Author and former employee Ruth Leigh speaks at the Shard

On the 13th of November, author Ruth Leigh came to our London office in the Shard to join us for this month’s book club and give a talk about her career journey.

Ruth previously worked at Mathys & Squire as one of our support staff and we are pleased to see the success she has achieved following her time here. She has published seven books, including her main book series revolving around the life of the main character, Isabella M. Smugge, an influencer who has just moved to the countryside from London.

We had the opportunity to speak to Ruth about her journey as an author, as well as to look back at her experience at the company twenty-five years ago. In the interview, she looks at how the firm has evolved, highlighting the importance of diversity and inclusion, and shares how her rewarding her time at Mathys & Squire was, putting her in good stead for the rest of her career.


To start things off, can you give us a brief introduction?

These days I’m a full-time writer, but I only started that career full-time in 2022, so it’s still quite new. But I’ve been a freelance writer since 2008. I’ve had an interesting range of careers, looking back. I like to challenge myself, so I’ve done lots of different things.

I’ve been writing fiction since 2021. So far, I’ve written four funny, contemporary books about a TikTok and Instagram influencer, and I’m writing the fifth in the series. I’ve also written a collection of short stories around minor characters in Pride and Prejudice, a poetry book and my latest, a selection of my blogs from 2019-2023.

How long did you work at Mathys & Squire and what did you do?

I came to Mathys & Squire in 1998. Before that, I was working for the Head of Department of Psychology at UCL and it felt like it was time to take a leap. I went to an agency and the job supporting Paul was the first one that came up. I’d never worked in the private sector, and I didn’t know anything about law, but I was used to being in a supportive PA role to quite important people, so it seemed like an obvious progression.

Back then, we were all in one quite small office. I was doing admin work for Paul, but very quickly we started doing other stuff as well. Recruitment was very low key at that time, and rather one-note, so with his encouragement, I added the job of recruitment for Mathys & Squire to my list. I’m delighted to see that some of the staff I helped to recruit are still with the firm. One of our biggest clients was involved in a huge court case while I was there too, so a lot of my time was spent helping with that.

In terms of recruitment, I was very keen to make it more diverse. We were already seen as one of the more go-ahead patent firms, but more diversity was needed. Throughout my time there, I learnt a lot and met some great people, and it was hard work, but I am proud of the fact that by the time I left it looked very different from when I arrived.

In 2003, I was expecting my first child and became a consultant recruiter, working from home. That wasn’t a thing in 2003, so I was breaking new ground there as well.

What was your favourite part about working at Mathys & Squire?

I would say the social life. Our team ended up as quite a big group, so when we managed to get out and about (usually on a Friday evening), we used to have such a good time and I’m still in touch with some of them now, which is lovely.

 I do love a challenge and, at Mathys & Squire, every day there was a new one and it really helped me grow positively as a person. 

What motivated you to change to a career in writing?

It’s what I’ve always wanted. Apparently, when I was a little child, if anyone said to me, “What are you going to be when you grow up, Ruth?” I would always say, “I’m going to be a writer.” And I think it’s interesting how I worded it. I didn’t say, “I quite fancy being a writer,” or “I might be a writer;” I always said, “I’m going to be a writer.”

And I read all the time. I mean literally all the time. I’d read 15 to 20 books a week if work didn’t get in the way, that’s just my thing. It was the one subject I was naturally good at so it made sense to think that writing would be my career.

My early life wasn’t very happy. When I was 18, I ran away from home to Exeter and I thought, “Ruth, other people have dreams, but that’s not for you. Crush it underfoot and just get on with living your life, that will have to do for you.” So, I put the idea of being a writer to one side and though I would never come back to it again.

I’m glad I did things the way I did and that I didn’t plan it all out, because everything I have done has fed into my writing, including working at Mathys & Squire. I think in book five I’m going to make one of the couples my heroine knows patent attorneys. Why not?

How would you summarise the books you have written?

The main character is called Isabella M Smugge (her name spells out “I Am Smug.”). When I wrote the original blog about her, it was just for fun, creating this ludicrous woman inspired by people I’d seen on social media during lockdown. I’d see these women who were bragging about living their best lives and making banana bread and doing Joe Wicks every morning and I was so sick of it.

