John,

If you have found this, something has happened between us that has proved so irreparable that you have made the decision to move out. You wouldn't have undone the bookshelf otherwise. I very much doubt that it is because of me, since I can convince you to stay with a deduction and a half. That's not important. Of time we have little, my dear Watson.

Seeing as you are reading this, you have either moved out because you believe yourself ridiculously in love with another person or something has happened to me, making me unable to stop you from leaving me. If I have somehow died, know that I am not dead. I am alive and well, and I can prove it. Mrs. Hudson of course is very well trained and under my eye at all times. When I passed, if she said "please don't leave, John. Don't leave me too." When you told her you were leaving, I am alive. If she offers to help you move my things out, I am well and truly dead. I am sorry for that. You can stop reading if I am dead and move on. I am so sorry.

However, I am glad you continued to read anyway. I have sources everywhere, John. My brother is the British government, and if I am alive based on the above criteria, I have kept in touch with him. I promise you, John, I am on my way back. Move all of your things back into 221B Baker Street. In exchange for this, I give you permission to throw away all things you find odd or weird in the fridge and kitchen. My experiments will have expired by now and clearly I do not have the ability to properly record what happened. Please clean it all out.

You must know that I care about you more than I ever have for any single organism in my entire life. When you call me fantastic or incredible, my stomach does bizarrely unscientific things. I have done much research on this and my hypothesis has proven correct, as always; I, Sherlock Holmes, am in love with you, John H. Watson. Just wait a little longer.

Text Mycroft and let him know you found this. He will give you a more specific idea of when I will be home to you. Please don't leave me, John. Don't leave us. I will return to you.
