Conclusion
Back at Baker Street, Sherlock and John compare both versions of the story. Hyacinth has her version and Benedict has his. Some parts coincide and others are off. They deduce that Benedict's is probably the more accurate version because knowing the type of woman Hyacinth Bucket is, she would never admit to being wrong.
"So what did you think?" asks John.
"About what specifically?" asks Sherlock.
"Benedict…I think he could see the similarities in both of you and the way you both look like each other."
"I didn't get that at all," says Sherlock.
"OK, then what about the stories?"
"For the most part they do coincide…but each one makes the one who told it look like the innocent victim of the other."
"Yes, and that should make you feel better that Mrs. Hudson is not in any danger from this narcissistic woman we have come to know as Hyacinth Bucket," assured John.
"I do feel much better," Sherlock interjects, "I was thinking of contacting Mrs. Cumberbatch, aka Wanda Ventham, but the more I think about it the more I feel we would not learn anything new from her."
"Is that because there isn't anything new to learn or because you are afraid you might have to admit that your father is right?" inquires John.
Sherlock mumbles something under his breath, "It's because there isn't anything new to learn, John, and not the later reason."
"So in conclusion, Mrs. Hudson is not in any danger when around Hyacinth Bucket, and Hyacinth felt she recognized you simply because you looked like the actor, Benedict Cumberbatch, whom she had some dealings with at the Chelsea Flower show this past summer. And that was what the worried look, that caused you concern, was all about."
"That's it in a nutshell, John. Very good!"
"Then 'case closed', right Sherlock?"
"Yes, John, case closed."
John pulls out his computer to blog about it but changes his mind to protect the reputations of those involved with sealed police records, so he reads the papers instead, and Sherlock takes a long hard look at the picture that John took of him and Benedict this afternoon, reluctantly coming to the conclusion that maybe he and Benedict Cumberbatch do indeed look a bit alike. But that is one conclusion Sherlock will never admit to anyone.
