Rain lashed against the heavy glass of the study window. Lord Harrington sat slumped and silent in his leather armchair. A crimson stain bloomed slowly across his pristine white shirt. Arthur stepped into the dark room, holding a silver tray. The heavy metal teapot clattered loudly onto the oak floor. A single broken glass lay shattered near the velvet drapes. The grandfather clock struck midnight with a long, ominous chime. Someone inside this quiet mansion was a very clever murderer.
