The 1930s were the studio system at full power, with sound now fully integrated and the Production Code arriving mid-decade to sharply narrow what films could depict. It's the decade of the Universal monster cycle, screwball comedy, and the first Technicolor spectacles.
Mystery films are structured around withheld information, trusting the audience to work alongside the investigator. The genre ranges from cozy whodunits to bleak, unresolved character studies.
