“The Metropolitan Police Service is still, despite what people think, a working-class organisation and as such rejects totally the notion of an officer class. That is why every newly minted constable, regardless of their educational background, has to spend a two-year probationary period as an ordinary plod on the streets. This is because nothing builds character like being abused, spat at and vomited by members of the public.”

“I gave the prescribed Metropolitan Police "first greeting"."Oi!" I said "What do you think you're doing?”

“There was also a great absence of people, including behind the mahogany-topped reception desk. Now, there’s a time when an unlocked premises is a positive boon to a police officer as in – I was just looking to ascertain the whereabouts of the proprietor when I stumbled across the Class A controlled substances which were in plain sight in the bottom drawer of a locked desk in an upstairs office, M’lord.”

“Despite my mum being from a small village in the middle of a forest, I'm not a country person. I don't like my bacon sandwich to be curiously snuffling at my fingers. But sometimes being police means holding your breath and fondling a pig.”

“It’s a truism in policing that witnesses and statements are fine, but nothing beats empirical physical evidence. Actually it isn’t a truism because most policemen think the word ‘empirical’ is something to do with Darth Vader, but it damn well should be.”

“If you ask any police officer what the worst part of the job is, they will always say breaking bad news to relatives, but this is not the truth. The worst part is staying in the room after you've broken the news, so that you're forced to be there when someone's life disintegrates around them. Some people say it doesn't bother them - such people are not to be trusted.”

“Not being invited in is one of the boxes on the “suspicious behavior” bingo form that every copper carries around in their head along with “stupidly overpowerful dog” and being too quick to supply an alibi. Fill all the boxes and you too could win an all-­expenses-paid visit to your local police station.”
