I live in Germany, I'm British and my wife is german, I have three children. My screenplay is about the holocaust, so it's more fact than fiction. It's based on real-life characters, two German Jewish women who were deported to a polish work camp and then to a death camp. The story revolves around these two and two other characters, a German gentile woman who kept a package of valuables safe for one of the women, a crime at that time, the punishement being internment in a work camp for dissidents, and the woman's husband, a cipher clerk, forced to work for the german army (refusal meant death) until he manages to desert successfully. The story ends with the opening of the package and its deleivery to the Jewish memorial museum in Berlin.
It is (will be) adapted from the story of the same name, 'Perdition's Companion'. Available on Amazon as an e-book.
I am not sure if this genre is sought after or not. As for the holocaust, programmes are shown Mon - Fri on German public TV; greusome, tragic and unforgetable.
