Heiji is ready to run around Third District of Beika City because he was sure that he can find the house of the sender. After breakfast,he prepared everything he brought. He was about to live when Ginzou Nakamori said something to him.

"After that,will you please go to Beika Museum?",the inspector requested.

"Why?",Heiji asked.

"Because Kaitou Kid set up a heist again.",Ginzou warned.

"I'll go there as soon as I'm finished. Bye,Inspector!",Heiji said as he leaves for Third District.

"Dad,are you sure that Hattori-kun would make it in time? You know that it's nighttime each time he deciphered a code.",Aoko asked her father.

"I'm sure! He just have to solve it earlier now. After all,he's the Great Detective of the West.",Ginzou said.

Heiji is running around Third District,but couldn't find the sender's house.

"My neighbor has a big brain but usually goes blank. What did I get myself into? I'm almost there and yet I couldn't find that house.",Heiji thought.

While running around,he spotted two houses. There was a girl outside the house in the right side. He was sure she can give the answer to his question. However the girl,who has a auburn hair,stepped forward to get close to Heiji. She sees him as a familiar person to her. Heiji either sees her as a familiar person.

"Osaka friend,I know what you're thinking,but the answer does not belong to me because Professor Agasa is the key to the answer.",she said.

However,Heiji is staring at her then he finally spoke.

"You're Ai Haibara! You're back to your original body!",he confirmed.

"My name is Shiho Miyano,not Ai Haibara.",she confirmed.

"By the way,is Professor there?",he asked. He remembered Hiroshi Agasa.

"Yes,but he's doing something.",Shiho answered.

"And if you're finding the sender and the writer of the code......",she almost added but she saw Heiji staring at the house of Agasa's neighbor.

Something came into his mind.

"There! That's where the sender lives! In that mansion-like house!",Heiji confirmed.

He was about to go to the house but Shiho warned him.

"Facing the circumstances yourself will not do. And also,she had lied to you about her knowledge about this.",she said.

"Who lied to me? The neechan or Suzuki?",Heiji asked.

"You'll know as soon as you enter the house. She is there with her friend",Shiho said.

"Well,I'll face those circumstances myself! I'll know who sent this code to me.",he insisted.

"Be careful,Osaka friend.",she said.

Now Heiji found the house of the sender,will he manage to discover what's behind the mystery? Will he discover what's behind Sonoko's lies? The answer he was finding for a long time will come out......

As the secret that is long hidden will be revealed....

"He's ready to face us.",a voice said.

"Yeah. And he'll be shocked for this surprise we have.",Sonoko's voice said.

"Are you ready?",the girl that is Sonoko's friend was talking to someone.

"Well........It's.....a.......pleasure.........to......see......him.........again.....",a voice answered.

"Hattori.......",it whispered.
