Carruthers, or one of the maids--she were too tall for her ladyship--but
it warn't."

"Are you quite sure?" said Mr. Flexen.

"Quite, sir. I should have known 'er if she had been. Besides, she was
all muffled up like. You couldn't see 'er face."

"Did she hesitate before going through the library window?" said
Mr. Flexen.

"Not as I noticed. She seemed to go straight in."

"As if she were used to going into the Castle that way?" said Mr. Flexen.

William Roper scratched his head. Then he said cautiously: "She seemed to
know that way in all right, sir."

"And how was she dressed?" said Mr. Flexen.

"She wasn't in black. It wasn't as dull as black, but it was dullish. It
might have been grey and again it might not. It might have been blue or
brown. You see, there was a fair moon, sir, but it was be'ind the Castle,
an' I never seed 'er in the full moonlight, as you may say, seeing as,
coming and going, she come along the wall and went round the right 'and
corner of it, in the shadder."

"And which of these three people came away first?" said Mr. Flexen.

"She did. She wasn't in the Castle more nor twenty minutes--if that."
