Author's Note: This is my first fan-fiction piece, and I honestly do not plan to these things regularly. I only posted this because I actually did this for school. In my AP Literature class, we had to write a "Famous Beginning," meaning just write the first page of a book. I edited it slightly to be more obviously Phineas & Ferb related, but it is almost identical.

Disclaimer: I do not own Phineas nor do I own Ferb. Dan Povenmire, Jeff Marsh, and Disney do.

Waking with a start, I fell out of bed and onto the wooden floor. As I stood up wearily, I could not remember to what I had awoken. Was it a car? Was it a dream? Did Perry knock something down again? Then I heard it again, and it was none of the above; I could hear not-so-subtle footsteps moving around downstairs.

I knew a neighbor of mine, Ms. Marsh, had been robbed a few days ago. Luckily, they only had time to steal an address book. (Ms. Marsh is both a light sleeper and a gun owner, so those criminals were out of her house pretty quick).

Then I realized something. I was listed in Ms. Marsh's address book as the head of the Neighborhood Watch. That had to be it. The robbers wanted to attack where it hurt the most. Steal from the head of the Neighborhood Watch and one could strike fear into the hearts of the whole neighborhood.

I was not about to let those thugs come into my town and terrorize my friends. With a TASER in one hand and a baseball bat in the other, I crept out of my bedroom and into the hallway. I listened intently as I snuck down the stairs, being careful not to step on the bottom step (it creaked). Now that I was on the same floor as the trespassers, I had to be really careful. Ms. Logan said she saw two people running from her house. I could easily handle two average criminals if necessary, so long as they thought I was still asleep.

I took another moment to listen for any movement, and I realized two things at once: first of all, there was only one set of footsteps, not several. Second, they were quiet footsteps, but they were not sneaky, they were just light. This did not add up. Who would be stupid enough to burglarize someone's house by themselves? Whoever they were, they did not sound like professionals. The way they were rummaging through my cupboards- I stopped short. I smelled coffee. How cocky was this person?

I wheeled around as I heard a soft chirping sound coming from the room behind me. It was my pet platypus, Perry. He was awake and completely aware of someone being in the house, and he was not doing anything. Not that I was surprised; that platypuses never did do much, especially at his age, but still, he did not look concerned at all. That could mean only one thing; he knew the person who had broken into my house.

Perry walked around me, heading towards the kitchen. It almost seemed like he was motioning for me to come with him. Still ready to fight, I hesitantly followed Perry. As I rounded the corner, I froze. None of my thoughts could have prepared me for what, or should I say who, I saw. Sitting in a chair, looking into my eyes while calmly sipping coffee, was a long lost childhood friend, the girl from across the street.

"Isabella?" I asked, completely bewildered.

She responded simply, "Hey Phineas, whatcha doin'?"
