"By whom?"
"By the assassin."
"And who is the assassin?"
"I can't say. But if use is made of that confession either you or I will learn who killed Mrs. Jersey."
"Why you or I?"
"Because we alone can make use of the confession and pay money for it. The thing would be no use to any one else. But I now understand Mrs. Jersey's possession of the house. Were you in it on that night?"
Derrington looked at Brendon and hesitated. Then in strange contradiction to his usual manner, he turned away his face. "I decline to answer that question," he growled.
"But I saw you," insisted George.
"You saw--there is nothing more to be said. Hold your tongue."
"Willingly," said George, politely, "if you will silence Mrs. Ward."
