Running behind again - but I read this book recently and really found it involving and extremely interesting - more asap.
From the Blurb:
1222 metres above sea level, train 601 from Oslo to Bergen careers off iced rails as the worst snowstorm in Norwegian history gathers force around it. Marooned in the high mountains with night falling and the temperature plummeting, its 269 passengers are forced to abandon their snowbound train and decamp to a centuries-old mountain hotel. They ought to be safe from the storm here, but as dawn breaks one of them will be found dead, murdered.
Opening Lines:
As it was only the train driver who died, you couldn't call it a disaster. There were 269 people on board when the train, due to a meteorological phenomenon that I have not yet understood completely, came off the rails and missed the tunnel through Finsenut.
