Detective Lloyd (1931) is a 12-chapter Universal movie serial.

A co-production between the American company Universal and the British company General Films, it was filmed entirely in Britain with British and Commonwealth actors.

Although a print was shown on British and Swedish[2] TV as recently as the 1970s, the film is now considered lost.

Detective Lloyd battled a villain known as the Panther in this serial.

Material from the serial was edited into a feature film version called The Green Spot Mystery (1932), which is also a lost film.
