The Witch's Pastime: Final Act Following up on phrases left by the witch serial killer, Ashaf, Guideau, and Haines investigate a bookshop, but they find the owner gruesomely murdered. Haines refers to the current murder spree as a "Witch's Pastime" because she believes it's just a game to them. After the witch attacks Ashaf and Guideau, they deduce the witch is somehow linked to Haines. They confront Haines, who admits that the witch killed her children and then her lover, targeting those close to her. The witch stages an attack on the police headquarters, but Ashaf uses his crows to follow the witch to her hideout. They discover that Haines's two adopted sons, Shulk and Loran, are the perpetrator after coming into possession of set of grimoires, Sarnouasuth. Although they claim the grimoire forced them to kill, Haines states they went too far and shoots them both dead. Ashaf takes the grimoire for safekeeping.
