Purple Pen Mystery

The worst part about this mystery is that everyone thinks it was me because I am always using a purple pen. But I assure everyone that it was not me. I did see a shady character dressed in all black in Hudson's classroom though earlier yesterday. He/she was snooping through her desk, I just walked away because I did not think anything of it at the moment. I do not know who the person was but I do believe that they took the pen. I would just look for someone else who uses a purple pen in the next few days.
