I turned out of one of the nominally empty houses, where I had gone to lodge with a still humbler servant of the Estate, and went down to No. 7 with some hope that its mistress at all events might already have retired. Almost to my horror I learned that they were all three in the back garden, whither I was again conducted through the little dining-room with the massive furniture.
Mrs. Delavoye was a fragile woman with a kind but nervous manner; the daughter put me more at my ease, but I could scarcely see either of them by the dim light from the French window outside which they sat. I was more eager, however, to see "the pit's mouth," and in the soft starlight of a velvet night I made out the two Dutch chairs lying face downward over the shaft.
"It's so tiresome of my brother," said Miss Delavoye, following my glance with disconcerting celerity: "just when we want our garden chairs he's varnished them, and there they lie unfit to use!"
I never had any difficulty in looking stolid, but for the moment I avoided the impostor's eyes. It was trying enough to hear his impudent defence.
"You've been at me about them all the summer, Amy, and I felt we were in for a spell of real hot weather at last."
"I can't think why you've put them out there, Uvo," remarked his mother. "They won't dry any better in the dew, my dear boy."
"They won't make a hopeless mess of the grass, at all events!" he retorted. "But why varnish our dirty chairs in public? Mr. Gillon won't be edified; he'd much rather listen to the nightingale, I'm sure."
Had they a nightingale? I had never heard one in my life. I was obliged to say something, and this happened to be the truth; it led to a little interchange about Scotland, in which the man Uvo assumed a Johnsonian pose, as though he had known me as long as I felt I had known him, and then prayed silence for the nightingale as if the suburban garden were a banqueting hall. It was a concert hall, at any rate, and never was sweeter solo than the invisible singer poured forth from the black and jagged wood between glimmering lawn and starry sky. I see the picture now, with the seated ladies dimly silhouetted against the French windows, and our two cigarettes waxing and waning like revolving lights seen leagues away. I hear the deep magic of those heavenly notes, as I was to hear them more summers than one from that wild wood within a few yards of our raw red bricks and mortar. It may be as the prelude of what was to follow that I recall it all so clearly, down to the couplet that Uvo could not quite remember and his sister did:
"The voice I hear this passing night was heard
In ancient days by emperor and clown."
"That's what I meant!" he cried. "By emperor, clown, and old man Mulcaster in his cups! Think of him carrying on in there to such a tune, and think of pious Christopher holding family prayers to it now!"
And the bare thought dashed from my lips a magic potion compounded of milky lawn and ebony horse-chestnuts, of an amethyst sky twinkling with precious stars, and the low voice of a girl trying not to drown the one in the wood; the spell was broken, and I was glad when at last we had the garden to ourselves.
"There are two things I must tell you for your comfort," said the incorrigible Uvo as we lifted one Dutch chair from the hole it covered like a hatchway, but left the other pressed down over the heap of earth. "In the first place, both my mother and sister have front rooms, so they won't hear or bother about us again. The other thing's only that I've been back to the Free Library in what the simple inhabitants still insist on calling the Village, and had another look into those annals of old Witching Hill. I can find no mention whatever of any subterranean passage. I shouldn't wonder if good Sir Chris had never heard of it in his life. In that case we shall rush in where neither man nor beast has trodden for a hundred and fifty years."
We lit our candles down the shaft, and then I drew the Dutch chair over the hole again on Delavoye's suggestion; he was certainly full of resource, and I was only too glad to play the practical man with my reach and strength. If he had been less impetuous and headstrong, we should have made a strong pair of adventurers. In the tunnel he would go first, for instance, much against my wish; but, as he put it, if the foul air knocked him down I could carry him out under one arm, whereas he would have to leave me to die in my tracks. So he chattered as we crept on and on, flinging monstrous shadows into the arch behind us, and lighting up every patch of filth ahead; for the long-drawn vault was bearded with stalactites of crusted slime; but no living creature fled before us; we alone breathed the impure air, encouraged by our candles, which lit us far beyond the place where my match had been extinguished and deeper and deeper yet without a flicker.
Then in the same second they both went out, at a point where the overhead excrescences made it difficult to stand upright. And there we were, like motes in a tube of lamp-black; for it was a darkness as palpable as fog. But my leader had a reassuring explanation on the tip of his sanguine tongue.
"It's because we stooped down," said he. "Strike a match on the roof if it's dry enough. There! What did I tell you? The dregs of the air settle down like other dregs. Hold on a bit! I believe we're under the house, and that's why the arch is dry."
We continued our advance with instinctive stealth, now blackening the roof with our candles as we went, and soon and sure enough the old tube ended in a wad of brick and timber.
In the brickwork was a recessed square, shrouded in cobwebs which perished at a sweep of Delavoye's candle; a wooden shutter closed the aperture, and I had just a glimpse of an oval knob, green with verdigris, when my companion gave it a twist and the shutter sprang open at the base. I held it up while he crept through with his candle, and then I followed him with mine into the queerest chamber I had ever seen.
It was some fifteen feet square, with a rough parquet floor and panelled walls and ceiling. All the woodwork seemed to me old oak, and reflected our naked lights on every side in a way that bespoke attention; and there was a tell-tale set of folding steps under an ominous square in the ceiling, but no visible break in the four walls, nor yet another piece of movable furniture. In one corner, however, stood a great stack of cigar boxes whose agreeable aroma was musk and frankincense after the penetrating humours of the tunnel. This much we had noted when we made our first startling discovery. The panel by which we had entered had shut again behind us; the noise it must have made had escaped us in our excitement; there was nothing to show which panel it had been—no semblance of a knob on this side—and soon we were not even agreed as to the wall.
Uvo Delavoye had enough to say at most moments, but now he was a man of action only, and I copied his proceedings without a word. Panel after panel he rapped and sounded like any doctor, even through his fingers to make less noise! I took the next wall, and it was I who first detected a hollow note. I whispered my suspicion; he joined me, and was convinced; so there we stood cheek by jowl, each with a guttering candle in one hand, while the other felt the panel and pressed the knots. And a knot it was that yielded under my companion's thumb. But the panel that opened inwards was not our panel at all; instead of our earthy tunnel, we looked into a shallow cupboard, with a little old dirty bundle lying alone in the dust of ages. Delavoye picked it up gingerly, but at once I saw him weighing his handful in surprise, and with one accord we sat down to examine it, sticking our candles on the floor between us in their own grease.
"Lace," muttered Uvo, "and something in it."
The outer folds came to shreds in his fingers; a little deeper the lace grew firmer, and presently he was paying it out to me in fragile hanks. I believe it was a single flounce, though yards in length. Delavoye afterwards looked up the subject, characteristically, and declared it Point de Venise; from what I can remember of its exquisite workmanship, in monogram, coronet, and imperial emblems, I can believe with him that the diamond buckle to which he came at last was less precious than its wrapping. But by that time we were not thinking of their value; we were screwing up our faces over a dark coagulation which caused the last yard or so to break off in bits.
"Lace and blood and diamonds!" said Delavoye, bending over the relics in grim absorption. "Could the priceless old sinner have left us a more delightful legacy?"
"What are you going to do with them?" I asked rather nervously at that. They had not been left to us. They ought surely to be delivered to their rightful owner.
"But
