Whilst they had been speaking, she had opened the door, a narrow iron one, well hung, for it opened easily and closed tightly without any creaking or sound of any kind. Within all was dark; but she entered as freely and with as little misgiving or restraint as if it had been broad daylight. For Adam, there was just sufficient green light from somewhere for him to see that there was a broad flight of heavy stone steps leading upward; but Lady Arabella, after shutting the door behind her, when it closed tightly without a clang, tripped up the steps lightly and swiftly. For an instant all was dark, but there came again the faint green light which enabled him to see the outlines of things. Another iron door, narrow like the first and fairly high, led into another large room, the walls of which were of massive stones, so closely joined together as to exhibit only one smooth surface. This presented the appearance of having at one time been polished. On the far side, also smooth like the walls, was the reverse of a wide, but not high, iron door. Here there was a little more light, for the high-up aperture over the door opened to the air.

Lady Arabella took from from her girdle another small key, which she inserted in a keyhole in the centre of a massive lock. The great bolt seemed wonderfully hung, for the moment the small key was turned, the bolts of the great lock moved noiselessly and the iron doors swung open. On the stone steps outside stood Oolanga, with the mongoose box slung over his shoulder. Lady Arabella stood a little on one side, and the African, accepting the movement as an invitation, entered in an obsequious way. The moment, however, that he was inside, he gave a quick look around him.

“Much death here—big death. Many deaths. Good, good!”

He sniffed round as if he was enjoying the scent. The matter and manner of his speech were so revolting that instinctively Adam’s hand wandered to his revolver, and, with his finger on the trigger, he rested satisfied that he was ready for any emergency.

There was certainly opportunity for the nigger’s enjoyment, for the open well-hole was almost under his nose, sending up such a stench as almost made Adam sick, though Lady Arabella seemed not to mind it at all. It was like nothing that Adam had ever met with. He compared it with all the noxious experiences he had ever had—the drainage of war hospitals, of slaughter-houses, the refuse of dissecting rooms. None of these was like it, though it had something of them all, with, added, the sourness of chemical waste and the poisonous effluvium of the bilge of a water-logged ship whereon a multitude of rats had been drowned.

Then, quite unexpectedly, the negro noticed the presence of a third person—Adam Salton! He pulled out a pistol and shot at him, happily missing. Adam was himself usually a quick shot, but this time his mind had been on something else and he was not ready. However, he was quick to carry out an intention, and he was not a coward. In another moment both men were in grips. Beside them was the dark well-hole, with that horrid effluvium stealing up from its mysterious depths.

With drooping heads and tremulous tails, they mashed their way through the thick mud, floundering and stumbling between whiles, as if they were falling to pieces at the larger joints. As often as the driver rested them and brought them to a stand, with a wary “Wo–ho! so–ho–then!” the near leader violently shook his head and everything upon it—like an unusually emphatic horse, denying that the coach could be got up the hill. Whenever the leader made this rattle, the passenger started, as a nervous passenger might, and was disturbed in mind.

There was a steaming mist in all the hollows, and it had roamed in its forlornness up the hill, like an evil spirit, seeking rest and finding none. A clammy and intensely cold mist, it made its slow way through the air in ripples that visibly followed and overspread one another, as the waves of an unwholesome sea might do. It was dense enough to shut out everything from the light of the coach–lamps but these its own workings, and a few yards of road; and the reek of the labouring horses steamed into it, as if they had made it all.

Two other passengers, besides the one, were plodding up the hill by the side of the mail. All three were wrapped to the cheekbones and over the ears, and wore jack–boots. Not one of the three could have said, from anything he saw, what either of the other two was like; and each was hidden under almost as many wrappers from the eyes of the mind, as from the eyes of the body, of his two companions. In those days, travellers were very shy of being confidential on a short notice, for anybody on the road might be a robber or in league with robbers. As to the latter, when every posting–house and ale–house could produce somebody in “the Captain’s” pay, ranging from the landlord to the lowest stable non–descript, it was the likeliest thing upon the cards. So the guard of the Dover mail thought to himself, that Friday night in November, one thousand seven hundred and seventy–five, lumbering up Shooter’s Hill, as he stood on his own particular perch behind the mail, beating his feet, and keeping an eye and a hand on the arm–chest before him, where a loaded blunderbuss lay at the top of six or eight loaded horse–pistols, deposited on a substratum of cutlass.

The Dover mail was in its usual genial position that the guard suspected the passengers, the passengers suspected one another and the guard, they all suspected everybody else, and the coachman was sure of nothing but the horses; as to which cattle he could with a clear conscience have taken his oath on the two Testaments that they were not fit for the journey.

“Wo–ho!” said the coachman. “So, then! One more pull and you’re at the top and be damned to you, for I have had trouble enough to get you to it!—Joe!”

“Halloa!” the guard replied.

“What o’clock do you make it, Joe?”

“Ten minutes, good, past eleven.”
