Cold autumn rain battered the tall stained glass windows of the silent manor while Detective Miller examined the pale corpse. Lord Blackwood lay sprawled across the expensive Persian rug with a silver letter opener buried deep inside his broad chest. The heavy oak doors remained bolted firmly from the inside, leaving absolutely no obvious escape route for the clever assassin. A shattered crystal brandy glass rested near his limp fingers beside a single crimson rose and a cryptic handwritten note. Miller slipped on thin white cotton gloves and carefully lifted the folded parchment toward the flickering light of the fireplace. Downstairs in the grand parlor, five wealthy guests waited nervously because every single person there held a dark, deadly motive. The veteran investigator smiled grimly as thunder shook the old house and the hunt for a ruthless murderer officially began.
