The rain fell hard against the mansion’s stained-glass windows tonight. A guttural scream echoed through the halls of Blackwood Manor, cutting silence. Blood pooled beneath the grand piano, its keys still trembling faintly. The guests, gathered for dinner, froze in terror at the sound. Detective Harlan Graves adjusted his hat, sensing death lurked nearby.
