Das Raetsel der roten Orchidee on AllMovie

Even while a series of British second features based on the works of Edgar Wallace was flourishing in the 1960s, Germany was grinding out its own Wallace series. Secret of the Red Orchid top-bills British actor Christopher Lee in a story of a joint effort between the FBI and Scotland Yard. The target of these combined forces is a far-reaching crime syndicate. The stellar international cast includes Klaus Kinski (a semi-regular in the Wallace series), Marissa Mell, and silent film veteran Fritz Rasp. Secret of the Red Orchid was originally titled Puzzle of the Red Orchid.
