French window through which Delavoye had disappeared. His wild idea had seemed to me the unwholesome fruit of a morbid imagination, but now I prepared to find it hateful fact. Down I went on my haunches, and groped with my hands in the mould, to learn the worst with least delay. The spade I had left sticking in the rotten wood, and now I ran reluctant fingers down its cold iron into the earth-warm splinters. They were at the extreme edge of the shaft that I was sinking, but I discovered more splinters at the same level on the opposite side. These were not of my making; neither were they part of any coffin, but rather of some buried floor or staging. My heart danced as I seized the spade again. I dug another foot quickly; that brought me to detached pieces of rotten wood of the same thickness as the jagged edges above; evidently a flooring of some kind had fallen in--but fallen upon what? Once more the spade struck wood, but sound wood this time. The last foot of earth was soon taken out, and an oblong trap-door disclosed, with a rusty ring-bolt at one end.I tugged at the ring-bolt without stopping to think; but the trap-door would not budge. Then I got out of the hole for a pickaxe that Delavoye had produced with the spade, and with one point of the pick through the ring I was able to get a little leverage. It was more difficult to insert the spade where the old timbers had started, while still keeping them apart, but this once done I could ply both implements together. There was no key-hole to the trap, only the time-eaten ring and a pair of hinges like prison bars; it could but be bolted underneath; and yet how those old bolts and that wood of ages clung together! It was only by getting the pick into the gap made by the spade, and prizing with each in turn and both at once, that I eventually achieved my purpose. I heard the bolt tinkle on hard ground beneath, and next moment saw it lying at the bottom of a round bricked hole. All this must have occupied far fewer minutes than it has taken to describe; for Delavoye had not returned to peer with me into a well which could never have been meant for water. It had neither the width nor the depth of ordinary wells; an old ladder stood against one side, and on the other the high sun shone clean down into the mouth of a palpable tunnel. It opened in the direction of the horse-chestnuts, and I was in it next moment. The air was intolerably stale without being actually foul; a match burnt well enough to reveal a horseshoe passage down which a man of medium stature might have walked upright. It was bricked like the well, and spattered with some repulsive growth that gave me a clammy daub before I realized the dimensions. I had struck a second match on my
