A quiet thriller, reminded me of Alec Guinness as George Smiley. Lots of threads gently woven together. Mistakes made by the characters added to the story. An ordinary man caught up in extraordinary circumstances. The David Chen character gentle desperate and sad to understand Megan, his whole life turned upside down by her death and the appearance of an englishman. A daughter who never really knew her Mother who had loved her but hidden so much from her Chinese family.
