I saw this doc about a year ago, so I’m going from memory. Forgive me if I get some things wrong.
Adamchak & Nye is the name of a San Francisco detective agency. That’s Raoul Adamchak and Bill Nye. The two are partners, but Raoul doesn’t like Bill much. A mysterious woman, who goes by the name of Miss Malkan walks into their office. By nightfall everything gets weird. Bill is dead. And so is some Brit named Mark Lynas.
It seems Miss Malkan is surrounded by dangerous men. There’s Gary Ruskin, who uses gardenia-scented calling cards and Ronnie Cummins, who has an enormous girth and feigned civility. Her only hope of protection comes from Raoul who is suspected by the police of one or both murders. More murders happen and it will all be because of these dangerous men — and their lust for a statuette of a bird: the Maltese Falcon.
I don’t know. I think I might be confusing this with another film.
