the lost sister---DUMBEST POSSIBLE VERSION

No one heard as she slithered up the drain pipe. Not a noise as she eased open the window. The only sound was the pitter patter of the rain on the black tin roof, the soft padding of the servant girls feet as the window was closed. When the girl passed she willed herself to become a shadow on the wall. She spent a day trailing lord Vaki, the little brute. She spent an hour learning how to get in. an hour to learn the guards shifts. An hour to find his room. Then she waited till the next rain. With her knee length black hair tied in a braid she opened the grand mahogany door, with barely a groan, and waited for the next peal of thunder to close it. As she slipped towards the bed where the lord and lady were sleeping, she drew her dagger from the scabbard at her shoulder with a whine. She was about to slit the lady's throat, she woke up and almost screamed. She shut up soon enough, but the noise woke lord Vaki. He begged for his life. She was not one to give mercy. Without the merest trace of regret she slit his throat too.......
