Character mistake: Clyde is a tortoise, but Joan, after finding Sherlock, put him in her bed, brings him down and calls him his "pet turtle." (00:14:08)

While You Were Sleeping - S1-E2
Other mistake: When Sherlock was slapped, he later says he was surprised because the girl who slapped him was a "lefty." Then he rubs his right cheek and says it's leathery from all the slaps he's gotten, while the left is soft. This is backwards - anyone hitting him with their right hand would hit his left cheek.
Sherlock Holmes: If you eliminate the impossible, whatever remains, however improbable, is the truth.
The Hound of the Cancer Cells - S2-E18
Trivia: "The Hound of the Cancer Cells" is a loose reference to "The Hound of the Baskervilles", perhaps the most famous of the four Sherlock Holmes novels.

Chosen answer: M broke into the brownstone and left a note. Holmes deduced he was staying at a high-class hotel from the soap scent on the note, and gave a picture from a hidden camera to his "irregulars" on the street to stake out hotels. One of them saw him, so Holmes followed him to his next intended victim and knocked him unconscious with a baton.
