Horror in Hampstead -1

Guy Winstead liked little girls. And not in a nice way. He befriended them in internet chatrooms and lured them out to meet him so that he could abuse them. Yet he was also cunning. No-one knew that he, a respectable city businessman, was a secret child-abuser. He thought he was safe, that he was too clever for the police. A dozen little girls were afraid of him, and of other men. They'd lost their innocence early, and some were too terrified to leave the house. But Guy Winstead didn't care. He was happy, and that was all that mattered to the callous and evil man.
He had been speaking to the little girl called Stephanie for two months on the internet, and he had won her trust. He'd sent her a picture of him as a boy, and she'd sent a picture back. He looked at it. It showed a pretty girl with flame-red hair, a girl of about ten, barefoot, in a garden in India. She had just come back from there, her parents were missionaries. He'd pretended his father was a vicar, and she'd opened her heart to him.
Now he was waiting for her on ampstead Heath as the night fell, waiting to take her and abuse her.
Guy let the night fall as he fantasised about what he would do to this trusting little daughter of missionaries. He closed his eyes and laughed to himself as he dreamed up the most revolting thoughts. All of them involved the redheaded girl in the snapshot he held - and all of them would have got him sent to prison if he'd acted them out.

"Is Timmy Henderson around here?"
The abuser opened his eyes at the sound of the little girl's voice speaking the false name he'd given on the chatroom. It came from behind him.
"Yes," he turned.
The smile dropped from his face at once. What he faced was not the pretty redhead he had expected to see, but a weird black smoky figure the size and shape of a little girl. Its only discernable features were two red eyes that blazed like live coals in a black smoky face.
"Hello Guy Winstead," The Outsider said. " I am the Outsider, and this evening you're going to die"
