Isn't it lovely to know that even the great Sherlock Holmes, the quirky and genius Sherlock Holmes, is vulnerable to love as we all are?

I imagine John Watson thinks love’s a mystery to me, but the chemistry is incredibly simple and very destructive. When we first met, you told me that a disguise is always a self portrait, how true of you, the combination to your safe – your measurements. But this is far more intimate. This is your heart, and you should never let it rule your head. You could have chosen any random number and walked out of here today with everything you worked for. But you just couldn’t resist it, could you? I’ve always assumed that love is a dangerous disadvantage. Thank you for the final proof.

No man burdens his mind with small matters unless he has some very good reason for doing so.

To a great mind, nothing is little,' remarked Holmes, sententiously.

Crime is common. Logic is rare. Therefore it is upon the logic rather than upon the crime that you should dwell.

Education never ends, Watson. It is a series of lessons, with the greatest for the last.
