A/N: This is my first Detective Conan story or what I would say: Detective Heiji Hattori story. I'm sorry but my English isn't the best.
Disclaimer: As you probably know, I do not own Detective Conan.

YOU SHOULDN'T FORGET

Chapter 1 (17 years is a long time)

On a cold day in December, The young Detective of the west walked down the streets of Osaka on his way home from school. He was supposed to walk with Kazuha, but she was so late that he wanted to go before he was frozen to the ground. There were a long way home, but lucky for Heiji, He could some shortcuts. And the next thing he knew he was at least 100m away from his home. The only thing he needed now was too walk to the right in the next junction.
On both sides of the road there were two gray walls that swung in opposite directions at the junction. Heiji walked down the road thinking about what Kazuha had said When he wasn't waiting for her and what his mum would said after he comes at least 20min late for dinner, Because he had to wait for Kazuha.
He was about to swing to the left When he surprised saw his dad (Is just out of his office when it is something important.), Okita-Han (Okita Goro, a police/Detective in the Osaka police district. It's Heiji that calls him Okita-Han) and Chief Toyama (Kazuha's dad, I don't know what to call him.) Their faces looked quite serious. They had obviously not seen Heiji that was just 10m from them. Heiji hadn't seen them either because they were too long to the left. Heiji had really wanted to see what's happen, there where at least 4 police cars there and it seemed like that they had just got here. But that would just be stupid; Because Heiji and his dad had a fight last night about "heiji's Detective work." So Heiji decided to listen. Heiji snuck up carefully to the left wall, so that he could hear well and not be seen by them.
"It looks like a murder. The victim was shot with a hand gun." Okita-Han said seriously
"But Detective Okita-San, you wouldn't had called me hear if it wasn't something really important." Mr. Hattori said important. (I'm calling Heiji's dad Mr. Hattori from now on.)
"Yes, it was that. It was laying a letter beside the victim, with your name on it, We Think it's from the killer." Okita-Han said serious and gave Mr. Hattori the letter. Mr. Hattori started to read out loud to the two officers what that stood on the letter. Their faces got more serious after awhile: Dear Heizo Hattori. It's a long time ago. 17 years ago since you got your son. 17 years ago you took away my left hand. 17 years ago since I said I wanted revenge. 17 years has it gone and you have never found me. 17 years is a long time.
- Serial killer
"Is that who I think it is?" Chief Toyama asked serious.
"I..."
Chief Toyama was stopped in his sentence by his Dear daughter's voice.
"Heiji! I said to you that you had to wait for me, not walk before I come out."
