"Come and look at the thing," I said, and led the way to where the dummy
lay, its armored upper limbs all splayed adrift in queer contortions. I
stooped over it and pointed. There, driven right through the thick steel
breastplate, was the 'waeful dagger.'

"Good God!" said young Jarnock again. "Good God! It's the dagger! The
thing's been stabbed, same as Bellett!"

"Yes," I replied, and saw him glance swiftly toward the entrance of
the Chapel. But I will do him the justice to say that he never
budged an inch.

"Come and see how it was done," I said, and led the way back to the
chancel rail. From the wall to the left of the altar I took down a long,
curiously ornamented, iron instrument, not unlike a short spear. The
sharp end of this I inserted in a hole in the left-hand gatepost of the
chancel gateway. I lifted hard, and a section of the post, from the floor
upward, bent inward toward the altar, as though hinged at the bottom.
Down it went, leaving the remaining part of the post standing. As I bent
the movable portion lower there came a quick click and a section of the
floor slid to one side, showing a long, shallow cavity, sufficient to
enclose the post. I put my weight to the lever and hove the post down
into the niche. Immediately there was a sharp clang, as some catch

I went over now to the dummy, and after a few minute's work managed to
wrench the dagger loose out of the armor. I brought the old weapon and
placed its hilt in a hole near the top of the post where it fitted
loosely, the point upward. After that I went again to the lever and gave
