Half-Life: 1. Daughter of Radium

Drawn to a family legend about his German-Jewish family’s dramatic escape from Nazi Germany in 1936, the writer Joe Dunthorne accidentally discovers a far more disturbing history.

A conversation with his granny, who spent her childhood brushing her teeth with the radioactive toothpaste her father Siegfried manufactured, leads Joe to finally read his great-grandfather's nearly 2000-page long unpublished memoir. Hidden on page 1692 he finds an unsettling confession.
