June 1st:
Harry,
I am owling this letter to you before your holiday in hopes that you will receive it before you leave for the Dursleys'. The Order has informed me that they will be moving their location from our previous headquarters to another building. Therefore, Harry, I would very much appreciate it if you could merely address your letters to Mr. Weasley's home. If you write your godfather's address on a letter, it will not get to us.
Also, I caution you with the content of your letters. Too much information can be a horrible thing.
Until next year,
Albus Dumbledore
Well, you all asked for it! Here's a little clue about the mishap. Your next clue is in the next chapter.
