Sorry about the late update, but I've had a ton of meetings in the evenings, with a ton of homework to go with it. This chapter has more investigation, and the truth comes out!

Chapter Fourteen

Heiji and Kazuha had gone to the Kudo Mansion to keep an eye on Ai. When Ai had left that morning, Kazuha had disguised herself somewhat and followed her at a distance, using the pair of tracking glasses that Conan had lent her. She hadn't seen anything odd, and had told Heiji so. She'd gone instead of Heiji since Ai would be less likely to recognize her.

Heiji had done something a little risky while the girl had been gone. Agasa had been gone, too, so Heiji had snuck into the house through an open window, and looked through it for any incriminating evidence. All he found, or rather didn't find, was the Conan costume that Conan had reported that Ai had used before, and Heiji wondered why it wasn't there. He quickly checked to see if he'd brushed against or moved anything and then had snuck back out and gone back next door.

Twenty minutes later, Kazuha had returned, and they informed Conan about what had happened via phone.

"She doesn't have the costume?" asked Conan incredulously. "She said she'd hold on to it, just in case. Nothing was there?"

"Nope. No wig, no fake glasses, no mask with a voice changer. There were plenty of masks lying around, but none with a voice changer. Your spare clothes were over there, but that's it. No incriminating evidence of any kind."

Conan thought a minute and said, "If she doesn't have the costume, it's possible she loaned it to someone. If she did that, then…"

"What is it, Conan-kun?" asked Kazuha curiously.

"It's just, someone could disguise as me, and if Haibara loaned them the costume, then she'd know who it was, and…" Conan suddenly blurted out, "Maybe this is all her doing! She loaned out the costume, and then 'dated' that person to make Ayumi-chan break up with me! Maybe we're all being played for suckers!"

"Who might it be, then, Conan-kun?" asked Ran.

"It would have to be someone who knew me well enough to impersonate me. It would also have to be someone around my body size, and it would have to be someone who wouldn't mind staying alone with Haibara. So, if I had to take a guess, I'd have to say Mitsuhiko."

Heiji said, "That's your friend the science nerd, right?"

"Yeah."

"Then I'll investigate him!" proclaimed Heiji. "Where does he live?"

Conan told him the address, warned him to be careful, and hung up.

Heiji immediately went out to scout Mitsuhiko's house. He noticed that the house was rather large, and he lived there with his parents and his older sister, who was a teenager. He noticed that one window was left open a crack, and he planned to use it to get inside later. He then went back to the Kudo Mansion.

That night, all four Tsuburayas went out to eat, and Heiji took his chance. He'd left a small video camera across the street with a live feed, and he'd been watching the house. He then went there, slipped inside, and started poking around. He found Mitsuhiko's bedroom pretty quickly, and started looking around. The closet turned up nothing, as did the dresser. Heiji was glad the room was somewhat messy, since he didn't have to worry about being such a neat freak like he'd had to be earlier.

Suddenly, he spotted Mitsuhiko's backpack leaning on a wall. He opened it, and quickly found what he'd been looking for: the disguise. He still didn't find the voice mask, but he took a quick picture of the evidence with his phone, replaced everything, and slipped back out.

After he was some distance away, he called Kazuha and told her to meet him at the Detective Agency. He then headed there himself.

Upon arriving, he then proceeded to tell everyone what he'd discovered, and used the photo he took as evidence. Conan was furious.

"How dare she treat me like this! After everything I've done!" He ranted for about five minutes, ignoring Ran's attempts to calm him down.

Ran suddenly said, "I'll talk to Ai-chan about all this. Hopefully I'll get her to stop."

Conan doubted it, but he reasoned it was better than him getting ahold of her, so he consented. Heiji and Kazuha returned to Osaka, their job done, and Conan went to sleep feeling much better, since he knew now that he wasn't crazy.

I should be able to finish publishing this story, as it only has around two more chapters or so. I could make it longer, but I feel as if I've dragged it on long enough, and it's time for Conan and Ayumi to get down to business. Next up, Conan takes care of Haibara, but how will he do it without breaking her heart?

Also, I submitted a comment to my own story to give people a chance to PM me if they choose to do so, if you don't like reviewing.
