And there is a beautiful card with a picture of Sherlock Holmes on it, and inside it reads.

One this very important day, I do hope you have a wonderful Brithday, my dear other self. Congradulations on making it another year, and keep up the good work. Criminals always need to be caught.

Yours truly 

Hakuba Saguru.
