is!"
"Put it into your pocket, Dyson," he said, after a pause. "I would not let any one have a glimpse of the thing, if I were you. I would not talk about it. Did either of the men you saw see you?"
"Well, I think not. I don't think the first man, the man who was vomited out of the dark passage, saw anything at all; and I am sure that the second could not have seen me."
"And you didn't really see them. You couldn't recognize either the one or the other if you met him in the street to-morrow?"
"No, I don't think I could. The street, as I said, was dimly lighted, and they ran like mad-men."
The two men sat silent for some time, each weaving his own fancies of the story; but lust of the marvellous was slowly overpowering Dyson's more sober thoughts.
"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."
Shortly afterwards Dyson took his leave, and Mr. Phillipps spent the rest of the night in examining some flint arrow-heads which he had purchased. He had every reason to believe that they were the work of a modern and not a palæolithic man, still he was far from gratified when a close scrutiny showed him that his suspicions were well founded. In his anger at the turpitude which would impose on an ethnologist, he completely forgot Dyson and the gold Tiberius; and when he went to bed at first sunlight, the whole tale had faded utterly from his thoughts.
The Encounter of the Pavement.
Mr. Dyson, walking leisurely along Oxford. Street, and staring with bland inquiry at whatever caught his attention, enjoyed in all its rare flavors the sensation that he was really very hard at work. His observation of mankind, the traffic, and the shop-windows tickled his faculties with an exquisite bouquet; he looked serious, as one looks on whom charges of weight and moment are laid, and he was attentive in his glances to right and left, for fear lest he should miss some circumstance of more acute significance. He had narrowly escaped being run over at a crossing by a charging van, for he hated to hurry his steps, and indeed the afternoon was warm; and he had just halted by a place of popular refreshment, when the astounding gestures of a well dressed individual on the opposite pavement held him enchanted and gasping like a fish. A treble line of hansoms, carriages, vans, cabs, and omnibuses, was tearing east and west, and not the most daring adventurer of the crossings would have cared to try his fortune; but the person who had attracted Dyson's attention seemed to rage on the very edge of the pavement, now and then darting forward at the hazard of instant death, and at each repulse absolutely dancing with excitement, to the rich amusement of the passers-by. At last, a gap that would, have tried the courage of a street-boy appeared between the serried lines of vehicles, and the man rushed across in a frenzy, and escaping by a hair's breadth pounced upon Dyson as a tiger pounces on her prey. "I saw you looking about you," he said, sputtering out his words in his intense eagerness; "would you mind telling me this? Was the man who came out of the Aerated Bread Shop and jumped, into the hansom three minutes ago a youngish looking man with dark whiskers and spectacles? Can't you speak, man? For Heaven's sake can't you speak? Answer me; it's a matter of life and death."
The words bubbled and boiled out of the man's mouth in the fury of his emotion, his face went from red to white, and the beads of sweat stood out on his forehead, and he stamped his feet as he spoke and tore with his hand at his coat, as if something swelled and choked him, stopping the passage of his breath.
"My dear sir," said Dyson, "I always like to be accurate. Your observation was perfectly correct. As you say, a youngish man, a man, I should say, of somewhat timid bearing, ran rapidly out of the shop here, and bounced into a hansom that must have been waiting for him, as it went eastwards at once. Your friend also wore spectacles, as you say. Perhaps you would like me to call a hansom for you to follow the gentleman?"
"No, thank you; it would be waste of time." The man gulped down something which appeared to rise in his throat, and Dyson was alarmed to see him shaking with hysterical laughter, and he clung hard to a lamp-post and swayed and staggered like a ship in a heavy gale.
"How shall I face the doctor?" he murmured to himself. "It is too hard to fail at the last moment." Then he seemed to recollect himself, and stood straight again, and looked quietly at Dyson. I owe you an apology for my violence, he said at last. "Many men would not be so patient as you have been. Would you mind adding to your kindness by walking with me a little way? I feel a little sick; I think it's the sun."
Dyson nodded assent, and devoted himself to a quiet scrutiny of this strange personage as they moved on together. The man was dressed in quiet taste, and the most scrupulous observer could find nothing amiss with the fashion or make of his clothes, yet, from his hat to his boots, everything seemed inappropriate. His silk hat, Dyson thought, should have been a high bowler of odious pattern worn with a baggy morning-coat, and an instinct told him that the fellow did not commonly carry a clean pocket-handkerchief. The face was not of the most agreeable pattern, and was in no way improved by a pair of bulbous chin-whiskers of a ginger hue, into which mustaches of light color merged imperceptibly. Yet in spite of these signals hung out by nature, Dyson felt that the individual beside him was something more than compact of vulgarity. He was struggling with himself, holding his feelings in check, but now and again passion would mount black to his face, and it was evidently by a supreme effort that he kept himself from raging like a madman. Dyson found something curious and a little terrible in the spectacle of an occult emotion thus striving for the mastery,
