Hotel with suicides in the same room

Looking for the name of a film made probably in the sixties about a hotel that has had a suicide in the same room every Friday evening. A man comes to investigate by staying in the room, and looking out of the window, there is a woman across the courtyard who hypnotizes him into killing himself. The film might have been Finnish.

@MovieGal this sounds like it is right up your alley.

If it's from the 60s, I wouldn't know it.

@pahaK may.

I've changed the thread title to be more descriptive, per the warning beneath the title field:

Can't think of any Finnish film that even remotely fits the description. Honestly, it doesn't sound like something done in Finland during the '60s.

Not a film I've seen, but could this be it:

I saw it on television in Sweden in the 1970s

I don't know, but it sounds good.

should be in black and white though.

I think it was in black and white

How do you remember that it was every Friday specifically?
Could it not have been every Thursday?
or every alternate Friday?

I just remember certain things .Someone told me the gist of it

And you don't think it's Dr. M?

I saw it on television in Sweden in the 70s.

And you're sure it was a film?

Was it in color or black and white?

Do you remember anything else about other characters or what any of them look like?

I found Horror Hotel although it isn't Finnish.

That's all I could find...

I just searched elonet (a Finnish site with a database that should contain every Finnish movie) and there was no matching film made between 1900 and 1979 (my search wasn't even strict as the only keyword I searched was suicide). I'd say it's 99% certain that the film in question is not Finnish.

When I followed the link to see what Dr. M was about, it said it was based on a Dr. Mabuse story -- so maybe you saw a different version of the same story?

Maybe it was made for television. I'm not absolutely sure it was Finnish.

Black and white. The man called in to investigate is given a gun, and at one point the woman across the courtyard hypnotizes him into disconnecting the telephone.

No it's a different story
