Conan

"I can reveal the truth about one murder, but not the other two. Those murders will just go unsolved…forever. I know the truth, but for once, there's nothing I can do about it."

Conan and Sam were already hidden behind the jewelry store's counter by the time Inspector Megure, the police, and the four remaining suspects arrived. Dean was leaning against one of the displays, arms crossed.

"What's going on here?" Inspector Megure asked him. "You're one of the witnesses, Dean…Morgan, right? Where's Kudo? He's the one who called us here."

"I'm a friend of his. He couldn't make it, so he's been having me give him all the info and he told me all the stuff he figured out."

"I do remember him saying something about a friend in the area…but it's you?"

Dean shrugged. "Do you want the information or not?"

"He's solved these two murders?"

"Not really…he said he wants to solve the real murder that happened here one year ago. The murder of Michiko Morikawa, which was made to look like a suicide."

Conan watched for one person's reaction from his hiding place, and was pleased to see the suspect pale. The other three people looked confused.

"A murder? You're telling me my daughter didn't kill herself?" Yosuke yelled.

"I don't think so. There's just one thing I want to check out in the case files first, though."

"Right. Kudo asked us to bring those with us. There's not much, because it was deemed a suicide pretty quickly, but here they are."

Dean skimmed the files he had been handed. After a minute, he tapped his foot on the ground twice in quick succession.

That's the signal. I was right, on both accounts, then. Conan readied his voice-changing bowtie, which he'd already set to Dean's voice. The speaker was attached to a part of Dean's translator.

Dean hadn't been too happy at first to have Conan speak for him.

"Why can't you just tell me everything beforehand and I'll tell the cops?"

"It's important that we get all the details correct. One mistake could mean the killer walks free."

Finally, he had gotten Dean to agree. He was the only person out of the three of them who could do this; either Sam or Conan would have been too young for the police to take seriously. Even Dean, at sixteen years old, was a stretch. It was only Shinichi Kudo's name that had gotten them this far. Still, Conan thought, he's a much better actor for this than Kogoro. He won't be asleep, and the translator will hide any inaccurate lip movements.

Dean fell silent, and Conan took over.

"First, the motive. We found a lot of interesting things about Ms. Michiko when we looked closer…though she was the eldest child of Yosuke Morikawa, heir to the family's fortune, she was often shunned by the rest of the family, probably because Yosuke married her mother without Mrs. Morikawa's approval. Is that right, Mr. Morikawa?"

"Y-yes, that's right. She didn't come from a high-class family, and my mother despised her…I fell in love with her at first sight, though, and my Michiko…I loved them both, but Mother never acknowledged them."

"After she died, you remarried, though. This time to a woman of her choosing, Mrs. Akiko here, yes?"

"That's right.," Akiko answered. "We've been very happy together. Until recently, of course…"

"Yes, and you had two children together, Rintaro and Kohei. They seemed to be the perfect heirs to the Morikawa name: charming, sociable, intelligent….and well-bred, right? They were Mrs. Morikawa's favorites, right?"

"My mother played favorites, I'm sorry to admit," Yosuke said. "But you're not suggesting that she…?"

"There's no such thing as coincidences, Mr. Morikawa. Your mother and sons all benefited from Michiko's death."

"No, no!" Kohei spoke up. "You haven't even proved that her death was anything but suicide! You can't accuse us of anything!"

Dean smirked.

A much better actor, Conan thought.

"I have evidence that it was a murder, don't worry about that. She was poisoned with potassium cyanide, and the killer later moved her body and planted the bottle of poison to make it look like she'd taken it herself."

"Mr. Morgan, no," Megure interrupted. "We checked everywhere for traces of poison, but nothing was found except on her fingers. She hadn't been out anywhere that day, and both Mr. Rintaro, Mr. Kohei, and Ms. Kazuko all had alibis for the time of her death."

