The heavy rain poured down upon the creepy mansion tonight. A lifeless body lay silently inside the damp dark room. Crimson blood pooled around the victim's still and pale form. The detective arrived quickly to examine all the available clues. An open window suggested possible escape by the unknown killer. Thunder crashed loudly outside as he began his careful search.
