She becomes involved with a young German doctor, Oscar Raeder, who has been studying in Dublin since before the war, and supports him when he is suspected of murdering a prostitute. A second murder - this time of a German spy - is also discovered inconveniently near where Raeder lives.As the horror of the concentration camps filters through, Raeder becomes the focus for hatred of Germany. Aghast at the prejudice he encounters, and convinced that Raeder is no murderer - Honor agrees to help him return to Germany, even though she knows this may mean the end of their relationship.
