In 1977, she started studying economics at the University of Göttingen. At the height of the fear of communist terrorism in West Germany, she fled to London in 1978 after her family was told that the Red Army Faction (RAF) was planning to kidnap her due to her being the daughter of a prominent politician. She spent more than a year in hiding in London, where she lived with protection from Scotland Yard under the name Rose Ladson to avoid detection and enrolled at the London School of Economics. A German diminutive of Rose, Röschen, had been her nickname since childhood, while Ladson was the name of her American great-grandmother's family, originally from Northamptonshire. She said that she "lived more than she studied," and that London was "the epitome of modernity: freedom, the joy of life, trying everything" which "gave me an inner freedom that I have kept until today." She returned to Germany in 1979 but lived with a security detail at her side for several years.
