he said quietly. "They have bolted us in and apparently set fire to the place."
We did not require much urging to act quickly. Picking up one of the long, ponderous iron cylinders, we ran with it along the passage towards the light of Thorndyke's lamp. As we ascended the steps I became plainly aware of the smell of burning wood and of a crackling sound, faintly audible through the massive door. "There is only one bolt," said Thorndyke; "I noticed it as we came in. I will throw my light on the part of the door where it is fixed, and you two must batter on that spot with the cylinder."
The door was, as I have said, a massive one, but it would have been a massive door indeed that could have withstood the blows of that ponderous iron cylinder, wielded by two strong men whose lives depended on their efforts. At the very first crash of the battering-ram, a tiny chink opened and at each thundering blow, the building shook. Furiously we pounded at the thick, plank-built door, and slowly the chink widened as the screws of the bolt tore out of the woodwork. And as the chink opened, a thin reek of pungent smoke filtered in, and the cold light of Thorndyke's lantern became contrasted with a red glare from without. And then suddenly, the door, under the heavy battering, burst from its fastenings and swung open. A blinding, choking cloud of smoke and sparks rolled in upon us, through which we could see in the corridor outside a pile of straw and crates and broken packing-cases, blazing and cracking furiously. It looked as if we were cut off beyond all hope.
Jervis and I had dropped the now useless cylinder and were gazing in horror at the blazing mass that filled the corridor and cut off our only means of escape, when we were recalled by the voice of Thorndyke, speaking in his usual quiet and precise manner. "We must get the full cylinders up as quickly as possible," said he; and, running down the steps he made straight for the end cellar, whither we followed him. Picking up one of the cylinders, we carried it quickly to the top of the steps. "Lay it down," said Thorndyke, "and fetch another."
Jervis and I ran back to the cellar, and taking up another cylinder, brought it along the passage. As we were ascending the steps, there suddenly arose a loud, penetrating hiss, and as we reached the top, we saw Thorndyke disengaging the spanner from the cock of the cylinder out of which a jet of liquid was issuing, mingled with a dense, snowy cloud.
An instantaneous glance, as we laid down the fresh cylinder, reassured me very considerably. The icy, volatile liquid and the falling cloud of intensely cold carbonic acid snow had produced an immediate effect; as was evident in a blackened, smouldering patch in the midst of the blazing mass. With reviving hope I followed Jervis once more down the steps and along the passage to the end cellar, from which we brought forth a third cylinder.
By this time the passage was so filled with smoke that it was difficult either to see or to breathe, and the bright light that had at first poured in through the open doorway had already pulled down so far that Thorndyke's figure, framed in the opening, loomed dim and shadowy amidst the smoke and against the dusky red background. We found him, when we reached the top of the steps, holding the great gas bottle and directing the stream of snow and liquid on to those parts of the wood and straw from which flames still issued. "It will be all right," he said in his calm, unemotional way; "the fire had not really got an effective start. The straw made a great show, but that is nearly all burnt now, and all this carbonic acid gas will soon smother the burning wood. But we must be careful that it doesn't smother us too. The steps will be the safest place for the present."
He opened the cock of the new cylinder and, having placed it so that it played on the most refractory part of the burning mass, backed to the steps where Jervis and I stood looking through the doorway. The fire was, as he has said, rapidly dying down. The volumes of gas produced by the evaporation of the liquid and the melting snow, cut off the supply of air so that, in place of the flames that had, at first, looked so alarming, only a dense reek of smoke arose. "Now," said Thorndyke, after we had waited on the steps a couple of minutes more, "I think we might make a sortie and put an end to it. If we can get the smouldering stuff off that wooden floor down on to the stone, the danger will be over."
He led the way cautiously into the corridor, and, once more bringing his electric lamp into requisition, began to kick the smouldering cases and crates and the blackened masses of straw down the steps on to the stone floor of the passage, whither we followed them and scattered them with our feet until they were completely safe from any chance of re-ignition. "There," said Jervis, giving a final kick at a small heap of smoking straw, "I should think that ought to do. There's no fear of that stuff lighting up again. And, if I may venture to make the remark, the sooner we are off these premises the happier I shall be. Our friend's methods of entertaining his visitors are a trine too strenuous for my taste. He might try dynamite next."
"Yes," I agreed; "or he might take pot shots at us with a revolver from some dark corner."
"It is much more likely," said Thorndyke, "that he has cleared off in anticipation of the alarm of fire. Still, it is undeniable that we shall be safer outside. Shall I go first and show you a light?"
He piloted us along the corridor and up the cobbled yard, putting away his lamp as he unlocked the wicket. There was no sign of anyone about the premises nor, when we had passed out of the gate, was there anyone in sight in the street. I looked about, expecting to see some sign of the fire; but there was no smoke visible, and only a slight smell of burning wood. The smoke must have drifted out at the back. "Well," Thorndyke remarked, "it has been quite an exciting little episode. And a highly satisfactory finish, as things turned out; though it might easily have been very much the reverse. But for the fortunate chance of those gas-bottles being available, I don't think we should be alive at this moment."
"No," agreed Jervis. "We should be in much the same condition by this time as Batson's late patient, Mr. Maddock, or at least, well on our way to that disembodied state. However, all's well that ends well. Are you coming our way, Jardine?"
"I will walk a little way with you," said I. "Then I must go back to Batson to settle up and fetch my traps."
I walked with them to Oxford Street and we discussed our late adventure as we went. "It was a pretty strong hint to clear out, wasn't it?" Jervis remarked.
"Yes," replied Thorndyke; "it didn't leave us much option. But the affair can't be left at this. I shall have a watch set on those premises, and I shall make some more particular enquiries about Mr. Gill. By the way, Jardine, I haven't your address. I'd better have it in case I want to communicate with you; and you'd better have my card in case anything turns up which you think I ought to know."
We accordingly exchanged cards, and, as we had now reached the corner of Oxford Street, I wished my friends adieu and thoughtfully retraced my steps to Jacob Street.
VIII. It's an Ill Wind—
London is a wonderful place. From the urban greyness of Jacob Street to the borders of Hampstead Heath was, even in those days of the slow horse tram, but a matter of minutes—a good many minutes, perhaps, but still, considerably under an hour. Yet, in that brief and leisurely journey, one exchanged the grim sordidness of a most unlovely street for the solitude and sweet rusticity of open and charming country.
A day or two after my second adventure in the mineral water works, I was leaning on the parapet of the viaduct—the handsome, red brick viaduct with which some builder, unknown to me, had spanned the pond beyond the Upper Heath, apparently with purely decorative motive, and in a spirit of sheer philanthropy. For no road seemed to lead anywhere in particular over it, and there was no reason why any wayfarer should wish to cross the pond rather than walk round it; indeed, in those days it was covered by a turfy expanse seldom trodden by any feet but those of the sheep that grazed in the meadows bordering
