Author's notes: A prequel of sorts to Someone Else's Day Off. A few people asked for the explanation of the throwaway line about Sherlock rescuing a tortoise. So, I've written this. It is very silly.

EDIT: It has come to my attention that my previous use of 'turtle' here was a Britpicking error on my part. All instances of turtle have now been replaced with 'tortoise'. Apologies for any confusion.

( Sherlock, tortoises did not evolve shells so they could be tossed. )
