What Have You Done to Solange? (1972)

This giallo thriller has a straightforward premise: a private school teacher becomes a murder suspect when he can’t provide an alibi for a killing — because he was in the arms of one of his students. The manner of death remains gasp-inducing, all these years later.

What Have You Done with Solange has a very dated approach to student-teacher relationships, and maybe all relationships, that adds to its unsettling atmospherics. A captivating film.
