Unlike yesterday, for an example of how an Edinburgh-based writer could have written something that does respect true detective traditions, I suggest Ian Rankin. And in particular, the one-off TV movie called Reichenbach Falls.
Despite the title, it was set in Edinburgh and the plot was embedded in the city. But obviously (given that title) it is as much a tribute to Sherlock Holmes as is House MD. But it's also almost a time-shifting historical fantasy, and it's clear that I like those.
From what I recall, it did have the gritty realism that was missing from the Botswana story. It also had a suitably convoluted plot and twists to the bitter end. And it might even have had some boobs too.
