"It is all more strange than I fancied," he said at last. "It was queer enough what I saw; a man is sauntering along a quiet, sober, every-day London street, a street of gray houses and blank walls, and there, for a moment, a veil seems drawn aside, and the very fume of the pit steams up through the flagstones, the ground glows, red hot, beneath his feet, and he seems to hear the hiss of the infernal caldron. A man flying in mad terror for his life, and furious hate pressing hot on his steps with knife drawn ready; here indeed is horror. But what is all that to what you have told me? I tell you, Phillipps, I see the plot thicken, our steps will henceforth be dogged with mystery, and the most ordinary incidents will teem with significance. You may stand out against it, and shut your eyes, but they will be forced open; mark my words, you will have to yield to the inevitable. A clue, tangled if you like, has been placed by chance in our hands; it will be our business to follow it up. As for the guilty person or persons in this strange case, they will be unable to escape us, our nets will be spread far and wide over this great city, and suddenly, in the streets and places of public resort, we shall in some way or other be made aware that we are in touch with the unknown criminal. Indeed, I almost fancy I see him slowly approaching this quiet square of yours; he is loitering at street corners, wandering, apparently without aim, down far-reaching thoroughfares, but all the while coming nearer and nearer, drawn by an irresistible magnetism, as ships were drawn to the Loadstone Rock in the Eastern tale." "I certainly think," replied Phillipps, "that, if you pull out that coin and flourish it under people's noses as you are doing at the present moment, you will very probably find yourself in touch with the criminal, or a criminal. You will undoubtedly be robbed with violence. Otherwise, I see no reason why either of us should be troubled. No one saw you secure the coin, and no one knows you have it. I, for my part, shall sleep peacefully, and go about my business with a sense of security and a firm dependence on the natural order of things. The events of the evening, the adventure in the street, have been odd, I grant you, but I resolutely decline to have any more to do with the matter, and, if necessary, I shall consult the police. I will not be enslaved by a gold Tiberius, even though it swims into my ken in a manner which is somewhat melodramatic." "And I for my part," said Dyson, "go forth like a knight-errant in search of adventure. Not that I shall need to seek; rather adventure will seek me; I shall be like a spider in the midst of his web, responsive to every movement, and ever on the alert."
