A suspense bitish tv series, many years ago, in black and white...?

Question

I watched it on TV in Argentina, I remember that it was called "Private Session", or something like that, it began with a mansion painted in white with those heavy doors, and some steps in front, and a garden, of course.

One of the chapters was called "The murderer with the red carnation" - i loved that!!! I was only a child, i hardly can remember, but i think this was an excellent suspense TV Series, with the style of "The Revengers", more or less. Does anyone know what series i am talking about? And who were the actors there??

Sorry, i wrote "Private Sessions" because it was more or less the title that was given in Spanish, but i don t remember the English exact title, but it was a British (not american) series

Answer 1

Private film or theatre I think.
