib, but not everyone does. The next thing is dealing with rejection. I wish had some words of wisdom on that. Rejection hurts, but you somehow have to get over it and keep going. Even now I’m at the publication stage, I know there will be more of that to face in the future but… you only need that one person to say ‘yes’!
What made you write a cosy crime novel? What is it about the genre that appeals to you?
Back in 2017, I’d just put another novel in the ‘bottom drawer’ and wanted to start something new. I’d been reading Douglas Adam’s Dirk Gently detective novels and was inspired to start on a humorous detective book. I read and watch a lot of cosy crime – there’s something oddly comforting about knowing everything will be resolved and usually there’s a good dose of humour included.
Can you tell us about your path to publication?
I’d describe it more as an obstacle course where I created some of the obstacles. For my first three novels, I didn’t bother with looking for an agent or publisher – I didn’t think they were of a good enough standard and perhaps I was trying to put off being rejected… they went straight in the bottom drawer. But the fourth novel I did send round to five or six agents. I got a couple of personal replies in amongst standard rejections and tumbleweed. I think I should have been a bit more persistent at this stage – please see my own advice about writer qualities above. Anyhow… when it came to the fifth novel, Death by Numbers, I decided I would really go for it. I sent the novel out in small batches to agents. I started to get full-read requests which boosted my confidence – this is when the agent has enjoyed the excerpt that you’ve sent and now wants to read the whole manuscript. Eventually I got an offer from my amazing agent Marina de Pass at The Soho Agency – from sending in a submission to the ‘slushpile’ – so yes, it can happen.
What advice would you have for someone starting out writing a novel?
I’ve benefitted enormously from taking courses, getting feedback at workshops, and reading books to help improve different writing skills – structure, character, productivity. But there were times when I had step back and work out what was going to work for me. I guess my advice is that you have figure it out so that you create your own advice for yourself.
What are you working on now?
I’m currently finishing off a batch of edits on the second book in the cosy crime series featuring Una, an actuary and a detective. It’s called Pet Hates and is due to come out in August 2025. Writing the next book in series has been a learning curve, as it has to be standalone but still have some touches that make it feel there’s some continuity for anyone who’s read the first one.

Thanks so much, Jo! We can’t wait to read the novel!
