I thought this was a fantastic episode, one of the best ever! There was some really good research involved, and it wasn't presented in a too heavy handed way as can sometimes be the case.
I also wondered how Eva had managed to marry into a prominent orthodox jewish family given her family background, which surely must have been well know in the locality.
And Alex was fabulous!
Off to do a bit of research of my own now hopefully to fill in some of the gaps!