I created this character who lives in an incredibly privileged bubble: lots of money, perfect husband, perfect children, perfect house, babbling on Instagram and TikTok about her wonderful life. But I knew that couldn’t be the whole story. So, when I sat down to write the first book, I thought, right, she’s going to have to move out of London to a little village in Suffolk.

She’s narrating it, but she’s an unreliable narrator. She’s telling you how perfect her life is and how everyone loves her, but that’s not the case, and you start to see it through somebody else’s eyes and the cracks start to show. She changes throughout the books, but not too much, because I’m not a fan of books where someone starts off absolutely horrible and by the end, they’re everyone’s best friend. That’s not how it works. Isabella is a lot nicer, but she is still a snob by the time we get to book four.

What is the worst and best part of being a writer?

The worst part is the self-doubt – when you sit there and look at a blank screen and think, “Ruth, you’re a complete fraud. What makes you think anyone’s going to like your stuff?” You spend so much time by yourself, sitting with your own company, and those voices come in and that is hard.

The best bit is when you meet someone or you get an e-mail from a reader telling you that they loved your book and that it touched them. It really matters to me that I can make someone’s life better. People often write to me  to say that they’re in a bad place, but that my books are really helping them.

Do you think there are any similarities between your work when you were at Mathys & Squire and your work now?

I’ve never thought about that before, that’s a great question. I think that I often do difficult things in my job now – things that I thought I never could, such as going into a classroom full of 15-year-olds to deliver an inspirational workshop. I can see them thinking, “Great, another boring middle-aged woman banging on about something we hate.” But within five minutes I’ve cracked them. It’s going in and doing something that no one thinks you can do, and that’s what it was like at Mathys & Squire. Within my team, we were doing things we’d never done before, and we were looking at things which seemed unachievable or stupid to even try and trying anyway.

Did you bring anything you learnt whilst working at Mathys & Squire into your career as a writer?

I think it taught me perseverance. I already thought outside of the box, but it increased that quality.

Finally, we can’t end this without touching on the intellectual property side of things. As a writer, copyright protection plays a significant role in what you do. Did you find that you had more knowledge going into it about copyright after working here?

That’s a very interesting question. Yes, it did help me. When I wrote the novels, I was really careful.

With my Issy Smugge book, I work closely with my publisher, who has a set of house rules. When I co-founded a small press and published the other three books through them, no one was telling me what I could write. I had to really think about that, particularly with the Jane Austen book, because I had to know about the law on intellectual property, copyright and public domain. If an author has been dead for seventy years, you can use their words, but there’s something called fair use, so you can’t just quote an entire chapter, because that’s not fair.

Quite often when I’m working with other authors, they’ll ask me questions like that and I’ll find myself talking about IP, and they say, “Wow, how do you know about that?”

I was driving my teenager daughter to college the other day and she was asking what I used to do, so I started describing Mathys & Squire. And I told her about our slightly eccentric client who used to come in every two years with crazy inventions. She was slightly in disbelief that that’s what I used to do. “You did science stuff, Mum? You?” She had a point. I don’t really do science.

I once heard someone say that the patents and trade mark world is like a secret profession. If you say you work in a law firm, everyone knows what you mean. But the minute you mention patents and trade marks, people have no idea what you’re talking about. It’s niche. So, knowing what I knew about trade marks and copyright and inventive step has actually really helped because I’ve not fallen into the pitfalls that other authors sometimes do.

What advice would you give to an artist, whether they’re producing physical art, books or music, on protecting their creation?

You have to check that you’re not infringing copyright. One of the things that’s key in our industry is that you cannot legally quote song lyrics in your books. I got round that, but I did cause my agent some alarm, because I made up a band which appeared in my third book. The editor said, “ Ruth, you can’t do that,” but I explained that it was fine as I invented the band and their back catalogue (one of their songs will be trending on TikTok in book five). 


We would like to thank Ruth for taking the time to come back to Mathys & Squire. Mathys & Squire would not function without our support staff, from the people here now to those that have gone but left their mark, and Ruth is just one example of the talent and individuality which we are proud to embrace here.
