A FIFTY-YEAR-SILENCE is the deeply involving account of Miranda Richmond Mouillot's journey to find out what happened between her grandmother, a physician, and her grandfather, an interpreter at the Nuremberg Trials, who refused to utter his wife's name aloud after she left him. To discover the roots of their embittered and entrenched silence, Miranda moves to their stone house; immerses herself in letters, archival materials and secondary sources; and teases stories out of her reticent grandparents.
