I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
This seems so classic.
All the suspicious parties ensconced in an old manor on the countryside during a snow storm.
And a serial killer on the loose.
I was pretty sure about the culprit early on, but nevertheless a very satisfying read.
