In His Last Bow, Sir Arthur Conan Doyle mentions that Holmes retired to a small farm on the Downs five miles from Eastbourne where he was “living the life of a hermit” among his bees and books. This would hardly be orange and lemon growing territory.
This was initially posted as a CIDU. Then, all at once, ZBicyclist realized it belonged on the OY page.
Fun with homonyms.
Comics I Don't Understand 
Let’s credit Vic Lee with a bit of finesse this time out. Even though the lemon tree gives the sound equivalent of the expected “Elementary”, it does not provide the rhetorical gesture this bit of dialogue serves for in the originals. HOWEVER, that gets taken care of by adding the “Duh!”
In The Strange Case of the End of the World as We Know It, a short TV movie from 1977, John Cleese as Holmes commits Lemon Tree and many other puns while answering crossword clue questions that Watson (Arthur Lowe) has.

Conan Doyle never cared what other authors did to his character Sherlock Holmes. When William Gillette put together a play based on Doyle’s work, he added a love interest for the detective. Gillette sent a cable, “May I marry Holmes?” Doyle replied “You may marry him, murder him, or do anything you like to him.” That was only the first of thousands of non-canonical Sherlock Holmes works. Even Creative Computing magazine in the 1970’s ran an original story in which Mycroft Holmes, who tends Babbage’s Analytical Engine which was secretly completed and made operational by Her Majesty’s government, uses the computer to assist Sherlock in uncovering a cheating scandal at a gaming club. Cyberpunk long before cyberpunk. Anyway, Sherlock Holmes most definitely did say “Elementary, my dear Watson,” even if not in any of the canonical works. I think it may have been Basil Rathbone in a movie. And if I remember correctly, in the Firesign Theatre’s “The Giant Rat of Sumatra” he says “Alimentary, my dear Watson” in reference to the eating habits of the giant rat or something. “The Giant Rat of Sumatra” by the way is the title of an adventure mentioned by Doyle but never published, very much like “the noodle incident” in Calvin and Hobbes.
The heirs of Conan Doyle were quite a different story. They were getting money for nothing, and didn’t want unauthorized (meaning non-paying) uses.
Is Mrs. Watson (nee Mary Marston) with them also?
I know have a seen a production about Holmes – I believe it was a Broadway play – where he meets a woman and at the end when she talks of marriage he says that he cannot inflict his addiction on her – she says it does not matter and pulls out her pipe – they hug, kiss and the curtain falls. (How many decades ago this was, I have no idea.)
