Liam, who is a professor at the University of New Mexico, contacted me yesterday. He is teaching a course in Giallo cinema (indeed this sounds interesting), and would like to gather information about Massimo Dallamano's "What have you done to Solange?" for a lecture next week.
If some of you have already investigated this giallo, or if you have seen a good analysis of it on the web, please post a comment on this article or contact me by email, I will be happy passing your precious point of view to him.
Many thanks in advance.
