Because it's that time of year, I've read A Christmas Carol for the umpety-umpth time.
How does it get better everytime, even though it's so familiar ...
Now reading Killer Genesis - by Axel Kilgore ... pen name for Jerry Ahern
Sundae, I really enjoyed
More Blood, More Sweat, and another Cup of Tea, but it might not do as well for you ... it's a collection of blog entries by a British Emergency Medical Technician.

I was looking over the Amazon.co.uk offerings, didn't know if you'd read Stieg Larson's Millenium trilogy yet. The first one takes a bit of getting into, and there are some nasty bits, but overall, it's a solid mystery.

I found a website that lists books set in Scotland.
