As the sun once again rose on the quiet city of Danville, six adults were alert and wide awake. Each knew that this day was more important than the weather was letting on. While it seemed like it would be a calm and uneventful day, those six people knew that the day was going to be anything but uneventful.

"How much longer Ferb?" Phineas asked, leaning over to look at his brother's watch.

"We usually start inventions at around seven," Ferb said, "which is in thirty minutes."

"I can't wait that long," Phineas said, throwing his hands in the air. "I want this over with as quickly as possible."

"I know you do," Ferb said, putting an arm on Phineas's shoulder. "But any change in our routine will tip Irving off. We have to make this as normal as possible."

"Ok," Phineas said, taking a deep breath. "Run the plan by me again."

"Vanessa and I are going to take a walk to the park with Perry," Ferb said, winking when he said his pet platypus's name. "We'll walk past where Irving work's and casually mention what you're up to today. You, Buford, and Baljeet will be working on the invention. At around ten Candace will come outside and start yelling."

"I'll make sure she's awake by then," Jeremy said. Ferb nodded in understanding.

"Good," Ferb said. He turned to Phineas. "After you're finished, you'll ask if anyone would like to play with the invention. Irving won't be able to pass it up. But you have to make sure he doesn't leave for any reason. Got it?" Ferb asked.

"Yes sir," Phineas said, mock saluting his British brother.

"Shut up," Ferb said, smiling. Phineas laughed and put his hand back down.

"One final question," Phineas said.

"What?"

"Should the chess set be muggle or wizard?"

"Do you think Phineas will be okay on his own?" Vanessa asked, her arm linked around her husband's.

"I'm sure he will be," Ferb replied. "Don't you think so Perry?" Both adults looked down at the leashed platypus who only grrrd in response.

"So where are we supposed to say the line?" Vanessa asked.

"Right up here," Ferb said, pointing ahead of them. "He works at the photography store."

"I can't believe he has been spying on Phineas for the past ten years," Vanessa said. "Why is he so obsessed?"

"Who knows," Ferb said. "I think there's something wrong in his head."

"I can't believe what Phineas is doing today!" Vanessa suddenly exclaimed.

"Well, at least he is finally acting like his own self," Ferb replied.

"Yes, but to make a life-size moving chess set is a bit extreme don't you think?" Vanessa replied as they passed by the shop.

"Grrr!"

"See Perry agrees with me!"

"Perry's a platypus, he doesn't do much."

"He agrees with me at least," Vanessa said. "We have a special connection."

"Fine whatever," Ferb said. "But we need to be careful, Irving could be dangerous."

"Oh come on," Vanessa said. They had finished with the first part of their mission and now they were back on their original topic. "It's Irving we're talking about."

"But what if Irving kidnapped Isabella," Ferb said. "That makes him dangerous."

"True," Vanessa said, looking behind her. "Do you think he fell for it?"

Before Ferb could reply, a ring came from his pocket. Ferb took out his phone and read the new text.

Irving's here. Let the games begin.

Harry Potter reference. Sorry, couldn't resist.
