Street corner dad

the long version

"It's war-time and bombs are falling all over the city. Jimmy and his sister Molly are almost the only children left after all the evacuations. But despite the war raging around them, they're happy because all the family are still together. But when tragedy strikes, strict old Nan turns all her anger on their father and forbids him to see the children ever again. Can Jimmy and Molly figure out a way to see their father?"--Publisher's website.
