"Yes."
"You are to watch me, for I will be visible to you."
"Yes."
"And when I raise my hand—so—you will throw into the room what I give you to throw, and will, at the same time, raise the cry of fire. You quite follow me?"
"Entirely."
"It is nothing very formidable," he said, taking a long, cigar-shaped roll from his pocket. "It is an ordinary plumber's smoke-rocket, fitted with a cap at either end, to make it self-lighting. Your task is confined to that. When you raise your cry of fire, it will be taken up by quite a number of people. You may then walk to the end of the street, and I will rejoin you in ten minutes. I hope that I have made myself clear?"
"I am to remain neutral, to get near the window, to watch you, and, at the signal, to throw in this object, then to raise the cry of fire, and to wait you at the corner of the street."
"Precisely."
"Then you may entirely rely on me."
"That is excellent. I think, perhaps, it is almost time that I prepared for the new rôle I have to play."
