[Tip of my tongue...but very little to go on]

I think that's a winner fellows.  Thanks very much for the help!

[Tip of my tongue...but very little to go on]

I cannot for the life of me remember much about this film.  Definitely shot in black and white.  My best recollection of the plot is that a policeman or private investigator impersonates a woman's brother in an attempt to force her to confess to the murder of said impersonated brother.  I think it took place in either the south of France or possibly Tuscany?  Thats...about it.  

 

Any help is greatly appreciated!
