Sam and Alf are friends. Even though they are only 14, they work together for 60 hours a week. This is London's East End in the 1930s, and issues such as racial tension, gang crime and right-wing antagonism were as relevant then as they are today. At first it doesn't matter that Sam is Jewish and Alf is Irish, but Alf joins Mosley's Blackshirts and a friendship turns to hate. Previously published by Barrington Stoke as They Shall Not Pass, this is a powerful story that reaches its climax in the 1936 Battle of Cable Street.
