Model response

The frosted panes of the derelict library let me glimpse a slumped body whose pale hand gripped a broken locket. I fumbled with my coat buttons before bursting inside to kneel beside the victim and check for a faint pulse. A 1920s letter tucked in his vest pocket fluttered open to reveal a scrawled threat signed with a crimson stamp.
