Sherlock is the master of deduction, a consulting detective, the only one in the world as he invented the job. He's brilliant, a proper genius, and doesn't he know it. Should you ever meet him, he will no doubt read your family history in your mobile phone and your occupation in the way you hold yourself. Be warned though, he is not a man who has time for social graces, so you may find him more than just a little insulting at times, but you mustn't be offended if he calls you an idiot, he thinks practically everyone is!
