I had forgotten the details, but my hope was that the second was among the barrels.

I shut the outer door, prised up the trap, and dropped into the vault, which had been floored roughly with green bricks.

Lighting match after match, I crawled to the other end and tried to lift the door.

It would not stir, so I guessed that the barrels were on the top of it.

Back to the outhouse I went, and found that sure enough a heavy packing-case was standing on a corner.
