It's now 70 plus years since the end of WW2 and the horrors of war have been exposed. We now have the grandchildren of Holocaust victims writing their memoirs of how their generation - the third - have been affected by atrocities of the past. But it's not just the children and grandchildren of survivors writing, there are also books by descendants of the perpetrators (or those who feel they might be the kin to the guilty.) "A Crime in the Family", by Swiss journalist Sacha Batthyany, is a look at his family's history from 1940's to the present.
