Would agree there Bill . Even when reading the books , one sees Bernard Hepton's face when Esterhaze is mentioned.Bernard Hepton 19/10/1925 - 27/07/2018.
Another great actor of the old school. Colditz---Secret Army-- and my favourite's John le Carre's Tinker, Tailor, Spy And Smiley's People as Toby Esterhase. R.I.P.
