Memoirs of a Jew who was born in 1919 in Frankfurt to a wealthy family and renamed Otto after his father, who died young. First relates the stories of a number of Jews who contributed to German society; these accounts often end with brief details of deaths in concentration camps or by suicide. After the Koch family jewelry store was Aryanized, the extended family faced the dilemma of how and when to emigrate. In 1935 Otto went to study in England, returning home on holidays until 1938. Chs. 17-18 (pp. 91-103) are devoted to events of 1938, when his mother, who had returned to Frankfurt from Switzerland, succeeded in emigrating. Otto, who was studying at Cambridge, was arrested as an enemy alien by the British, interned, and then sent to Canada, where he and other Jews, along with Nazis and POWs, were imprisoned for over a year and a half. The policy of incarcerating Jews in Canada was not considered unreasonable by Koch and others. They attributed it to fear and obtuseness; antisemitism may have been a factor but not a major one. Koch gives a full account of the German Jews' incarceration in "Deemed Suspect: A Wartime Blunder".

This new novel extends Koch's achievements in his previous novels and takes the reader to Koch's native Germany. Set in Weimar and Frankfurt in Germany, in the pivotal years 1927 and 1928, the novel is triggered the International Music Exhibition of 1927 "The Summer of Music. The reader is introduced to three main characters: Hanni Geisel, an amateur musician and hostess of star-studded Saturday 'dejeuners'; her lover Erwin Herzberg, the editor of the culture sections of the Frankfurter Zeitung; and Hanni's husband, Dr. Hermann Geisel, a successful lawyer and art collector. They constitute the Weimar triangle of the title. Koch again uses a multi-format narrative technique so highly praised in the German reviews of Recollections, including stories, excerpts from imagined memoirs, invented diaries, letters and even a synopsis of a never-produced operetta about the failed Hitler putsch of 1923, Putsching with Putzi.
