Mario stayed in Peach's castle that night. He was too afraid to go back to his own house. He was in a pink bed in one of the guest rooms which (naturally) was bright pink. There was a knock at the door.

"Come in," Mario said. He was wide awake and had been for most of the night.

Peach entered the room with a breakfast tray. She set it on the bed and sat down next to it.

"Morning," she said. "Sleep well?"

"What do you think?" Mario replied sitting up and rubbing his sleepy eyes.

On the breakfast tray was a newspaper. Mario saw the word 'Yoshi' so out of interest he picked up newspaper and read it. This is what it said:

Mystery Murderer strikes

A dinosaur named Yoshi was found dead this morning Detectives are saying it was definitely a murder but are yet to work out who the murderer is.

I bet I can guess Mario thought.

The murderer left a note saying 'I've had my fun, now time to get serious. I'm coming for you next brother, watch your back.' Could this be a clue? Detectives are urging anyone who has any idea who the murderer could be to contact the police immediately.

Mario put down the newspaper. He couldn't bear to read anymore.

"Terrible isn't it," Peach said. "About Yoshi."

Mario nodded. He'd known Yoshi since he was a baby, he was like family. Mario felt terrible that he hadn't been able to save him.

"So, what are you going to do?" Peach said.

Mario sighed. "I don't know, Peach," he said.

"Well you have to do something, he's coming for you next," Peach said.

Mario looked at the bed covers, then at the wall, avoiding eye contact.

"What can I do?" he said. "I can't kill him, I know I should but I just can't. He's my brother."

"Are you gonna tell the police?" Peach asked.

Mario shook his head. "I can't. It's not his fault, I know it's not. I think he's had a spell put on him, by Kamek probably. The police wouldn't understand though," he said.

"But if you won't stop him and no-one else will then-"

"Can we just shut up about Luigi now? I'm stressed enough as it is!" Mario shouted.

"Sorry, Mario," Peach said. Suddenly, she thought of something. "Mario, you'd like your house back wouldn't you?"

"Yeah, but Luigi's there, I'd hate to face him again," Mario replied.

"Luigi has a mansion, right?" Peach enquired.

Mario nodded.

"Well don't you think that now Luigi's… well, you know, he'll want to stay in a place more sinister?" Peach continued.

"Maybe," Mario mused. "I don't know if I want to risk it though."

"Well you'll have to get you're house back eventually," Peach said. "I'll come if you like."

Mario nodded. "OK," he said. "I'll do it."

Mario, Peach and Toad stood outside Mario's house. Toad was petrified out of his mind. He was trembling and whining because Mario had pretty much forced him to come. Partly so that he was safe from Luigi but mostly because Mario wanted backup. Mario was almost as scared as Toad but he was trying not to show it. He had to be brave. Peach wasn't as scared as the others. She was pretty sure her prediction was correct and that Luigi was in his Mansion right now but still, she couldn't help but be a little nervous.

Mario put the key in the lock and turned it slowly, silently. He placed his had on the doorknob, took a deep breath and pushed it open.

The house was silent. It was dark too. Toad went to turn the light on but Mario stopped him. Luigi could be anywhere he thought. He can't know we're here.

They wandered through the house silently as a three.

"Luigi could be hiding anywhere, waiting for us," Mario whispered.

"Then why can't we just go home?" Toad whined.

But to Mario, this was home. If he couldn't live here, he'd feel like a lost soul. He wasn't about to lose his house to a crazy, psycho murderer.

There was a loud smash behind them.

Mario and Peach turned around and saw that Toad had just knocked a pot plant off accidently.

"Sorry," Toad whispered.

"You're paying for it," Mario whispered back.

Harsh I know but when Mario was scared he tended to be a bit snappy.

Mario crept up the stairs and gestured at the others to follow him. He entered his bedroom, looked around nervously and sighed with relief when he realized it was empty. He flicked the light on and sat on the edge of the bottom bunk bed.

"I think we can safely say that Luigi's not here," Mario said.

Toad sighed with relief and sat on the floor for no apparent reason.

