A/N This is a continuation of iheartphinabella05 's story Anonymous Notes ( s/8044361/1/Anonymous_Notes). I would read them first to get the plot from this point on.

The school day had passed with the other note being delivered to Phineas without incident. He had found it after third period, making him wonder just how many there would be before he figured it out. It had troubled him all day, he now sat under the tree in the back yard with his laptop on his lap, the two notes and a list to one side of him, his sketch book of inventions and notebook on the other.

I have been sitting here for two hours scanning the list of Fireside Girls that go to our school. It's was really handy that I saw Mrs. Fireside at school turning in info for the coming years graduating class. I had no idea there was eight troops in this area. Or that they all feed into the same high school. Thanks to the wonders of the internet, I have managed to get pictures on all them. Then limiting it down to only the members that go to high school. Alright, down to thirty five. Now take out all those with glasses. Down to twenty eight. Still too many.

"PHINEAS! FERB!"

He look up at the sound of Candace's voice. In just a few moments, she appeared at the back door. Seeing him, she came out holding an electronic device. Standing right in front of him, she presented the thing to him.

"Phineas, I need this fixed now! We are have to make a video for history tomorrow and mine seems to be the only one that like thse schools computers." Raising an eye brow at him. :"I'm sure you had nothing to do with that."

"Not at all. What's the problem with it?" He pulled his pocket tool kit out and fished out a screwdriver to pop the case cover off.

"It will just flash on and off. The screen comes on, then goes off. And before you ask, yes. I charged the battery. You don't have to ask me for the eightieth time." Rolling her eyes and crossing her arms as she tapped her foot.

"It's only be twenty three. Now lets see here...ok that's fine...that's the video feeder... aaaaaaa. You know, if you gave me an hour. I could add a transponder that would instantly stream video to you phone." Both hands had a tool in them and adjusting things in the video camera.

She rolled her eyes again. "Why in the world would I need that! It's not I need to spy on anyone."

His eye widened as the thoughts hit him. Plans filled his mind. A smile bloomed on his face as he completed what needed to be done. He looked down and finished camera in a hurry. Putting it back together and turning it to make sure it was done. Handing it back to Candace, he gathered up his things and was up the stairs in a flash. He burst in his room to see Ferb look up from his novel.

"Ferb, did you ever manage to finish miniaturizing the molecular phasing unit?."

He nodded and reached under his bed. Grabbing at several things before producing what looked like a wrist watch. He handed it to Phineas who looked it over before putting it on.

"Sweet. Ooo, and stylish too. You are the man, bro." Ferb smiled and gave him a thumbs up before returning to his book.

Marissa heard him and poked her head in. That is when she saw a blur of red pass her by and ran down the stairs. She heard Linda say supper was in an hour before the back door closed. She looked in at Ferb and gave him a look. He rolled his eyes before dropping his book again and returning the look.

"Where is he going?"

Ferb just shrugged.

"You really have no idea?"

"I do not stand in the way of compassion, nor do I hold back determination." Ferb stated as he crossed his arms and shook his head.

"You think he knows?"

Ferb continued to shake his head. Seeing that she was now deep in thought, he leaned back and returned to the book he hope to get done tonight. Marissa was pacing in front of his bed, a hand on her chin and the other on her hip.

"Where would he be going then?"

"You can ask him when he gets back or call him." Ferb was slightly annoyed. He had a feeling he knew what his step-brother was doing, but not for sure. There was only one reason he would not have asked Ferb for help if he had something plan in relation or the notes. That was if Phineas suspected that he was involved in it. He dismissed the thoughts, he had his own goals. If his brother didn't need, he had no problem waiting till he did.

Marrissa walk out of the room and wondered. He is already gone by now. Where could he be going? Maybe Isabella's? No, Ferb said he didn't know. But he is up to something. Should I tell Isabella? No, she would just think he had figured it out and cry when he didn't show up. I can't do that to her. GAH! Why does you do this now!

...

She was writing another note. It was almost sad to say that she was having fun with this. Unnerving Phineas was hard to do. He's sang standing on the front of a roller-coaster, for crying out load! But she had done it. With nothing but a letter.

"I guess the pen is mightier in the sword.. Right Pinky?" The light dog barked and wagged his tail. She looked back at the note.

Two down, here's three.

To think this is true

Love anonymous

She giggled as she put it in the envelope. This was far too much fun to be having at his expense. But she wanted her on his mind for as long as possible.

"Isa! Supper!"

"Coming mom." She sent a quick text to Marissa to meet her early again. Standing, she moved toward the door as something outside her window caught he eye. There was a pointy headed kid riding up to the house across the street on his bike. What is he doing out this late? She shrugged and headed down to eat.

I hope you enjoyed this addition. Please read the first three chapters if your lost. Review and be honest.
