Hello, everybody! It's my first attempt in fanfiction and it's really weird idea... Besides, English is not my native language. But I think, I have to try writing this kind of story. So, please, bear me for time being…

Summary: What if Shinichi's and Ran's roles were interchanged: Ran was the daughter of Yusaku and Yukiko and a great detective, and Shinichi - the only son of hopeless private eye Mori Kogoro? What could happen after the roller coaster incident?

Disclaimer: I don't own anything.

The atmosphere was grim and silent. It couldn't be otherwise in that place – the room where the murder occurred. The victim was the owner of one of the biggest pharmaceutical company – Suda Taro. Somebody stabbed him in the back. And now police had no clues. Of course, there were four suspects – Suda Rinko, the wife of murdered man, his best friend Hirano Ken and two sons – Shota and Jiro. All of them had their motives. The problem was that there was neither evidence, nor even clues. Complete deadlock.

The stout man in the hat - inspector Megure – frowned. He didn't want a cold case, yet it seemed that that mystery would become unsolved. Inspector was sure that the real murderer was smirking mentally at the moment.

But still, police could do nothing.

"We're going to leave. The investigation will continue tomorrow," said Megure without trying to hide his irritation.

"Please, inform us when you find the culprit," asked Rinko.

"We'll call you if we find something," promised inspector.

"I don't think you'll need it as the case is already solved" spoke a serious voice from behind. Everybody turned around and saw a girl with long dark hair.

"Ran-kun? What are you doing here?" exclaimed Megure with great surprise. One of police officers scraped the back of his head:

"Actually, Ran-san has been here for a while… You see, she was passing by and noticed police here…"

"And you haven't tell me a thing, have you, Takagi-kun?" inspector frowned. Sometimes he really thought his assistant was hopeless. Nevertheless, Megure was glad to see the girl. Ran was the only daughter of his friend Kudo Yusaku, who was famous for both his writing and deductive skills. Moreover, it seemed the girl had inherited her father's great mind: some time before she began to solve the most difficult cases, so that she even was called 'The savior of police' by media.

"What do you mean by 'the case is solved'?" asked Hirano with irritation. "The police have found no evidence! Are you saying you know who the murderer is?"

"Of course," answered Ran without any doubt in her voice. "It was the second son – Jiro-san. He owed a great deal of money and was chased by his creditors. If his father Suda-san helped him, Jiro-san could get out of his problems. But the old man was really greedy, so he cruelly refused to…"

"Ridiculous!" yelled Jiro angrily. "You have no proof! It's only your silly deduction!"

"Really!" nodded Rinko. "My son couldn't kill his own father!"

"Ran-kun, are you sure?" asked inspector. "Jiro-san said he hadn't seen his father for a while because of their quarrel. His mother and brother confirmed it. Are you saying that they lied?"

"They simply don't know that Jiro-san secretly came to his father begging for money. Here is the proof," Ran took out a lighter. "It was found in Suda-san's cabinet. The victim didn't smoke, as well as Rinko-san, Shota-san and Hirano-san. You're only one who smokes. And pretty sure we'll find your fingerprints on the lighter. There are also blood stains on it".

"So what's now?" for a second Jiro tensed, but then smiled arrogantly. "I simply left my lighter in the cabinet by mistake during my last visit. Maybe, the murderer accidentally dropped it off the table…"

"Actually, I lied: this lighter was found by one of the maids in the corridor," Ran smiled. "She recognized it as yours and decided to return it to you. Then somebody found the body, and she simply forgot about the lighter. She's quite absent-minded, that maid… Jiro-san, you dropped your lighter right after the murder. You panicked and picked it, but then lost it while running away. You know it yourself: the blood stains on your lighter came from your blood-stained fingers…"

"Enough," said the man quietly. "I really killed my father. He was a real monster who didn't want to help even his son. He laughed at me when I begged him at least lent me some money! I was enraged. When I came to myself, he was lying in the ground motionless…"

"Have you heard the news? About Suda Taro's murder case?"

"The police could do nothing!"

"Yeah, that Kudo girl is really something!"

"She is the savior of police, after all".

The group of chatting teens passed the dark-haired highschooler, who was reading a newspaper. It was Shinichi, Ran's childhood friend.

'Somehow, she managed to solve another murder case. Can't she find something more appropriate for girl than dead bodies?' he thought with a sigh. Shinichi knew Ran for many years, but still couldn't fully understand her crazy love for mysteries and cases.

Suddenly he spotted his childhood friend talking to the group of their classmates. Shinichi mentally facepalmed. Great, now Ran surely was boasting about her famous deduction. Maybe, she wasn't too conceited, but she really liked to attract everybody's attention. Perhaps, she inherited that trait from her mother, the famous actress.

At last, Ran left her fans and noticed the boy.

"Hi, Shinichi!"

"Hello, Ran," Shinichi frowned. "I've seen the news about Suda's case…"

"It was a piece of cake," the girl shrugged, interrupting him.

"That's not what I mean… Do you really enjoy all these murders, dead bodies, investigations and staff?"

"I simply want to find the truth," said Ran. "And criminals must be put in jail".

"You can leave solving the cases to the professionals. By God's sake, you're still in highschool!"

"By 'professionals' you mean your father, don't you?" Ran smiled mischievously. "Old Kogoro is really hopeless. Does he still watch TV and drink beer all day long?"

Shinichi didn't know what to say against it. After all private eye Mori Kogoro was really not so great. It was a miracle if he somehow managed to solve simple case. And of course, most of time Kogoro was drinking, watching TV or playing mahjong.

"It has nothing to do with dad," at last replied Shinichi. "I meant police".

"You've seen it yourself. They are not able to solve everything," disagreed Ran. "Besides, I love mysteries…"

"Still, these cases are dangerous, especially for girl," insisted Shinichi. "If you like mysteries, you can simply follow your father's footsteps and write a book…"

"No way! I don't like to create puzzles, I like to solve them," she seemed slightly irritated.

For some moments they both was walking silently. Suddenly a ball rolled before them. Ran looked around, noticed some children playing football and passed them the ball.

"Thanks, nee-chan!" exclaimed one of the children.

"You like football, don't you?" asked Shinichi. Well, it wasn't the most appropriate hobby for a girl too, but at least, football was much safer than chasing the criminals.

"I know, what you want to say," said Ran. "But I play football to be fit. Isn't it the same with your karate?"

"Yeah," Shinichi nodded nervously. Actually, he began to do karate many only because he wanted to protect Ran, who tended to get into trouble from early age. After all, Shinichi secretly loved her for years, yet his childhood friend, even being great detective, didn't notice his feelings at all.

Suddenly the teen remembered something. In fact, Shinichi was going to speak with Ran about something else before he saw that morning paper.

"Look, Ran, you know that I've won last karate tournament, don't you? I wanted to celebrate it with some friends, but then everybody got very busy…" Biggest. And. Dumbest. Lie. Ever. No way, that Ran with her deductive skill would believe him. At least, Shinichi was glad that it wasn't his plan to invite the girl for a date.

Surprisingly, Ran hadn't suspected a thing:

"And where have you planned to go?"

"Tropical Land".

"That new amusement park?" asked Ran. "They say it's great, but I've never been there".

"Then… Would you like to come with me?" suggested Shinichi. It was much more difficult than he thought. He could be fearless, confident and honest, but when it came to his feelings for Ran, Shinichi felt himself helpless and lost.

"OK," the girl nodded, much for his surprise. "Let's meet at four near the gates".

No one of them knew that the evening would become one of the most fateful events of their lives…
