If Sherlock went to Hogwarts- well the title says it all really. Sherlock's family keep Hogwarts a secret as they believe him to be a Squib (someone born in a magical family but does not have Magic themselves) and when he gets his letter his life is turned around. Thinking maybe his huge intellect is due to him not being a muggle, he gets a shock as he enters the life of Hogwarts where once again he it surrounded by goldfish- admittedly magical goldfish- (who are just had a strange image there? ...sorry)- Here he meets his best friend John Watson and goes through normal teenage struggles- and if you think Hogwarts doesn't have a few puzzles to solve you'd be very wrong indeed.
