The People's Book Prize Finalist 2019-2020

’A vision of the future that both chills and entertains.’ Jake Kerridge (Sunday Express Magazine)

You can’t get away with anything. Least of all murder.

DI Clive Lussac has forgotten how to do his job. Ten years of embedded technology – ‘iMe’ – has led to complete control and the eradication of crime. 

Then the impossible happens. A body is found, and the killer is untraceable. 

With new partner Zoe Jordan, Clive must re-sharpen his detective skills and find the killer without technology, before time runs out for the next victim…

Leading the trend in speculative crime thrillers, Jem Tugwell’s thrilling and thought-provoking debut sits alongside Black Mirror and The City and the City in a compelling exploration of our near future. Proximity draws on Jem’s 20 years of professional experience as a software developer in the city to give an unnerving insight into how our world might be transformed by the rapid advance in embedded technology and fitness trackers.


‘Tugwell brings to life his exhilarating and provocative debut crime thriller with a twist.’ The Malestrom, 4 of the Best Beach Reads: Summer 2019

‘An ingenious and highly plausible look at crime in a future with 100% surveillance’ Claire McGowan, Best selling author

Very topical, terrifying, perfect concept for a crime novel’ Stav Sherez, Award winning author

Darkly twisted crime novel in a future that seems to grow closer every day. Fantastically imaginative and gripping.’ Angela Clarke, Sunday Times bestselling author

5* Review ’The writing hurtles along like a runaway train and you can barely pause for breath. What renders it original and ingenious is the background of embedded technology called ‘iMe’ (how perfect is that?!) It’s a crime thriller and it is very thrilling.' Gill Chedgey (NB Magazine)

5* Review ‘I must admit that I finished the book with a prayer that I will never see something like iMe in my lifetime - the idea is just too terrifying’ Breakaway Reviewers

‘5*s from me as the storyline is brilliant…Plenty of discussion topics here for bookclubs!’ EmmabBooks

'Proximity hits hard and cold right to the heart of what could be our future, and this knowledge makes this book one of the scariest I have ever read. I don’t care for horror. Just give me a speculative novel shaping a future so realistic I don’t even need to close my eyes to imagine it, and I’m sold. Sold and freaked out. Jem Tugwell’s outstanding description of years to close to ours to my taste left me speechless.’ Meggy Chocolate’n’Waffles

'A brilliant book, an excellent thriller and 100% entertaining. Highly recommended. Really can’t wait for a follow up! Genius.’ Books from Dusk Till Dawn

'An enjoyable and somewhat unnerving peek at what technology could be like in our future. “Proximity” is fast-paced, imaginative and could easily be featured as the next episode of “Black Mirror”. It’s a big 5 stars from me!' What Rebecca's Read

'You won’t be able to put Proximity down, and you’ll be happy about it. So, in conclusion, when Proximity becomes the bestseller it deserves to be and Jem Tugwell is the name everyone’s talking about, just remember, you heard it here first.' Dorset Book Detective

What some of the Amazon readers are saying:

5* ‘This is a really creative idea expertly executed in a fast paced thriller you won't be able to put down!’

5* ‘What a fantastic read. Great story. Great pace. Great drama and suspense.' 

5* ‘Outstanding. I couldn't set it down…’

5* ‘Enthralling and thrilling story left me always wanting to read 'one more chapter.'
