2.5 stars rounded up. I'm not even sure what to say about this one. It's okay, but not enthralling? This installment of the series diverges from the usual library setting, and for awhile I thought that it was going to be a train mystery a la Murder on the Orient Express. Honestly, I think that would have been better than coming up with a reason for the train and all the suspects it contains having to stop in Briar Creek and get stranded in a blizzard. There were also a distracting number of callbacks to previous books.
