John,

I'm afraid this is my note. I'm not coming back this time. This time, there is no trickery or hiding or leaving you in the dark. You believed me dead once, believe me dead again. You will have Mary and the baby and God save you, Mycroft. Make sure he reads this too, I want him to know that it is not his fault and he should not blame himself for the manner of my death. These drugs were procured easily and it did not take long for them to kill me so please do not fret. It was not painless; I will not lie to you but it wasn't as bad as you think. I've dealt with much more pain caused by drugs however and this time, I made sure it was enough to kill me before it got to be too bad. This is my note and my final good bye John. A brilliant mind eventually grows sick of being alone and after years of shutting everyone but you and Lestrade out, I finally grew lonely again. You were a great friend to me John and I shall never forget you in the afterlife. Look after the Yard, Mrs. Hudson, and Mycroft for me, will you? John Hamish Watson I suppose, if this is my last chance to say this I…

Love the High Functioning Sociopathic man you call a best friend,
