"What is it?"

"I shan't tell you or any man," snapped the ex-police commissioner. "It is sufficient to say that it is not a very bad secret, and that even if it were told to the world it would matter little. However, The Spider--hang him, I think he must have some acquaintance with my life in the East--has learned something I thought no one but myself knew anything about. He asks one thousand pounds, which is moderate compared with his demand on Emily. Shows that he knows my secret isn't so very deadly, or it would be worth more."

"Did he write to you?" asked Vernon alertly. "Of course he did, making the usual threat of exposure by postcards to self and friends. Now I am going to consent to his demands."

"And pay the money?"

"I didn't say that," corrected Dimsdale sharply, "but I am writing asking him to meet me in my library, and receive the money; also for him to hand over any documents to me which even hint at my secret. When he comes, you can be concealed in the room and we'll take him in charge."

"But then your secret will become known," objected Vernon. "The Spider always provides against arrest by leaving the evidence in the hands of others to publish."

"He can publish what he likes about me," said Mr. Dimsdale coolly; "don't I tell you that the secret is of little value. The Spider in his letter to me embroidered upon actual fact, and can make things unpleasant; but I can prove the exact truth of what he states, and so can save my bacon. There may be a few cold shoulders, but I shan't care for that, especially when my own conscience is clear. Now, don't ask me to tell you my secret, for I shan't. It has nothing to do with you or anyone else. All you have to do is to come to-morrow or the next day to my house at Hampstead, and I'll sketch out the plan of campaign."

"What about Mrs. Bedge?"

"She has a fortnight to consider the payment. We shall catch the scoundrel before then--you understand. Eh, what? Good! Now I must be off to Julia's ball. Are you coming?--not asked! Of course; you love Lucy, and that will never do for Julia, who wants her to make a titled match. Good-night! Ha, ha! You have plenty to think about. Don't get brain fever. Good night!"

Then the oddly-assorted pair parted for the time being.
