The one thing he said which struck me as worth listening to, was this--that Miss Verinder had declined to be questioned by him, and had spoken to him with a perfectly incomprehensible rudeness and contempt.
I thought this curious--but I attributed it mainly to some clumsiness on the Superintendent's part which might have offended the young lady.

It ended, as you are aware, in the discovery of the smear on the door, and in Mr.Franklin Blake's evidence satisfying me, that this same smear, and the loss of the Diamond, were pieces of the same puzzle.

So far, if I suspected anything, I suspected that the Moonstone had been stolen, and that one of the servants might prove to be the thief.
