Soul of a Heretic

A Monster's Soul is the 59th chapter of the Attack on Titan manga, written and illustrated by Hajime Isayama.

Overview
Nile Dok ponders over whether the Military Police Central Branch will use the new Maneuver Gear against regular Military Police while the press attempt to get answers. Armin comes to terms with committing his first crime, although Levi and Jean encourage and thank him, respectively. Two soldiers, Hitch and Marlo, are caught when they stray from their patrol group and are detained by Squad Levi. Hitch discovers the truth about Annie Leonhart, while Marlo pleads to help Levi. Jean is given custody of the captured pair; he tests Marlo's honesty by having a brief fight, and Hitch tries to intervene. They both agree to aid the Survey Corps. Using Marlo's intel, the group locates what is very likely the Central MP HQ where Eren and Historia are being kept.
