Cold rain tapped relentlessly against the dark, cracked window pane. Lord Harrington lay completely still upon the crimson velvet rug. A silver letter opener protruded sharply from his torn chest. Thick dark blood pooled slowly around his expensive gold watch. Inspector Vance stepped quietly into the dark and dusty study. He adjusted his wet coat and smelled a bitter aroma. A broken glass lay shattered near the dead man's hand. The grandfather clock chimed midnight, echoing through the empty house. Vance knew immediately that the vicious killer remained very close.
