Express post, First class; To: Gen. Thomas Jones, 5th Northumberland Fulsiliers:

General Jones, First, allow me to thank you for your efforts in helping to find my fiance, John Watson. I felt the need to write you, because if you do find him, I'd like for you to deliver the enclosed letter to him. Please, keep him safe as best you can. I know the job you do is difficult, and one soldier does not equal the lives of many, but.. please. Bring him home.

Signed,

Sherlock Holmes
