Jina picked up Junho from Bomi's house and went to the national library where there was a section dedicated to Demonology, a study on demons. It was not completely accurate most of the time but there were instances when they stumbled across useful information. Hobin already texted her about what he found out from Myungsoo and they were now worried.
"Song Aina is killing these people simply to test her website?" Junho frowned.
"She's probably trying to hide her involvement in her husband's murder," Jina muttered. "There's no proof against her unless the site is tracked back to her. If we arrest her now, she'll claim in court that she has no connection to the other victims and hence, she's not the murderer in all the cases."
Junho nodded and picked out a pile of books. The library was open all the time so they were able to enter it. Moreover, he was friends with the librarian and let him use the restricted section where the books on demons were available.
