My teaser :

“With a sudden jolt the train shuddered to a halt,the brakes screeching on the tracks .
Ant and Sally woke with a start .The carriage was empty . They were the only passengers left on the train.They shivered in the icy air .It seemed  to be  much colder.Outside – the station name loomed out of the fog.This was it – the end of the line.”
