Suddenly leah and julie were surprised because they suddenly remembered leah's parents words. they ran to julie's room and leah said:

"julie, remember what my dad said about the murderer?" while saying that tears fell down from leah's eyes.

"yes, I do remember"

And they both said together "Benjamin , he is the one who know laws... am sure he is the killer"

"this is what your dad said, so the twin of dr johnson or simply Dr. john, He is benjamin?" julie was so surprised. so do leah.

"yes, I think so "
