"These daggers are poisoned."
"Poisoned!"
"Yes, and there is no man, East or West, who can tell now what is the poison or what the cure. But all that is known I know, for my father was in this trade before me, and we have had much to do with these poisoned weapons."
"What are the symptoms?"
"Deep sleep, and death in thirty hours."
"And you say there is no cure. Why then should you pay me this considerable fee?"
"No drug can cure, but the knife may."
"And how?"
"The poison is slow of absorption. It remains for hours in the wound."
"Washing, then, might cleanse it?"
