Summary The hunt for the fourth segment of the Key to Time brings the TARDIS crew to 1930s Shanghai: the Tongs pursue their own agenda in the city's illegal clubs, while the Japanese Empire looms in the background. Manipulated by a mysterious enemy, the Doctor must follow the Dragon Path - a side effect of a terrible experiment from the future. And who is the beautiful Hsien-Ko and the small child that accompanies her? Plot While stealing a priceless work of art from the Palace Theatre Museum, thief Lucas Seyton, the Fallen Angel, stumbles across another robbery in progress. He is unable to prevent the thieves from killing the caretaker and making off with another exhibit, but he does find a clue: a matchbook from the Club Do-San in Shanghai, which is owned by a friend of his.

Inside the den, he finds the body of a European male who appears to have been stabbed to death, but the blood trail which indicates he was killed somewhere other than this room leads straight to a solid wall.
