"It is in the interests of all parties," he said in his slow, halting way, "that the truth should be known, both for the sake of my honourable master, Lieh Jen, the Hunter, and his honourable Little Lady."

He took up his knife and bent over the terror-stricken man.

"For God's sake don't, don't," half screamed, half sobbed Milburgh.

"This will not hurt you," said Ling Chu, and drew four straight lines across the other's breast. The keen razor edge seemed scarcely to touch the flesh, yet where the knife had passed was a thin red mark like a scratch.

Milburgh scarcely felt a twinge of pain, only a mild irritating smarting and no more. The Chinaman laid down the knife and took up the smaller bottle.

"In this," he said, "is a vegetable extract. It is what you would call capsicum, but it is not quite like your pepper because it is distilled from a native root. In this bottle," he picked up the larger, "is a Chinese oil which immediately relieves the pain which capsicum causes."

"What are you going to do?" asked Milburgh, struggling. "You dog! You fiend!"

"With a little brush I will paint capsicum on these places." He touched Milburgh's chest with his long white ringers. "Little by little, millimetre by millimetre my brush will move, and you will experience such pain as you have never experienced before. It is pain which will rack you from head to foot, and will remain with you all your life in memory. Sometimes," he said philosophically, "it drives me mad, but I do not think it will drive you mad."

He took out the cork and dipped a little camel-hair brush in the mixture, withdrawing it moist with fluid. He was watching Milburgh all the time, and when the stout man opened his mouth to yell he thrust a silk handkerchief, which he drew with lightning speed from his pocket, into the open mouth.

"Wait, wait!" gasped the muffled voice of Milburgh. "I have something to tell you—something that your master should know."
