Almost a decade into the streaming revolution it’s remarkable that almost 10 million people interrupted their (admittedly locked down) Sunday evenings to settle in to watch the latest series of Jed Mercurio’s police corruption drama Line of Duty — more than double those who tuned into the once unsurpassable Christmas Day soap specials. It’s a testament both to Mercurio’s skill in crafting twist-laden event TV and the perennial appeal of the police procedural.

Why do we love cop shows so much? There’s the appeal of the macabre. Rubbernecking at a real crime scene may be frowned upon — but poring over livor mortis, strangulation marks, and puncture wounds from your sitting room is significantly less uncouth.

Others make it blindingly obvious who it is at an early stage, through casting if nothing else — even while our protagonists beaver away at the case.

Instead it’s the thrill of the chase alongside characters we like. The likes of Morse, A Touch of Frost, Scott & Bailey and New Tricks may seem to have little in common. Three focus on cantankerous old codgers showing youngsters how it’s done, the…
