I Think the New Kid is a Secret Agent!

There's a new girl in my class, and I'm convinced she's a SECRET AGENT! She wears two earpieces - just like the spies in my favorite book, Spies in Space! How exciting is that?
Every day, she reports to someone - a handler from the D.E.A.P! I have no idea what that stands for, but it has to be something super-duper SECRET! I need to find out what she's really up to.
Good thing I've read loads of books on how to be sneaky. It's time to put my skills to the test! Watch out, Isabella Marsh - I'm going to uncover all your secrets!