"Michiko had a habit of biting on her necklace, didn't she? Anyone who's been around her enough would know this. The poison was planted on the locket that she always wore."

"Do we look like fools to you? We know how to do our jobs. The necklace was one of the first places we looked, and there was nothing on it."

"Yes…nothing on the necklace she was found dead in. But that wasn't the one that killer her. Here, take a look." Dean handed over the photo album, which Megure accepted begrudgingly. "In every picture in this book, she's wearing the same necklace: a silver locket. She never took it off, it seemed like."

"I remember that necklace!" Yosuke blurted out. "It was a family heirloom. I gave it to her when she was five…I can't remember a time when she wasn't wearing it."

"Right. You can see so yourself, right, Inspector."

"Yes, and your point is?"

"Look at the photos of Michiko when she was found. Notice anything different?"

Megure took the case file and looked at the photos. At first, it was just a quick glance, but then his gaze sharpened. "The necklace…it's different! Not a locket, but a sapphire pendant!"

"So why would Michiko pick that day, the day she died, to all of a sudden wear a new necklace after over twenty years of never taking off that locket? And where did the locket go? If it was so important to her, it should have been found among her personal belongings somewhere, right? But it wasn't. Probably, the killer switched the necklaces when he was moving the body."

"It's strange, yes, but hardly incriminating."

"How about if we could show you the necklace? It's been right here, behind a locked display case, this whole time."

Dean moved off the display he'd been resting on, revealing the silver locket beneath. "Check it for potassium cyanide. If it's been preserved like this, there should still be some traces of poison, even after all this time."

The crime tech guys descended on the necklace. While they removed it gingerly from the case and ran their tests, Dean and the Inspector both watched each other.

"Inspector, he was right! There's traces of potassium cyanide on this locket!"

Megure didn't look too surprised. He'd know not to be too stunned when Shinichi's deductions turned out to be correct after all the cases he'd seen Shinichi solve. It wasn't over yet, though.

"All right, that does make the suicide more questionable…but without proof to connect her brothers or grandmother to the crime, there's nothing we can do."

"It's not true!" Kohei said. "Please, I had nothing to do with any of this!"

No one seemed to pay him much mind.

"But I do have proof. Did you know this store keeps a record of all of the purchases made? It looks like Michiko was quite fastidious. The second necklace, the sapphire one, it was bought the day before Michiko's death…by Rintaro Morikawa."

Dean passed them the slip of paper he'd been keeping in his pocket, the receipt that confirmed the details that Conan had just given them. Conan had found it in Michiko's office; it had seemed that she hadn't had time to file it into the main office before she was killed.

"But that doesn't have anything to do with me, even though Rintaro killed her! Please, I didn't know anything about it!" Kohei yelled.

"But Rintaro's alibi was almost completely reliant on you. And the way you've been acting this entire time…it seems like you must be a part of this. An accessory, maybe?"

"Please, please, I didn't do anything! Rintaro told me to meet up with him that day. He was late, but he made me promise not to tell anyone…said he had business to take care of, but when Michiko turned up dead, I….I didn't know what to think. Rintaro and Grandmother, they threatened me not to say anything….Please! Please, I didn't do anything."

"Kohei, you…?" Yosuke started. His face was pained.

"Dad, please, I…I didn't know anything, please…" There were tears in his eyes. Megure watched the pair of them, father and son, and sighed.

"Kohei Morikawa…I'm afraid we'll have to take you down to the station for questioning. I don't think you'll be getting out of this one. Likely, you'll be charged as an accessory to murder."

Koehi continued to resist, so the police had to put him in handcuffs just to get him in the car. Inspector Megure thanked Dean for his help, and asked if he would be seeing Dean around any longer. Dean just grinned and shook his head. It took a long time before the police had thinned out enough for Dean, Sam, and Conan to slip out unnoticed.

I did it. Another case solved, another killer revealed…though it looks like he was dead already. Still, I should be content, right?

Somehow, it didn't seem that easy any more.
