The Night Manager is Jonathan Pine, and we learn a lot more about his background in the novel than comes out in the series. He is a loner, always has been, and led a very transient sort of life that had him in the army fighting in Northern Ireland, and now has him as the night manager for top notch hotels. While the manager of the Nefertiti Hotel in Cairo, he meets and falls in love with a woman, Sophie, who entrusts some papers to him. Her subsequent death lies heavily on his conscience and when he gets the opportunity some years later to avenge her death, and put away for good the evil Richard Oswald Roper, arms dealer operating as an industrialist specialising in agricultural equipment, he takes it. He is recruited by a spying/espionage arm of the British government, handled by Leonard Burr, who has been trying to get Roper for years. But as it emerges, Roper is fiercely protected by interests high up in the government, and so the spying takes interesting turns, the stakes are higher, and it is all a race against time. How long can Jonathan keep up the subterfuge? How will Burr and his circle manage to out trick their superiors? Will Jonathan get the girl?
Fantastic, awesome stuff. I have read a few Le Carre novels over the years, this is outstandingly the best. If you are liking the series, read the book. So worth it.
