Mystery of Marie Roget

Maria Montez is Marie Roget. She vanishes, then reappears, then vanishes again. Some people think she will reappear again, but not police chemist Patric Knowles, who wanders around annoying police prefect Lloyd Corrigan, because he's always right.

Poe's short story was based on a real murder in New York, which he moved to Paris and actually figured out. Nothing loath, the folks at Universal kept the title, Dupin's last name, and little else. Instead, Knowles plays Dupin as a variant of Holmes, but much more annoying because he saunters. Corrigan is intended to be his Watson. A key clue is kept out of the audience's sight until after everything is solved. With Maria Ouspenskaya, John Litel, Edward Norris, and Nell O'Day.
