Stoutenburg now appealed directly to him.
"What do you think of it, Beresteyn?" he asked.
"I think that my sister did hear something of our conversation," he answered quietly.
"Great God!" ejaculated the others.
"But," added Beresteyn slowly, "I pledge you mine oath that she will not betray us."
"How will you make sure of that?" retorted Stoutenburg, not without a sneer.
"That is mine affair."
"And ours too. We can do nothing, decide on nothing until we are sure."
"Then I pray you wait for me here," concluded Beresteyn. "I will bring you a surety before we part this night."
"Let me go and speak to her," urged Stoutenburg.
