When I put all this together last night, remembering that Carr, by Middleton's own account, was the only person aware that he had jewels of great value in his keeping, I felt absolutely certain (as I feel still) that he had accepted the invitation, and come down from London solely for the purpose of stealing them.

It was pure conjecture on my part, and I dared say nothing beyond begging Ralph not to leave the jewels in the library--which, however, he did.

I went straight off to my room when the others went to smoke, but I did not go to bed.

The more I thought it over the more certain I felt that Carr would not let slip such an opportunity, the more convinced that an attempt would be made that very night.

I did not know that he was not sleeping in the house, but I knew Ralph was at the lodge, so I could not go and consult with him, as I should otherwise have done.
