Do a lot of drugs Sherlock Holmes?
An AU where our ‘fantastic’ consulting detective isn’t as efficient as he lets onto be and conveniently gets himself addicted to cognitive enhancing drugs. Unfortunately, with success there is always failure. Slowly the sleuth’s brain starts to deteriorate to depend solely on these drugs, even to think out the most simplest of tasks.
John finally catches wind of this and gently tries to work him off the drugs but Sherlock Holmes during rehab is a violent and unpleasant experience.
