The Talons of Weng-Chiang
By Robert Holmes
“I don't know who's a blackguard. Some slavering gangrenous vampire comes out of a sewer and stalks this city at night, he's a blackguard. I've got to find his lair and I haven't got an hour to lose.”
The Doctor brings Leela to Victorian London to see how her ancestors have lived. What happens next is just typical luck for The Doctor as they get involved with a case that involves the Tong of the Black Scorpion. There also appears to be a connection with a a slew of woman disappearing and it seems to all center around Jago’s theatre and his main act Li H’sen Chang. It appears that Chang is working for the 51st Century criminal Magnus Greel or as he is known now Weng – Chiang.
With the aid of giant sewer rats and the murderous Peking Homunculus Mr. Sin it appears that Greel might be able to get the time cabinat working again and get the Zeta beam to take him home. Unfortunately this will cause great repercussions to Earth as the beam is spread thin and will not work. So it is up to The Doctor and Leela and the aid of his two new friends Jago and Lightfoot to stop the villainous Greel and save the Earth in the processes.
