Sherlock is assaulted by an unknown assailant while John is away at a medical conference, leaving him with a severe brain injury. While his intellect and personality are intact, he's lost the use of his right-side limbs and his ability to speak freely.

And Sherlock Holmes has never been the best of patients. (R)
