According to one source the arrest warrant issued against Höltermann in 1934 remained in force throughout his entire period of exile. After World War II ended for Germany in May 1945, along with the end of the Hitler nightmare, any outstanding warrant from 1934 was of no relevance. Between 1945 and 1955 Höltermann made a number of visits to the three occupation zones , which in May 1949 constituted West Germany. A British "Naturalisation Certificate" was issued for his daughter on 5 August 1947, at which point the family were living in Kings Langley, a prosperous commuter village short distance outside London, and close to St Albans. Karl Höltermann remained England until he died a couple of weeks short of what would have been his sixty-first birthday, on 3 March 1955.
