‘We want you to consider the Case Progression Unit,’ said Neblett.

The theory behind the Case Progression Unit is very sound. Police officers, so the established wisdom has it, are drowning in paperwork, suspects have to be logged in, the chain of evidence must never be broken and the politicians and PACE, the Police And Criminal Evidence Act, must be followed to the letter. The role of the Case Progression Unit is to do the paperwork for the hard-pressed constable so he or she can get back out on the street to be abused, spat at and vomited on. Thus will there be a bobby on the beat, and thus shall crime be defeated and the good Daily Mail-reading citizens of our fair nation shall live in peace.

The truth is that the paperwork is not that onerous — any half-competent temp would dispose of it in less than an hour and still have time to do his nails. The problem is that police work is all about ‘face’ and ‘presence’ and remembering what a suspect said one day so you can catch them in a lie on the next. It’s about going towards the scream, staying calm and being the one that opens a suspect package. It’s not that you can’t do both, it’s just that it’s not exactly common. What Neblett was saying to me was that I wasn’t a real copper — not a thief taker — but I might play a valuable role freeing up real coppers. I could tell with a sick certainty that those very words ‘valuable role’ were rushing towards the conversation.

‘I was hoping for something a bit more proactive, sir,’ I said.

‘This would be proactive,’ said Neblett. ‘You’d be performing a valuable role.’

Police officers, as a rule, don’t need an excuse to go to the pub, but one of the many non-excuses they have is the traditional end-of-probation booze-up when members of the shift get the brand new full constables completely hammered. To that end, Lesley and me were dragged across the Strand to the Roosevelt Toad and plied with alcohol until we were horizontal. That was the theory, anyway.
