Read the note Jackie received from her college roommate.

Dear Jackie,

I have left the house and I am staying with my parents for a while. I think I have figured out what is causing those strange squeaking noises in the middle of the night. I noticed this morning that there are holes in boxes of food in the cupboard. I also noticed that there are tiny paw prints next to the food boxes. I am afraid that our house has a mouse. Please call the superintendent and ask him to get rid of it. Hope to see you in a few days.

Maria
