I do not own Phineas and Ferb. May and Misty are mine.

Maybelle Is Always Right

May slipped out of bed at six in the morning. She was always an early riser, so the time didn't faze her. She ran a brush through her blonde hair and got dressed. Candace was still in her sleeping bag, snoring softly and oblivious to the sun that streamed through the curtains. May shook her head and shoved the curtains open.

Candace groaned when the sun shone right in her face. "What time is it?"

"Six in the morning," May said. "And we have things to do so get up."

"Are you crazy?" Candace asked as she reluctantly got out of her sleeping bag. "It's way too early for this!"

"You can shower across the hall if it'll wake you up."

Candace sighed and grabbed her clothes before shuffling into the hallway and towards the bathroom. May made her bed and picked up one tracking device. Frederick normally disappeared around seven, so the timing was perfect. May carefully pushed open the door of her sister's room and slipped inside. Misty was snoring and Isabella was curled in a sleeping bag. Frederick was already up and was looking directly at her.

"Good morning," May whispered. She picked him up and stroked him, slipping the tracking device on while she was at it. Frederick didn't seem to notice the new accessory he acquired. "It's time for breakfast."

She brought her frog downstairs and set him down. She made some pancakes for breakfast and put the finished products on the table. She glanced up when Candace came shuffling downstairs with her bag. "Hungry?"

"It's way too early to eat," she mumbled.

May rolled her blue eyes and piled some pancakes on her plate. "You can drop your bag off at home if you want. As well as take care of the other thing."

Candace picked up the hint and sighed. She got up and went outside. "It's not even completely light out yet!"

The teen stomped across the street and used her house key to open the front door. She crept through the dark house and tiptoed up to her brother's room. She gently pushed the door open and glanced inside. Phineas and Ferb were sleeping soundly, but no platypus was tucked under their arms.

"Sneaky little thing," Candace muttered as she headed towards her room. She hated it when Perry slept in her bed (although she made an exception once in a while) simply because he made her bedsheets smell funny afterwards.

Perry stirred when he heard the door being pushed open. He opened his eyes and tensed up immediately. Candace took a quick look around her pink and purple bedroom before her dark blue eyes fell on the platypus sleeping in the middle of her bed. Perry got ready for the screaming, but none came.

"So the second I go to stay at someone's house you sneak in here and hijack my bed." Candace crossed her arms and stared sternly at him. "I'm letting this one go, but next time you won't get so lucky."

Candace is actually allowing me to stay in here? Well, she does have strange mood swings. At least she's not throwing me from her room, Perry thought.

Candace dropped her bag by her bed and gave Perry a quick scratch on the head before leaving the room once more. I don't think I'll ever understand that girl, Perry mused before drifting back asleep.

He was not aware of the tracking device that was now attached to his neck.

...

"I still think you've lost it," Candace muttered as she lay on the couch. "Perry is not a secret agent!"

"We'll just have to wait and see," May said. The two girls were at Candace's house, monitoring their pets' movements by the little GPS devices May had. The red dot on the handheld screen was Perry and the blue was Frederick.

"Hey! They're on the move!" Candace alerted, gesturing towards her screen. May took a quick glance at the clock on the wall to check the time. It was quarter after seven.

"You follow Perry, I'll follow Frederick," May ordered. She jumped up and ran from the house without another word.

Candace looked back at her screen. Perry was moving towards the tree in the backyard. "I still think she's lost it."

She got up and crept outside, feeling ridiculous for stalking her pet. She peered around the side of the house and watched as Perry approached the tree. He took a look around (Candace moved back for a second so she wouldn't get spotted) and a hatch opened in the tree.

Candace stared. She must be seeing things. Why would a hatch be in a tree?

Perry stood on his hind legs and placed a fedora on his head. Candace clapped two hands over her mouth to keep from shrieking in shock. Her platypus jumped down the slide and disappeared. The redhead slowly approached the tree and poked at it. The hatch opened again. Candace looked at her screen. Perry was somewhere underground.

"I can't believe this," Candace groaned. She stared at the tree-slide thing and after a moment's debate, cautiously squeezed herself through.

She whizzed down some dark and narrow passages before landing with a thump on a white tiled floor. She froze and quickly looked up. She bit her lip to keep from shrieking again and hurriedly scrambled back behind some sort of rocket car.

Perry had his back to her and some man on the screen was reading off some papers. "It seems like Dr. Doofenshmirtz has bought up all the clown makeup in the Tri-State Area. Go see what he's up to and put a stop to it Agent P!"

The man lowered his papers and Candace ducked back down, biting her lip so hard she could taste blood. Perry being a secret agent was one thing, but May's father was his boss? Her mind just couldn't keep up.

Perry took off in a jetpack and the screen went black. Candace cautiously moved from her hiding spot and looked at all the tech and gadgets scattered around the place. Everything was platypus-sized.

"Okay, I'm dreaming. This can't be real."

Her dark blue eyes strayed to a corkboard hung on the wall. She approached it and studied the pictures tacked on. There was some of May's dad, some of a geeky guy with purple glasses, some of Isabella's dog Pinky ("Oh my gosh! I can't believe this!"), but most of them were of her family.

