Gray twilight seeps through the old library’s cracked front windows. A soft creak echoes as the front door swings open. Dr. Hale, the lead detective, steps quietly across the floor. The slim silver knife juts from the elderly victim’s chest. A single torn receipt clutches tightly in the dead fist. A leather-bound journal lies open face-down on the wooden table. A shadow lingers just beyond the dusty library back doorway. The air smells thickly of iron and burnt old parchment. Dr. Hale’s jaw tightens as she takes in the quiet scene.
