Rain hammered the dark alley as Detective Mara arrived beside the cold body hidden beneath a torn red curtain nearby. Her flashlight revealed a silver locket clutched in the victim’s pale hand, engraved with strange initials nobody present could recognize. A distant siren moaned while Mara noticed fresh mud leading toward the locked door of the abandoned theater standing alone.
