"I don't understand----"

"Don't I speak plainly?" asked Dimsdale tartly. "I said there were two cases, didn't I? Answer me, sir; answer me?"

"Yes, but----"

"There is no but about the matter, Arthur. I shall make a full explanation after I have asked a simple question."

"And the question?"

"You see, don't you, how this information places Maunders, young beast, in your power?"

"No, I don't," answered Vernon very plainly and somewhat aggressively; "if you mean that I am to use my knowledge of his falsely being accused of illegitimacy as a threat to keep him from worrying me into a partnership."

"I don't mean that in the least," cried Dimsdale warmly. "Confound you, sir, would you make me out to be no better than this spider reptile. What I mean is that you can say to Maunders that you will receive him into partnership if he hunts down The Spider and clears the character of his adopted mother. Not that Emily's character requires clearing in my eyes, mind you. But we must consider the limitations of human nature, my boy, and place Emily, like Cæsar's wife, above suspicion. Now do you understand? Eh, what? Reply, sir."

Arthur nodded. "I understand. And if Maunders hunts down The Spider he will be worth engaging as a partner."

"No, I don't mean that. But you are setting him to achieve an impossibility, and unless he fulfils your wish he cannot hope to be a partner. In the meantime, you and I hunt down The Spider. Then when we have him jailed, Maunders, not having done what you asked of him, can't expect to become a partner."
