Elizabeth von Arnim (1866–1941)
Writing as Alice Cholmondeley
Christine (1917)

A young violinist goes to study in Berlin in the summer of 1914. Momentous events are described in a series of letters to her mother.
Elizabeth von Arnim is well-known for writing novels in which an outsider enters a foreign culture - usually German - with comic results. This work is somewhat different: the outsider does visit Germany, but with tragic consequences. Elizabeth von Arnim did her best to disguise her authorship and strongly to imply that the story was factual, by presenting it as an epistolary novel, apparently edited by the heroine’s mother.

This conversion was inspired by the recent forum discussion on false documents.
