Rain beat violently against the tall glass windows tonight, unyielding. Detective Thomas stepped slowly into the dimly lit study room. Lord Harrington lay completely still upon the ornate Persian rug. A heavy silver dagger stuck out from his bloody chest. The ancient grandfather clock chimed midnight with a somber tone. Nobody inside the mansion had heard any suspicious noises earlier. Thomas knelt beside the cold corpse, adjusting his black gloves. A torn piece of parchment was clenched within his hand. The killer left no obvious footprints on the polished floor. The deadliest game in town had officially just begun tonight.
