“Exactly. And have you not, in such a case, tried the word once or twice on the edge of the blotting-paper, or a spare scrap of paper, to see if it looked right? Well, that is what Mrs. Inglethorp did. You will notice that the word ‘possessed’ is spelt first with one ‘s’ and subsequently with two⁠—correctly. To make sure, she had further tried it in a sentence, thus: ‘I am possessed.’ Now, what did that tell me? It told me that Mrs. Inglethorp had been writing the word ‘possessed’ that afternoon, and, having the fragment of paper found in the grate fresh in my mind, the possibility of a will⁠—(a document almost certain to contain that word)⁠—occurred to me at once. This possibility was confirmed by a further circumstance. In the general confusion, the boudoir had not been swept that morning, and near the desk were several traces of brown mould and earth. The weather had been perfectly fine for some days, and no ordinary boots would have left such a heavy deposit.
