'Without quite realising that I would do it until it happened, I raised myself on my toes and kissed his frozen cheek. In Paris, it would have been an unremarkable gesture. In Alexandria, an invitation. I still had no idea about London.' The London winter of 1947. As cold as St Petersburg during the Revolution. The Karenins keep their vodka under the layers of snow in their suburban garden, in bottles entombed like their Russian past. But when a young Frenchwoman arrives to work as a companion to the aged 'Monsieur Ka' he begins to tell his story... Albertine is the wife of a British army officer who is often abroad on covert government business. Lonely, yet eager to work, she begins to write Monsieur Ka's life story a as a secret gift to him, and even learns his mother tongue. To her ear it is like 'the sound of falling snow'. As she is drawn into Ka's dramatic past, her own life is shaken to its foundations. For in this family of former princes, there are present temptations which could profoundly affect her future.
