That woman was no other than Grace Poole.
There she sat, staid and taciturn-looking, as usual, in her brown stuff gown, her check apron, white handkerchief, and cap.

She was intent on her work, in which her whole thoughts seemed absorbed: on her hard forehead, and in her commonplace features, was nothing either of the paleness or desperation one would have expected to see marking the countenance of a woman who had attempted murder, and whose intended victim had followed her last night to her lair, and (as I believed), charged her with the crime she wished to perpetrate.

I was amazed--confounded.

She looked up, while I still gazed at her: no start, no increase or failure of colour betrayed emotion, consciousness of guilt, or fear of detection.

She said "Good morning, Miss," in her usual phlegmatic and brief manner; and taking up another ring and more tape, went on with her sewing.
"I will put her to some test," thought I: "such absolute impenetrability is past comprehension." "Good morning, Grace," I said.
