“What signal?”
“He will press his left hand over his eyes, and say, ‘Justice calls.’”

I have trusted you, not because I was forced to trust some one, but because your face has told me you may be trusted.”
“Thank you, monsieur.”
Laforce waved his hand.
“It is I who owe you thanks, Monsieur Merriwell. I hope to see you here to-morrow evening at this hour.”
“I hope you may.”
“Till then, guard that tiny ball with your life, for it may give life and liberty to the innocent man on Devil’s Island.”
