Monster sitting

Jamie was babysitting two kids. It was a Friday night, and it was raining really hard. They were watching tv in the living room and suddenly they heard a loud THUMP.
« Wh-wh-what was that? » asked the little girl named Cleo.
« I'll go see »said Jaime. She walked over to the door leading to the basement.Just then, someone touched her back. She turned around and Cleo was standing there around and Cleo was standing there staining with a horrified expression on her face.
« S-s-someones d-down there » she said in a voice that wasn't her own. It was deeper and much more grown up.Jaime turned to look, which was a tragic mistake. The light had been turned on and a little boy much like the one she was babysitting was lying on the ground, pale.
« Bobby!! » she said horrified of the sight before her. « Say something!please! » she runs down the stairs, and hears a faint laugh from the top of the stairs. »Cleo, tell me that was you, sweety. »she says nervously. No response. Until she hears a voice.
« I'm NOT Cleo » she turns around, and right there only a foot or two away is a clown plunging a dagger into her heart. Everything goes black, and her life is no more.
