In the 1930s and 40s, Hollywood made hundreds, if not thousands of cheap B-mystery movies. Most have a certain sameness about them--and "The Case of the Black Parrot" is no exception. What do they have in common? Well, usually the police are pretty dim and it takes a non-professional (often a newspaper man or woman) to solve some murders. They also usually have the most convoluted plots and schemes. Because this film is so typical, I cannot highly recommend it...but it's not terrible.
The case involves a piece of furniture being shipped from France to the Unites States. But later, folks involves with it start dying...with marks much like snake fangs on the back of the hand of the victims. So, it's up to (naturally) a bright newspaper man (William Lundigan) to put the clues together and capture the baddie...though the baddie pretty much just turns himself in at the end. Few real surprises and, of course, a fantastical sort of way of killing people.
