Bit of a bump, this, but it saves creating a new thread.
I recently read a thing called Bloody January, by Alan Parks set in early 70s Glasgow.
It will inevitably garner comparisons with Rebus, but Harry McCoy, Parks' anti-hero copper is deeply damaged in a way that Rebus never was.
Anyway, this is a page-turner that delivers the goods in full. I won't say too much about the plot, except to say that the author was obviously thinking of both the Jimmy Savile case and the Profumo affair.
This guy is one to watch - I'd get in on the ground floor if I was you.
