Read the reviews on Kindle. Those who've read the book say it is a fabulous read. And I agree. What can be more fun that a naïve, if a little lazy, new PC is thrown into a situation where a lot of colleagues are corrupt? If you also like wildlife books, then you'll also love this book as it shows predators at work.
If you have self doubt, wonder if you are good enough in your role, then you will find Both Sides of the Force will show that even the barely adequate can get by.
Whilst it covers a shameful period of policing in London, the wry humour will make you laugh.
