About the author

Jonathan Cox

16 books34 followers
Jonathan Cox retired from the Metropolitan Police in 2013 and within days had published 'The Blue Trilogy', in which he hoped to capture the atmosphere and attitudes of policing in the 1980s.

Only ever intended to be just the three books, such was the success of the trilogy, four sequels followed; 'When You Wear The Blue', 'We Don’t Call Them Raids’, ‘A Necessary Fiction’ and ‘Purple Cover’ - making the complete set a seven book series.

The stories are penned with a deference to realism born of personal experience and have become a cult read for serving and retired officers.

The series follows the life of PC Chris Pritchard, aka Nostrils, who joined the Met in 1983 and like the author, was posted to a police station in London's tough East End. Each subsequent book is set several years later and collectively they trace the main character's police career via his numerous postings and his slow rise through the ranks.

Pritchard is an anti-hero, fatally flawed in so many ways, yet honest at heart and always loyal to his friends.

Jonathan's career was largely spent investigating police and public sector corruption and so his books tend to slant in that direction. He also completed postings on the murder squad, several crime squads, the Met fraud squad, a witness protection unit, a financial intelligence unit, a team investigating historic terrorist offences in Northern Ireland and counter corruption surveillance teams. He worked in Turkey on a policing project for HMG and spent many years seconded to a large government department combating corruption. During several of these postings, it was necessary for Jonathan to assume covert identities.

Jonathan concludes "Being a policeman was, and still is, the best job in the world. I was privileged to work alongside some really great people, many became life long friends, a few, pretty impressive enemies. I wish both every future happiness and success."

Exceptional depiction of policing in the 1970-1980 era.

This is the fourth of the Nostrils series that I have read and I can honestly say that each and every one has been compelling reading. The author has certainly researched what it was like policing in the 70's and 80's and the story lines depict what went on in the larger city forces. I love the characters and found this diverting reading. Cannot wait to get hold of the next in the series.

Fantastic read

This is a highly entertaining read. Once i started i couldn't put it down until I had finished. The language, procedures and context appear highly accurate and believable which isn't a surprise considering the authors experience. Highly recommended reading for both police and non police

Exciting

What can I say about these books? Whether you are a cop or just like cop stories you will want to read these, but start at one because he talks about life through out the series. Don't want to ruin it for you but I have so enjoyed getting to know Chris and living through his eyes. Just my thoughts if they can make a show out of Des why not this?

I hope this is not a spoiler but the books starts off with a very vivid story about a sexual assault, it might put people off #

Chris is now married and working with a team including Bob who is in trouble and asks for Chris help
the story is sad and weird at the same time .I loved it. didn't see the tails ending coming the way it did which is good

A relatively easy read and whilst fictional, for anyone who has been in The Job over the years, there are loads of trends, occurrences & things you’ll recognise- and if you only joined within the last decade, also hopefully lots of things you won’t.
