Ellis shook his head doubtfully. "I think not, Harry. She might get him put in prison; but then, in revenge, he could hang her sister. No, Busham is all right on that point; he would not have burnt the will had he not known how to protect himself."
Cass stared at the ceiling and mused for a few moments. "From what you tell me of Zirknitz," he said at length, "I am not inclined to trust that man. He is too thick with Busham, and, moreover, he is a venal creature who would sell any information for money."
"Do you think he is in league with Busham?"
"I would not put him on so high a plane. I think he is the tool of Busham, though. I should not be at all surprised to find the whole of this mystery traced to that Esher Lane office."
"What! Do you think that Busham is guilty?"
"No; he is too clever to risk his neck."
"Zirknitz?"
"No; the Austrian is a coward."
"Then what do you mean?"
"I hardly know how to explain," said Cass. "I fancy old Moxton's money is at the bottom of all this business, and that Busham is the moving spirit. Watch him, Bob, he is the clue to the mystery."
