Welcome to the long-awaited "The Agents of the Opera." This will have some basis on the movie and the play, but I'm gonna try to shoot more for what happened in the book. I won't spoil anything, but I have a feeling people will be much happier than they would have been otherwise. It'll be a little bit different though, so be prepared. I do not own The Phantom of the Opera nor do I own Phineas and Ferb. The rights to all products go to their proper owners. All right, let's go!

Prologue

It was a typical summer day. Phineas and Ferb were sitting under their favorite oak tree with their friends, Isabella, Buford, and Baljeet. They were trying, for the life of them, to figure out what to do. Candace was inside with her book club. They too were trying to spark the day… but it was hard to do that with a dry classic.

Penelope, Perry, and their children, Max and Rosalynn, were outside with the kids. They looked back and forth between the two groups of kids. Penelope sighed and went inside. She nabbed one of the books from the book club and was soon chased outside by the teens. She brought it to Phineas and the boy was, for once, at a loss.

"The Phantom of the Opera? I didn't know there was a book for this," said Phineas.

Isabella gasped and snatched the book from Phineas's hand. "I love this book! It's so romantic and heart-wrenching and terrifying. It gives me chills just thinking about it," she said.

"If it's so exciting, why is it so hard to get into? I mean, look at this intro: Blah, blah, blah, true story, blah, blah, blah, gathering the facts, blah, blah, blah, real ghost… I mean, who would believe this?" asked Candace.

"Actually, I would," said Irving, poking his head over the fence.

"What do you mean? Is The Phantom of the Opera really a true story?" asked Isabella.

"Well, it didn't happen quite the same way as it did in the book. My great-great grandfather was a historian who searched for the truth in the myth. The opera's phantom was just one of his many cases," said Irving.

"Prove it. Show us some old-timey things," said Buford.

Irving pulled out a book from behind his back. "I just so happen to have my great-great grandfather's phantom case here!" He opened the book. There were many news clippings and old photographs. There were also letters written in black ink and a faded red that was reminiscent of dried blood.

Irving continued: "It actually happened between a few animals. The Opera Populaire would take in humans and animals that didn't have any other place to go."

"Like a shelter," said Isabella.

"Exactly that and not only were they provided with a home, but they also got a chance to make a lot of people happy with their skills in the performing arts," said Irving.

As Irving flipped through the pages, he came across one that had a picture of a platypus that looked like Penelope. Phineas stated as much: "Hey, that platypus looks just like Penelope."

"This is a picture of Penelope Daae, a great singer for the time. They used some sort of technology that made it so that humans could understand the voices of the animals. These are clippings of just a few of the reviews that praised her to heaven. She was the Angel of Music for that time, her skill unmatched by anyone before nor since then," said Irving.

"Daae… isn't she the one in the book that winds up missing?" asked Isabella.

"Ah, yes, the affair of Penelope Daae and Viscount Peter de Chagny. There was rumor that the Viscount was responsible for the murder of his step-brother, Count Phillip de Chagny. Ever since the Count's death, neither the Viscount nor Miss Daae were ever heard from again," said Irving. "My great- great grandfather thought that the phantom killed the Count and also that the phantom was responsible for the disappearance of the Viscount and Miss Daae."

"Kidnapping, killing, and romance? I knew you guys would make this exciting," said Candace.

"Would you tell us the story?" asked Isabella.

"Sure, I'd be happy to. Now, let's see… where does it begin…?" asked Irving, flipping through the pages.

Penelope smiled and nudged her family. "Pay attention, kids, I think you'll want to hear this story," she said. When Irving found the beginning of the story, he began telling it.

There's the intro into the story. Please keep reading and reviewing, thanks :)
