True crime dramas have an unfortunate habit of making us feel… well, grubby, to put it bluntly. How could poring over all the grisly details of someone’s murder not?

For years, these shows have made us feel as if we’re rifling through someone else’s dirty laundry. They dangle violence tantalisingly before us, as they shove the lives of the victims to the side in order to transform their killer into a fully fleshed-out protagonist.

Thankfully, though, the manner in which TV studios are approaching the genre is now changing, and for the better. Indeed, all one needs to do is look at the likes of The Serpent and The Pembrokeshire Murders, both of which have chosen to shine their spotlight on heroic individuals who worked tirelessly to bring down famed serial killers, to see that.

And now the BBC has brought us yet another compassionate (yet still thoroughly compelling) true crime series.
