Order Only—Accusations

I notice that none of you have seen fit to come to my defence. I also find it curious that no-one seems to wonder how Minerva—also a spy at Hogwarts, and indeed the mistress of this place—would not know of shady dealings within the castle. Proof, I think, that personal dislikes are at play here: even Mr Black understands that it is impossible to track the activities of every one of the hundreds of people here. At least without using some of his more dangerous toys.

As for what I was doing last night, Professor Sprout shall confirm that I was helping her harvest flowers from the Night-Blooming Flitterweed until three o'clock in the morning. I then patrolled the castle—teachers usually refuse to take the shift between three o'clock and six o'clock in the morning, leaving me short on sleep—and returned to my quarters exhausted. I did not discover that the ring of master keys was missing from its hook until the morning; whoever it was reset my wards cleverly enough, though not seamlessly.

The person in question discovered my password, apparently—although fortunately not the password to my inner quarters. There are several women who have had the opportunity to learn the outer password in the past week. They are

Professor Acton
Madam Hooch
Hermione Granger
Professor Sinistra
Professor Sprout

I trust that Miss Granger and Professor Sprout do not seem suspicious to you, my dear canine? Or do you believe that through association I have corrupted them? 

I am disgusted with all of you.
