Young Adolf by Beryl Bainbridge
Paranoid, wilful, lazy, the young Adolf Hitler turns up in Liverpool to stay with his brother Alois and sister-in-law Bridget. Hailed by Alois as a student and an artist, Adolf soon irritates his family beyond measure by his constant sponging and his tendency to get into serious trouble with the English. Surely this is a young man who will never amount to anything.
