The Golden Scorpion
The Golden Scorpion linked the story lines developed in the Yellow Claw (1915) with Dr. Fu Manchu who appears but is not named. "He wore a plain yellow robe and had a little black cap on his head. His face, his wonderful evil face I can never forget, and his eyes -- I fear you will think I exaggerate -- but his eyes were green as emeralds!"