"Thanks, Peach," Mario continued. "For persuading me to come here."

Peach smiled but before she could reply, they heard the front door open and someone come in.

Mario's heart sank. He knew who that was. The only person other than him who had a key to the front door was Luigi.

"It's Luigi! Everyone hide!" Mario whispered.

Mario and Luigi's room was extremely small so there weren't that many hiding places but Peach hid behind the door and Toad hid behind the curtain. The only place Mario could find to hide was under the covers in the bottom bunk. He knew he was painfully visible but he daren't come out. He heard Luigi come up the stairs muttering to himself. Mario's heart was beating so loudly, he was sure that someone could hear it. Luigi entered the room and the 10 seconds of silence was pure torture. Luigi walked over to the bed and lifted the covers. Mario looked up at his little brother; he had never been more terrified in his life.

"What are you doing in my house?" Luigi demanded.

"I…I'm sorry, I… I just…" Mario stuttered, unable to get a sentence out.

"Don't worry brother, it just so happens, I've been looking for you," Luigi said.

Mario couldn't speak.

Luigi took out a dagger and Mario saw his pale blue eyes flash red. He knew what was coming next.

Mario screamed. Peach ran out of her hiding place shouting: "No! Don't hurt him!"

Mario curled up into a ball. He had been hoping that Peach would stay hidden so that she wouldn't get hurt. Now there was only one thing he could do. It had no chance of working, but it was Mario's only hope.

"Luigi, please stop this," he said. "This isn't you, I know it's not. I don't believe you're evil. But you need to stop acting like this. I love you, more than anyone else in the world but if you don't stop I don't know what I'm going to do. The whole of The Mushroom Kingdom wants me to kill you but I just can't, you're my brother. I know that saying this isn't going to change anything, but please Luigi you need to know this, the real Luigi. Not the crazy psycho murderer, the adorable coward. The green thunder or whatever you like to call yourself. The amazing back flipper, the Daisy mad, the ghost hater but most of all you're my brother. And I don't know what I'd do without you."

Luigi stopped. He blinked and his red eyes turned blue again. He dropped the dagger on the floor. "Really?" he said. "Is that really what you think of me?"

"Of course it is!" Mario replied.

Mario had never been so happy in his entire life, the spell was broken, Luigi was good again.

"Even after I killed Toadsworth and Yoshi?" Luigi enquired. "I feel terrible about that."

"That wasn't your fault!" Mario said. "I knew it wasn't. I know you too well Luigi and I knew you would never hurt anyone, especially not our friends."

"So, how did you turn evil?" Peach asked.

"Well, I think that there was something strange up with that banana peel you threw at me in racing yesterday," Luigi said. "I felt weird and woozy for a bit, and then suddenly, there was a voice in my head. It's hard to explain but it was kinda like I had split personality disorder. The voice in my head started to control my thoughts and my actions, my personality, even my voice! It was so strong, there was no way I could compete, I had no choice but to watch the destruction that it caused."

"But that speech I gave broke the spell," Mario finished.

Luigi wiped his eyes. Mario suddenly threw his arms around Luigi and hugged him.

A tear ran down Mario's cheek. "Never do that again," he said.

"I won't" Luigi replied.

"Well thank god that's over even if it had the cheesiest solution ever," Luigi said. He rubbed his face. "I don't think I'll ever be able to eat a banana again after that."

"Me neither," Mario replied. "Or go racing."

"I don't know about that," Luigi said. "I love racing; in fact, I fancy a race right now."

"OK, I guess but no banana peels?" Mario said.

"I promise," Luigi replied.

"Oh, and Luigi?"

"Yeah?"

"There's a ghost behind you!"

"WAAAAAAAAAAAHHHH!"

Mario burst out laughing. There wasn't a ghost; he was testing to see if the spell really had broken.

"Let's go then," Mario said and the three of them headed out the door.

"Wait!" a voice from behind the curtain said. Toad ran out looking angry. "You almost accidently left me behind!"

"I wouldn't say accidently!" Mario replied laughing.
