# The Briarwood Murders The morning fog clung to the narrow cobblestone streets like a pale burial shroud draped carefully over the sleeping village. Margaret Holloway discovered the body at precisely six fifteen on Tuesday morning, just before her usual walk through the churchyard. The dead man lay face down upon the wet grass, his arms stretched outward like a carefully arranged fallen angel. His expensive dark suit was torn at the shoulder, revealing a crimson stain that had soaked deep into the linen. A single white rose rested carefully in his right hand, though no roses grew anywhere within miles of this village. Constable Brennan arrived just twelve minutes later, his heavy boots crunching loudly against the gravel path beside the old church. He recognized the dead victim immediately and felt his stomach drop like a heavy stone falling into dark freezing water. It was Thomas Whitmore, the wealthiest man in Briarwood, who had been seen arguing loudly at the pub last night. Everyone in the village had reason to resent Thomas Whitmore, but who among them was truly capable of committing murder? The constable knelt beside the body and noticed something peculiar scratched into the mud beneath the dead man's outstretched fingers. Three numbers had been etched carefully into the wet earth: four, seven, one, arranged in that precise and unsettling order. Brennan pulled out his phone with trembling hands and dialed the only detective who could possibly understand what this meant.
