just watched secret army 'collaborator' this truly was television at its best
absolutely captivating, great credit to uktvhistory for the re run.
as to your question the only other series i can think of at the moment is one called
manhunt, set in france starring the late peter barkworth and alfred lynch.
this was on independent tv but was very similarly set to secret army, don't know if its available on dvd
but have glimpsed it since the sixties, on the internet sites.
