If you’ve nae already read it, ATT min, Crucible of Secrets by Shona MacLean, a Banff quine if my memory’s in gear, might be right up your Wrights and Coopers Place. It’s set in 1631, and the Marischal College librarian has been found dead. There’s a good bit of to-ing and fro-ing between Marischal and Kings College, slums, hoorhooses and taverns in Putachieside as the investigation goes on.

I got a proof copy from the publisher, and caused a bit of a panic when I found a plot error suggesting that some official wifie was shagging her brother (had it been set in Huntly naebody would have batted an eyelid). I hope they made the edit before they published it.
