How could my hair have been locked in the drawer?
With trembling hands I undid my trunk, turned out the contents, and drew from the bottom my own hair.

I laid the two tresses together, and I assure you that they were identical.

Was it not extraordinary?
Puzzle as I would, I could make nothing at all of what it meant.

I returned the strange hair to the drawer, and I said nothing of the matter to the Rucastles as I felt that I had put myself in the wrong by opening a drawer which they had locked.
"I am naturally observant, as you may have remarked, Mr.Holmes, and I soon had a pretty good plan of the whole house in my head.
There was one wing, however, which appeared not to be inhabited at all.

A door which faced that which led into the quarters of the Tollers opened into this suite, but it was invariably locked.
One day, however, as I ascended the stair, I met Mr.Rucastle coming out through this door, his keys in his hand, and a look on his face which made him a very different person to the round, jovial man to whom I was accustomed.
