“Again; Jeffrey had to be brought from Kennington to the inn by John. But John was personating Jeffrey and was made up to resemble him very closely. If Jeffrey were undisguised the two men would be almost exactly alike; which would be very noticeable in any case and suspicious after the death of one of them. Therefore Jeffrey would have to be disguised in some way; and what disguise could be simpler and more effective than the one that I suggest was used?

“Again; it was unavoidable that someone⁠—the cabman⁠—should know that Jeffrey was not alone when he came to the inn that night. If the fact had leaked out and it had become known that a man had accompanied him to his chambers, some suspicion might have arisen, and that suspicion would have pointed to John, who was directly interested in his brother’s death. But if it had transpired that Jeffrey was accompanied by a woman, there would have been less suspicion, and that suspicion would not have pointed to John Blackmore.