"What the-?" Candace leaned closer and studied a few pictures with confusion. There was one of Phineas and Ferb posing with Perry in what seemed to be mine carts and one of them holding up a lawn gnome with her looking annoyed in the background. There were some more pictures of Phineas and Ferb with Agent P.

"I don't get it! Do Phineas and Ferb know about Perry's secret? But if they did, that means I would too considering I'm in one of these strange pictures. When the heck did I get shackled up anyway? Oh man...brain overload."

She took a deep breath to calm herself. "Okay, contact May," she said aloud. "She'll know what to do."

But when she searched her pockets she realized she left her phone charging in her room. Candace ran a hand through her red hair. "How do I get out of here?"

A green light started blinking on the white and blue console. Candace moved forwards and looked at it. It read, AGENT F REQUESTS VIDEO CHAT. ACCEPT COMMUNICATION LINK?

"Agent F...I really hope this is May calling from Frederick's lair/base thing." Candace slapped the accept button before she lost her courage and tensed. What if Agent F is a ferret or something?

May's smug face flashed on the screen. "I told you so."

Candace scowled. "You do realize your dad is the boss of who-knows-how-many secret agent animals?"

The smug look instantly vanished. "He said he was a police officer. I can't believe he lied to me! I thought Frederick trusted me..."

"Yeah well, Perry didn't tell us either," Candace pointed out.

"I was searching through the data files. The security here is kind of lousy. It turns out that if an agent gets discovered by their host family, they'll have to be relocated."

"That makes sense," Candace said slowly. "But we're just a cover for him?"

"Please. I've never seen a platypus who loved his family more than Perry. Frederick, on the other hand, has no reason not to tell me. I mean, my dad's the boss for crying out loud!" May cried.

"I think your dad just wanted to protect you and your siblings," Candace said.

"I'm still upset," she grumbled. "But we found out what we wanted to know."

Candace ticked the discoveries off her fingers. "My brother's projects disappear because of Dr. Doofenshmirtz's –Inators. My pet Perry is the nemesis of Dr. Doof. Your dad is the boss of my pet Perry."

"Geez, talk about interlocking fate," May muttered.

"The only thing I don't is why there are pictures of me, Phineas and Ferb with Agent P. I don't remember ever seeing Perry as Agent P!" Candace frowned. "Well...except the time when I was hallucinating." Then it hit her. "But I wasn't hallucinating! I was really seeing it because the moss I thought was hallucination moss was not the right moss!"

May blinked. "Uh...sure. Whatever you say. As for the pictures you don't recognize I have no clue. Maybe you got hit by some amnesia ray or something."

Candace sighed. "What do we do now?"

May stared around Frederick's lair. "We say nothing. I don't want to have Perry relocated from you guys. I'll keep my mouth shut in front of my dad and talk to Frederick in private."

"Alright." Candace nodded. "How do we get out of here?"

"Press the big red button. By the way, how did you get in there?"

"Tree slide," Candace answered.

"Nice. I went down an air chute."

"Oh, there's something else!" exclaimed Candace. "You know Isabella's dog Pinky?"

"Don't tell me. Secret agent?"

"It's so weird!"

"I know," agreed May. "We better get out of here before our pets come back." May pushed the red button and she was suddenly sucked up and went out of sight. The screen went black and Candace wearily pressed the same button on Perry's console. She shrieked when she was sucked into a tube and rocketed upwards before landing on the front lawn.

"Okay, that was scary." Candace got to her feet and shook herself off. May entered the backyard a minute later and collected the GPS screens. "You were right."

May shrugged. "I'm always right-most of the time, anyway."

...

Across the street was a white van. No one took much notice, as it wasn't particularly attention-drawing. The owner of the vehicle hacked into the traffic-cam security feed, taking particular interest in the camera located across the street from the Flynn-Fletcher residence.

The person was still, eyes locked on the images displayed on the screen, a twisted grin on his face.

It had taken a while before he finally managed to track the elusive Major Francis Monogram down. If it hadn't been for a website flub from the stupid intern, Carl, then he never would have been able to track Monogram down.

In the backyard, his target was conversing with a redheaded teen. The man took a quick account of her looks; blonde hair, blue eyes, black skirt and pink button-up shirt. In fitting with his data, this was Maybelle Monogram.

His eyes strayed to another screen that showed a ten-year-old girl playing with two boys and one girl. She had snow-white hair, blue eyes and wore a white t-shirt with lavender sleeves and black pants. There was no doubt about it. This was Misty Monogram.

Montgomery Monogram was currently unattainable. He was spending the forthcoming weeks at his prestigious school, where the security was so great even he would not dare breach it. He could not wait for the teen to return home-he needed to enact his plan as quickly as possible.

But it did not matter. Two out of the three kids was more than enough.

It was a good thing Carl kept pictures of the Monogram children on his website. And it was an even better thing that he listed Danville as his hometown. From then on it had simply been a matter of tracking down where Monogram lived.

"Now all I have to is wait," he said softly.

Major Monogram would agree to nothing if he was abducted. The man would take the pain and die before telling any secrets.

But if he took the two girls? Well, Monogram would certainly do anything to get his daughters back.

Anything.
