Week 24: Miss Hudson in the English Room with a Purple Pen

So I walked into Miss Hudson's 8th hour class (her favorite) for well you know my class and she was distraught, I asked what was wrong and she had told me that her prized purple pen was purloined. (he he word play) So I asked her where she saw it last and she told me that she had it on Tuesday and she left it on her desk when she left to use the restroom. The problem is that when she came back, it was gone and there was a room full of students. The question was, who did it? She then hired me as her P.I. and so I started asking who was all in the room at the time and who was at the desk while she was gone. The problem with that is that everyone was in their own conversation and talking louder than the others so I couldn't get any good answers. But I finally was told that Kaleb, Timothy and Willie were up at the desk at the time...... Just what I feared. So I talked to them outside of the class and they all blamed each other. Luckily Willie told me that Timothy took it. So using my detective skills I told Timothy that Kaleb ratted him out and that got Timothy to blame Kaleb. Just what I expected. So I let them go at it and it turns out that neither of them took. Miss Hudson told us to stop arguing because she found the pen. It turns out that it was UNDER HER UNGRADED PAPERS!
