Professor Gaskel is in his study when Lin Tang and Fu Manchu emerge. Fu Manchu hypnotizes Professor Gaskel to be under his control. They go to Fu Manchu's underground lair, where Professor Gaskel works on distilling the poisonous essence of the Blackhill poppy with Professor Muller. As they work, Fu Manchu is informed that the Essex village of Fleetwick is currently under freezing temperatures, so the poppy seed's poisonous properties will persist if used there. He makes an announcement on the radio to let the entire country know of his return, and to obey him. As a show of his power, he announces that he will target Fleetwick. Nayland Smith has British soldiers sent there to protect Fleetwick. Fu Manchu has a plane fly over the village, with the Blackhill poppy poison being sprayed onto the almost 3000 civilians and soldiers below, killing them within seconds. By this point, Professor Gaskel has also been hypnotized into committing suicide.
