As I said at the first, Mr. Detective,
she was found in the dress so selected
by the governess whose objective
was to fix the blighted thing.
Ms. Swan had mended it that very day
before our girl went off to play
and see her end when she did stray
within those deadly woods.

It was a very nice dress by the look of it in the papers. Not the sort one would think a young lady might go running off in the woods in. I couldn't tell you much beyond that, though.
