"Am I not laying a trap into which he will walk?" inquired Dimsdale with much exasperation. "Of course I fight, as my secret is not such a very bad one. I can defend myself, and I am willing to risk that being known which I had rather were kept silent, for the sake of saving other people from being blackmailed by the beast. Eh, what? Am I not right?" "Yes, I think you are. But I wish you would tell me your secret." "After we have captured this scamp I shall do so, and then I shall tell you the absolute truth together with his embroideries. Don't look so grave, boy. I haven't committed a murder or stolen from the till." "I never thought of such a thing," said Vernon hastily, "but----" Dimsdale good-humouredly pushed him towards the window. "I know your doubts, my boy, but later I can satisfy them. Meanwhile let us settle that I am a scoundrel, and look on this trap as one set by a thief to catch a thief. By the way, does Maunders know of the threat made by The Spider against his mother. She intended to tell him, you know." "I am not aware, sir. Maunders has not been near me since that night at the Athenian Club--the same night when I met you at Towton's rooms. Well, I shall come to the ball. Meantime, let me know----" "I'll advise you if I hear from The Spider. There, get out. Good-bye, unless you'll have a cup of tea or a glass of wine." Vernon declined and departed. The girls were no longer on the verandah or even in the garden. CHAPTER IV. WHO WAS CAUGHT IN THE TRAP. Vernon had his doubts as to the success of Mr. Dimsdale's scheme. The Spider, as the authorities very well knew, was a wary individual, and in all dealings with his victims had been careful to provide for his own safety. He certainly met them at duly-appointed places, disguised as an old woman or a young man, as a navvy or as a foreigner; but none of those he intimidated dared to call in the police. The reason was that The Spider invariably advised them beforehand by letter that his accomplice held the evidence of the secrets for which they were being blackmailed, and that any proceedings being taken would result in the publication of these by cards being sent to their friends and relatives and acquaintances. It therefore can easily be guessed that no one had the courage to lay the rogue by the heels.
