Bloody January by Alan Parks
Set in Glasgow in the early 70's and featuring Harry McCoy, the most un politically correct police offer ever, even by standards from fifty years ago.
Cracking read, helped for me by knowing so many of the city where it is set.
Part of a series of books and this is a belter of a start.
A new name to me and a welcome addition to the Scottish Noir genre. Already got February's Son (book 2) loaded onto the Kindle and ready to go.
