5. The Vermeer Is A Fake

Vermeer Sherlock Fake
This deduction is on this list for a completely different reason. It is just completely random and no ‘normal’ person could ever solve it. This just underlies the brilliance of Sherlock Holmes. Sherlock is called in, as part of Moriarty’s game, to investigate a body that has washed up on the shore of the Thames. After a short investigation of the body Sherlock states that the lost Vermeer painting that has been found in London is a fake.
This deduction seems completely ridiculous as it is such a random conclusion to come to from the corpse of a, seemingly unrelated, dead man. However, once Sherlock explains it does begin to make sense. The man has ticket stubs in his pocket from the National Gallery. This tells Sherlock that he works there as he did not have full tickets. Sherlock knows of an assassin that has been in the area and this convinces him that the man had found out something that he shouldn’t have done.7
This is the opposite end of the spectrum as this deduction is far from simple. However, it is still equally brilliant and deserving of a place on this list.

4. The Queen Smokes

Queen Smokes
This is definitely one of the more zany deductions in Sherlock. In the first episode of the second series Sherlock and Watson are summoned to Buckingham Palace by Mycroft Holmes to aid in the acquisition of lost state secrets. Sherlock memorably refuses to dress as Mycroft will not tell him who the client is.
Even more memorable though, is the deduction that Sherlock carries out whilst sitting in the Palace. In short, the Queen smokes. He notices the ashtrays around the place and realises that the Queen’s chief of staff does not smoke. This leads him to deduce that it must be Her Majesty herself who has the smoking habit. This is certainly one of the more amusing Sherlock moments!

3. Irene Adler’s Safe Code

If there’s any woman who has ever got Sherlock hot under the collar then it is Irene Adler. You will remember Irene as the naked one from series two. She certainly knows how to make an entrance and she even succeeded in getting Sherlock a little smitten. But there was more to her nakedness than initially met the eye.
This was her way of giving Sherlock the code for her safe. As she told John before climbing out of the window, it was her measurements. This deduction is chosen, purely because it makes Sherlock seem almost human. He may be a sociopathic genius but he still notices the figure of a woman.
This is also true for Sherlock’s deduction, later in the episode, that Irene Adler was aroused by him and it wasn’t all for effect. This seems impossible to know but Sherlock reveals that he could read it via her pulse.

2. Major Barrymore’s Password

Hound
This deduction is significant just because it is something that we all wish we could do. We’ve all been there. Either you’re trying to log in to your friends Facebook in order to leave a rude message on their wall or you’re trying to crack their iPhone passcode to take funny pictures on their phone. We all wish we could crack the passwords of our friends.
In the series two episode, The Hound of Baskerville, Sherlock does exactly that. He needs the password of the head of the Baskerville research facility, Major Barrymore. He sits in his office, where he would have sat to think up his password, and looks around at eye level to find the key.
Several separate biographies of Margaret Thatcher later and Sherlock realises that the password could only be ‘Maggie’. This deduction qualifies for this list by virtue of being something we all wish we could do. It all seems so simple, if only it was that easy in real life!

1. Assessment Of The Jury

Sherlockjury
In the latest episode, The Reichenbach Fall, Jim Moriarty, Sherlock’s nemesis, is on trial for several high profile break ins. Due to his links with the defendant Sherlock is called in as an expert witness. What follows is a very funny scene in which Sherlock repeatedly chastises the barrister questioning him for asking leading questions and also analyses the entire jury.
This deduction makes this list as it perfectly showcases the slightly more sociopathic elements of Sherlock’s character. He is constantly told before the trial that he can’t show off and yet when it comes to it, he can’t help himself.
Of course, this time Sherlock misses the crucial deduction. That Moriarty has got to the jury first and threatened them all and their families. Sherlock fails to work this out and Moriarty walks free with a not guilty verdict. Only time will tell how Sherlock will eventually beat Moriarty and, somehow, rise from the dead. That will surely be his greatest deduction of all.
