The rain lashed worn oak shutters of Hawthorne’s isolated manor. Housekeeper Maggie halted her climb beside the third-floor landing railing. Blood seeped slowly from under the locked study’s thick door. Her ragged gasp drowned nothing near the raging winter storm. A cracked grandfather clock chimed midnight through the manor’s walls. Her trembling fingers wrapped around her set of brass keys. The lock clicked open on a gruesome still unsettling scene. The billionaire owner lay sprawled across his ornate mahogany desk. A single antique dagger protruded from his bare torn throat. Wind whistled through a broken window at the room’s dark back. Every wealthy guest hid a secret they’d kill to protect.
