confine yourself to the necessary details."
"You will see that it is necessary. To-day my wife fell down in a faint in the room in which I keep my wares, and she cut her lower lip upon this cursed dagger of Almohades."
"I see," said Douglas Stone, rising. "And you wish me to dress the wound? "
"No, no, it is worse than that."
"What then?"
"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?"
"No more than in a snake-bite. It is too subtle and too deadly."
