Just when the granddaughter of the multinational magnate was about to speak to that old man, she got hit by the little detective's tranquiliser, and he saw it all happen. How that pesky little detective was suddenly picked up by Ran and accidentally pressed that devil's button on his stun-watch in the progress. He already saw the detective sweat in panic at the incident as the heiress fell with her back against the glass tank.

"Sharon-san? Are you alright?" Ran called out as she released the boy as he saw the child furiously turn the dials on his voice changer.

At the same time the Suzuki heiress and the tomboy detective came closer as they both watched the unconscious girl.

I don't need to explain myself to you. I believe you're smart enough to figure it out eventually. And for your information, he's awake. I'll get us out of here.

As the confusing words rang through his mind, he let out a sigh. Despite that she clearly stated that she would hunt him down for impersonating her boyfriend, she still wanted to help him out. He did not understand it and yet he felt obliged to help her out in this situation. Besides, that great detective would be indebted to him. If he was correct, he would not dare to use his little bow tie in presence of the tomboy detective. It was too risky.

"Hey, Sharon. Are you awake?" The tomboy asked.

Seeing her reaching for her shoulder, he grinned as he made his decision, "I'm fine, don't worry." He said, using Sharon's voice. He made sure his lips were not moving, to hide the fact that he was the one talking.

Getting closer he got on his knee and inspected the girl, "Are you sure, Sharon?" He said again, but this time in her boyfriend's voice, Dino.

"Yes, I'm fine, Dino." He said again, using the girl's voice in ventriloquism. It was also then that he noticed a soft yellow shine, barely visible, from her wrist. Inspecting it quickly he saw that it came from her bracelet and for what he knew, the gems on the bracelet were stones he had never seen before.

"Suzuki-dono, inspector Nakamori, I wanted to tell you that the turtle carrying the red diamond, the Blush Mermaid, on its back was not stolen…" He heard as he slightly froze up. Apparently that detective took over the moment he was absorbed into the particular gems. Standing up, he glanced over to the bespectacled boy as he saw him grin victoriously. He miscalculated. The boy dared to use his voice changer in the present of Sera Masumi. "It was in fact just hidden out of our sight."

"Hidden out of our sight?" Nakamori inquired.

"That is correct, inspector Nakamori. To show you the proof… Conan-kun, you know what to do, right?"

"Un, got it, Sharon-nee-chan!"

As he watched the bespectacled boy walk up to him, he frowned slightly as the detective smiled innocently, "Do you have a 50 yen or 100 yen coin, Dino-nii-chan?"

Just when he about to check Dino's wallet in the back pocket of the trousers he froze, taking out the wallet and taking out a coin means that he would leave behind fingerprints. Especially on the coin that will not be returned afterwards. It would be suspicious for a multimillionaire like Dino Cavallone to ask a merely 100 yen back. It was a bad idea to do that. If he did, then the police would have something physical on him, as Kaitou Kid.

"I'm afraid I only have my credit cards with me. I'm sorry, Conan." He decided to say, along with an apologetic smile.

As he saw the boy frown slightly he took his chance, "Inspector Nakamori, do you have perhaps a 50 or 100 yen coin." He said in Sharon's voice, using ventriloquism again, as he saw Conan's frustrated look.

"Ehm… Yes, I do." The inspector said as he took out a 100 yen coin from the inside of his brown jacket.

"Please drop the coin above the name plate, inspector."

"How is this going to help us understand anything…"Nakamori muttered as he dropped the coin in the tank, above the large golden plaque. However, when the coin failed to reappear, his expression changed. "Huh!? What? It didn't fall!? What just happened?" Climbing on the stepladder, that was still there, he climbed up and looked over the edge. "AH! It's stuck! How?"

"A magnet. That plate is a really strong magnet, isn't it?" The tomboy detective stated as she walked closer to the plate. "A 100 yen coin is made of 75 per cent copper and 25 per cent nickel. The nickel is magnetised by the magnet."

"But even if this is a magnet, that doesn't help solve the mystery of how the turtle vanished. It's not like that turtle would stick to a magnet…" Nakamori stated as he looked at the detective. "Besides, the ornamentation surrounding the jewel had a gold necklace. Gold isn't attracted to magnets… The only thing that would stick would be the necklace clasp."

"There was a lot stuck to the turtle's belly as well…" He heard Sharon's voice again, trying not to click his tongue.

"Oh, come on… Those were diamonds…"

"If those were all synthetic diamonds, maybe they would stick to the magnet, inspector?" He saw Conan speak through his bow tie. The fact that the little detective showed him that he was using the tie, most likely means he knew that he was the imposter. "Because when you make synthetic diamonds, sometimes an iron or nickel solvent is taken into the crystal as an inclusion."

"I-Inclusion?" Nakamori called out. At the same time Ran and Sonoko hummed in surprise as the tomboy nodded in confirmation. It was also then that he noticed a change in breathing in the magnate's granddaughter. He also noted that the slight yellow shine had disappeared. Did she already regain conscious?

"Anyhow, the turtle was swimming in the tank, so it was impossible to hold it in place simply by magnetism. But I'm sure that the plate had at least enough strength to attract it." He heard Conan continue as he watched the girl. He saw slight movements in her fingertips, but she kept herself still. She definitely had woken up. Glancing over to the little detective, he smirked ever slightly in amusement. The boy was so in trouble.

"Attract it?"

"Yes, please tell me what happened to the 100 yen coin, inspector."

With a frown the inspector reached for the coin, but when he tried to retract it, he called out. "Ah! It's not just a magnet. The glass on the back of the plaque is covered in glue. If a turtle got stuck on this it wouldn't be able to move!"

"But how did the turtle go to the plaque anyway?" Ran asked.

"He used bait. A little iron dust was most likely mixed in with the turtle's feed and spread around so that it stuck to the back of the plate. The turtle, with its highly acute sense of smell, would have risen up from the bottom of the tank to float beside the glass and would have got stuck in Kid's trap. Turtles have after all a keen sense of smell, haven't they, Dino?"

Surprised at the sudden mentioning of the name he just laughed nervously as well confirming it, "Y-Yeah, they have a keen sense of smell indeed."

After glaring at the bespectacled boy, the small detective just continued with a content grin. "The device used to spread the feed was probably put on the chandelier. It was set into motion when the carpet covered up the tank. The length of the turtle is around 10 centimetres and with a plaque that size would have easily allowed the turtle to hide behind it without being seen."

"That would mean that Kid's accomplices were mixed in with the workers who made the tank…" Jirokichi muttered. "Just as expected of the Magician Under the Moonlight, he's very good."

Hearing the latter he had to suppress a grin. His assistant is very good indeed and he did not know what to do without him.

"This isn't the time to be praising him…" Nakamori muttered as he looked back from on top of the ladder. "Wait a minute… If the turtle's supposed to be stuck on the back of the plaque… Why isn't it there now!? We drained all the water and searched it from end to end!"

"Somebody removed it secretly and has it even on themselves now." Conan said, continuing as Sharon.

"Hah?! We finished searching everyone here!?" Nakamori shouted irritably.

"There is one person, isn't there? Who didn't conduct a body search…"

"Do… Do you mean me?" Ran called out in panic as she pointed at herself.

All of the sudden the body next to him moved as the real Sharon looked up, smiling at the fierce karate champion. "No, I don't mean you, Ran-san."

Seeing the little detective jump back in horror, he tried his best not to laugh out loud. This heiress was definitely more than just an heiress.
