From a news-story by Warren Armstrong
In July 1940 the Sunday afternoon calm of a Stockholm suburb was disturbed by a rumour of murder - a murder that could not be traced. The informer was a twenty-three-year-old clerk named Hans Krantzer.
Warren Armstrong, a Liverpool journalist who was in Stockholm at the time, covering the war news, investigated Hans Krantzer's story and uncovered one of the strangest murder cases on record: Stockholm police dossier 4067.
